Shaped Steel

Shaped steel steel forming the associated to the steel products which are obtained after the reduction of scrap metal or cast iron through a process of lamination, classified into two large groups that correspond to the hot rolled and cold rolled. Hot rolled are all those elements that are obtained through what is called continuous casting processes and that they basically consist of a device that distributes in different lines of manufacture cast steel, this lines has arrays with the shapes that you want to produce that they can be channels profiles L, t straps, I standardized profiles section, etc, a very important element of this type of manufacturing is the wire rods which is nothing more than a metal that he is obtained by a process of hot rolling through a train specially designed to this effect, known as rolling the wire rod mill has section circulates or product oval that varies between 5 and 30 mm in outer diameterwhich is usually wrapped in coils of hundreds of metres, it can be said that this product uses are varied, another important product is the shield or recorder which are lengths of 6 m in steel or other material metal plates his utility is very wide, they are usually manufactured in the final form from the steel mill as a product. Continuous casting molds are water cooled and allow the formation of long lengths of the elements set out above, the application of them is fundamentally structural since due to the manufacturing process are considered practically isotropic and isothermal, and with a configuration of the constant material throughout its structure, for this reason the design techniques can be applied if inconvenient (correction factors) to the structural design. In addition to the previously described forming is necessary to control the cooling conditions to make these elements ductile since rapid cooling may result in the uneven hardening which translates to fragility of the product. The composition of this product may vary depending on the application and the process used but is usually running to find it with contents of coal of about 0.8%, proportions of other elements such as phosphorus from the 0.48%, manganese of 0.30% among other laminates in cold are those elements that come out of the metal plate and that after a process of machining acquired its final form, processes of machining are usually by zizalla cut and folded, these elements, due to the machining present efforts along the same concentrations, since they change their crystalline structure tending to be more hard in these areas but at the same time more fragile, so it is recommended the adoption of techniques of calculus punctual, with safety factors associated with this uncertainty in the distribution of loadscan be found in the form of channels C, G, angles, etc. have their most important application the what is called metal or ornamental woodwork without any inconvenience and are usually more economical than those because their manufacture is local while the first in their overwhelming majority are imported and their weight increases the freight.

First Nylon Bike

Blessed nylon. Since this artificial polymer was patented by DuPont in 1938, he hasn’t done more than solve us (requiring no ironing!) life. Now Bristol engineers have developed a new way to create as strong as steel nylon, a method of manufacturing that could revolutionize British manufacturing, as did the other Nylon with the American more than 70 years ago. The first object that have submitted is a bike so light and so resistant that amazes by his way of making both your line: using 3D printing. Chris Turner and Andy Hawkins, development in the Aerospace Innovation Centre in Bristol (UK) engineers, are responsible. The process that has been used to create the bicycle is what this aerospace cluster has been using to make parts of satellites and Airbus aircraft; It is capable of producing very complicated by printing structures and merge the cross sections of a tenth of a millimeter of depth to build parts in three dimensions.

Is It is called additive manufacturing (ALM) layered process and is basically very simple. Take a 3D object, which can be the seat of the bicycle, and cut into thousands of slices 2D. Print wedges in nylon and are then stacked to make an entire object. Everything starts from a powder heated nylon to 177 degrees C, about to melt. A laser traces the outline of the shape in 2D, melting into layers that powder. Then add another layer of 0.1 mm thick nylon powder and laser blows again it. Little by little, the object takes shape. Since everything is surrounded by dust, you can create solid objects in space, in other words, moving parts.

In fact bike has bearings, crankshaft, and wheels that spin, without additional parts.Engineers have reduced the bike about a dozen parties, which then joined together to create a machine finish trendy, but call to crush the road with its resistance. Although the bike is being promoted as as strong as steel, it is true that you one does not You can though doubt whether embarking on Tomb opened with the first prototype. It is the same thing that would think the first one that was hung from a building with a nylon rope to test its resistance. But the important thing here is the new manufacturing process. The real breakthrough is that the ALM print breaks the barrier between the designer and the manufacturing workshop. Design of parts using lathes, foundry, machining in Exchange is no longer necessary, the designer only is based on a 3D computer program and ALM machine prints you the product. And beyond of a bike it will be possible to make parts of the wing of a plane with hollow frame incorporated, saving weight and material. Even an F1 engine.Why then start with a simple bike? The proyecto-bici arose after the North West Aerospace Alliance, one of the world most recognized engineering associations, feel frustrated of not being able to adequately explain the process to anyone more than to other engineers or specialists. One of the creators stated in an interview for the BBC which I wanted to show my mother what I do at work and really didn’t understand it. But everyone knows what is a bicycle. It certainly seems to have been explained very well.

