Rolled metal is a certain metal product, the production process of which is based on the use of rolling machines using hot, cold and warm rolling. The managers of the company lsr-steel.ru tell about the production and use of rolled metal products.
Production of rolled metal
Rolled metal is produced by clamping the metal between two, and in some cases three rollers on a rolling machine, they rotate in opposite directions relative to each other. Thus, the metal blank is fixed between the machine rollers and pulled out. Depending on the temperature indicators used at the time of rolling, there is hot rolling (the temperature is higher than the metal recrystallization limit), as well as cold rolling, when the temperature does not exceed the recrystallization barrier.
Varieties of modern rolled metal
Rolled metal products are divided into the following categories:
- Sheet products. This category of rolled metal should include rolled and sheet steel, strips, and tin products;
- Long products. Hexagons, building fittings, strips and circles;
- Shaped steel Channel bars, rails, I-beams, steel angles;
- Tubular rolled products. Seamless and welded steel pipes.
Scope of use of rolled metal
Today the sphere of direct use of rolled metal products is very wide. It is actively used in the construction of both railway and road bridges, in the construction of houses of a domestic, public and industrial nature. The most familiar metal rolling for an ordinary person is “stainless steel”. It is often used in everyday life, since it is on the basis of this material that the production of household knives, cutlery, plumbing, dishes and much more is based. Such rolled metal is used almost everywhere where resistance to the negative effects of corrosion is required. In agriculture, this material is used for the construction of machinery and equipment, for the manufacture of inventory. Not a single modern building of an agricultural nature can be erected without the use of high-quality rolled metal. Cold-rolled metal is used for the construction of aircraft, cars, trains, for the construction of towers for mobile and cellular communications. In the food industry, it is used as pipes for transporting food products under the influence of high temperature indicators.
As you can see, the field of application of this building material is very extensive, in fact, this is due to its great demand for modern
