Rolled metal is very popular in industry and construction. Large factories are engaged in the manufacture of products, strictly observing the technology regulated by GOSTs. For this, different production methods are used, depending on the type of product that needs to be obtained. The enterprises are equipped with modern automated equipment, which makes it possible to produce and sell rolled metal in Moscow of all categories in any volume.
Methods of manufacturing products
Quality is rolled products manufactured in compliance with the technology. Therefore, you need to buy products from suppliers that cooperate with trusted manufacturers. You can profitably order metal products on the website of a specialized online store https://metallink.ru/, which has established itself as a reliable partner. The company has quality certificates from manufacturers.
Enterprises produce rolled metal products using modern technologies:
-
Hot rolling method. In rolling mills, steel billets are subjected to plastic deformation, passing between the rollers. As a result, the original shape of the products changes. Before that, the metal is heated to a temperature of + 900 ... + 1100 degrees. The hot-rolled method is used to produce sheet metal, strip, circle, square, rebar, wire rod, channel.
-
Method of cold deformation. Steel billets are also heated and then pressurized. But the heating temperature is 2.5-6 times lower than that of hot rolling. During cold deformation, the metal retains its high corrosion resistance, strength, and accuracy of geometric parameters. This method is used to produce rolled pipes, sheet steel, fittings for various purposes.
-
Bending method. The technology is mainly used for the production of angle bars, channel bars. Products are made from cold-rolled or hot-rolled steel billets on roll forming equipment. This method makes it possible to produce rolled products with thin walls, which reduces the metal consumption and, accordingly, the cost of the finished product.
In the production of rolled pipes, the technology of drawing, welding or a seamless method of manufacturing products is used. The specificity of the technological process depends on what material is used and what characteristics a particular type of rolled metal should have in accordance with the established standards. In Moscow, you can order cheap metal products of all categories.
Additional processing
For the manufacture of products, low-carbon, high-carbon, alloy steel of ordinary and high quality is used. In the factory, the products are subjected to additional processing to improve the technical characteristics of rolled products:
-
sheet rolling on press stands;
-
galvanized for corrosion protection;
-
annealing (hardening) to increase strength;
-
training to lower the yield stress;
-
final compression to improve the surface micro-relief.
High-quality rolled products should not have chips, shells, cracks, scale, burrs on the edges. Products must comply with geometric parameters and technical requirements. You can buy good rental at a bargain price with delivery to the construction site from a trusted supplier.