Perforated Sheets

Perforated sheet metal are used in many sites and areas. Bandwidth ranges from the production of metals, to use in machines and vehicles, electrical industry, energy production, food industry, civil engineering, architecture and interior design. In addition to these practical applications, they are also transparent and decorative and comply with a large number of tasks. perforated stainless steel sheet perforated sheet metal sorted, filtered, sieved and dosed. Thanks to its aesthetic aspect are used increasingly for architectural purposes. Create special for interior decoration design options in relation to the incidence of direct or indirect light.

They also serve as panels of security, grills, sieves, vibrating sieves, filters, cladding for facades and balconies, as well as protections against noise, partition walls, balustrades and railings. With perforated sheet metal beads of different sizes are separated and they can also be separated the solids from the liquid. They also filtered and separated liquid substances of different consistency. In the hydraulic construction serve as tubes and are also used in seawater desalination plants. They are subsequently divided, regulate and dosed the water and other liquids. The perforations exist in various shapes and sizes.

There are holes square, round, rectangular, hexagonal, star-shaped, oblong, diamond and you can also create designs tailor-made according to customer’s request. Perforated sheet metal are made of various types of veneer as e.g. Stainless Steel AISI 304-316, galvanized steel, carbon, aluminum, brass, titanium steel, corten steel, polypropylene etc. Commercial plates sizes are 1000 2000 mm, 1250 2500 mm and 1500 3000 mm, but sheets according to customer’s specifications can also be fabricated. Perforated metals are carried out by specialized companies with decades of experience in large series or made to measured according to each customer’s requirements. The drilling machines work with a pressure of up to 500 tons. Electronic controls ensure maximum precision. General information: Actis Furio srl is a company specialized in sheet metal drilling and operates in the national and international market. The company was established in 1950 in the North of Milan. In 1988 moved a new plant in Cornaredo, in the province of Milan and added new offices come the departments of sales and export, research and development, technical and quality control. Acits Furio enjoys numerous certificates of quality eats e.g. UNI EN ISO 9001: 2000 and ISO 9001: 2008. Thanks to its program of continuous investment in new technologies, including CNC machinery, Actis Furio has consolidated itself as a European leader in the manufacture of perforated sheets.

Stainless Steel

Over the years, stainless steel has high demand in their use, especially in our daily life. As it is synonymous with functionality, warranty, elegance, hygiene and durability, stainless steel has become reference material for a without number of options, since unlike other metals, it contains chromium, which makes it resistant to corrosion and nickel, which gives the color silver, making it ideal for the manufacture of any element to be used both in indoor and outdoor: street furniture, kitchens, restaurants, hotels, utensils surgical, docks, boats, bathrooms and playgrounds, among others. It is a material with which you can work easily; It is ideal for the manufacture of elements of fasteners such as screws and anchors, decorative pieces, separators for panels and glass, fasteners for cables, turnbuckles and shackles, elbows, or ples and clamps among others. Uses addition, used in construction such as structures, coatings, facades, lighting, covering of floors, ceilings and decorative finishes, giving prominence to the space where it is used, for its high range of surface finishes: Matte, glossy, polished, frosted and satin. Stainless steels offer a high resistance to corrosion, an appropriate relationship with the resistance, mecanica-peso; also hygiene, resistance to elevated and cryogenic temperatures and properties long term value. This metal is divided into several types according to the place or use that apply you. The most traded types are 304 and 316. The difference existing between these stainless steels lies in that 304 contains chrome to 18 per cent and nickel to 8%, while 316 contains chrome to 16%, 10% and 2% molybdenum nickel, being this last element that provides corrosion resistance against chlorides (such as sea water and salts which defrost)who see the stainless steel for coastal applications and salt corrosion..

Nondestructive Testing

Non-destructive testing in the steel industry of material with ultrasonic non-destructive tests have more than 40 years old. From the earliest times, with oscillations of ultrasound for detection of defects in different materials, it has become a classic test on the basis of measurements method taking into account all the factors that influence. Today expected that tests of ultrasound, supported by great advances in the technology of instruments, can give reproducible results test inside margins reduciso. This assumes exact knowledge of the factors that influence and the ability to apply these in the tests. Not all influences have to be seriously considered by the operator. In many cases, some of the influences can despise without exceeding the limits of tolerance that the measurement allows, which simplifies the test sequence and reduces test time. In the early 1950s, the technician only knew radiography (x-rays or radioactive isotopes) as a method for the detection of internal defects, as well as the methods of non-destructive testing of the surfaces of materials, e.g., Dye penetrant and magnetic particles. Even more, Yy was developed after World War II, the method of ultrasound, as described by Sokolovin 1935 and applied by Firestonein 1940, various instruments were soon available for ultrasonic testing of materials.

The principle of ultrasound is based on the fact that solid materials are good conductors of sound waves. By the fact that the waves are not only reflected, on surfaces, but also by internal flaws (separation of material, inclusions, etc.) the effect of the interaction of the waves of sound with the material is stronger the smaller wavelength. This means that waves of ultrasound should be used in a range of frequencies between 0.5 MHz and 25 MHz and that the resulting wavelength is in mm. With lower frequencies, the effect of the interaction of the waves with internal failures would be so small that detection becomes questionable. Both methods of testing, x-rays and ultrasound tests, methods are most commonly used tests of different parts of internal fail-safe.

This means that today’s tests are possible with the method most economical test and not risk ultrasonic; on the other hand special test problems are solved, as before, with the x-ray. In cases that require the highest security requirements (e.g., nuclear power, aerospace plants), you can use both methods. Ultrasonic (UT) can identify changes in bearings, gears, and the rotating machinery due to changes in load or wear. Other methods of ultrasonic inspection as the pulse-echo technique can detect faults and estimate the size comparison of the amplitude of an echo reflected from an interface with an interface of known size reference. The gauges are often calibrated with samples of a known thickness, density or mass.

People in this quadrant will respond to fear not by the quest for security, but to take control of the situation and deal with it by themselves. That’s why I call them the Group of do it yourself. In what refers to the fear and financial risk, they want to take the bull by the horns. In this group you will find well-educated professionals, who spent years in school, such as doctors, lawyers and dentists. Used auto are commonly rooted perfectionists. They often want to do something exceptionally well.

In his mind they feel that nobody makes it better for what they can do, so really do not trust that no one else can do as they like in the manner which they consider is correct. This group often has difficulties to hire other people to do what they do, simply because in his mind nobody is capable of performing the task.

This causes that the members of this group say often: is difficult to find good assistants in these days. Many people type A are reluctant to hire and train other people since trained once they often end up as its competitors. This factor, in turn, keeps them working harder and doing things on their own. 3 D (business owner). This group of people could be almost the opposite of the A.

Those who are real D like to surround himself with smart people from the four categories, E, A, D and I. A D true motto is why do it yourself when you can hire someone that do it for you and they can do it better? Those who are real D can abandon their business for a year or more now her return find that your business is more profitable and better directed than when they left. In a true type of business, if the run for a year or more, there are many chances that there will be a business which return. Then, what is the difference? To put it simply, an is owner of a job. A D owns a system and then hire competent persons to operate the system. Take for example the case of a dentist. A dentist spends several years in school, learning to become a self-contained system. You, as a customer, have toothache. You come to see the dentist. He arranges his tooth.You pay and goes home. You’re happy because continuation tells their friends about your great dentist. In the majority of cases, the dentist can do all the work by himself. The problem is that if the dentist goes on vacation, also your income does. Business owners D can go on holiday for ever since they have a system, not a job. If the D is on vacation, the money still entering. 4. The 1st (Investor). Investors make money with money. They do not have to work because your money is working for them. Quadrant I is the playground of the rich. No matter in what quadrant people have earned their money, if they wish to someday be rich go ultimately to this quadrant. It is in the I quadrant in which the money is converted into wealth. Eng.
