A little knowledge of steel

Steel is an indispensable and important material for national construction and Realization of the Fourth Century. It is widely used and has a wide variety of varieties. According to the different section shapes, steel is generally classified into types.

In order to organize the production, ordering and supply of steel products and do well in management and management, the four major categories of steel, plate, pipe and metal products are divided into heavy rail, heavy rail and heavy rail.

Large section steel, medium section steel, small section steel, cold-formed steel, high-quality section steel, wire rod, medium-thick steel plate, thin steel plate, silicon steel sheet for electrical purposes,,

Seamless steel pipe, welded steel pipe, metal products and other varieties.

2. Production Method of Steel

Most steel products are processed by pressure, which results in plastic deformation of the processed steel (billet, ingot, etc.). According to the processing temperature of steel, there are two kinds of different processing methods: cold processing and hot processing. The main processing methods of steel are as follows:

Rolling: The rolling of steel and metal billets through a pair of rotating rolls gap (various shapes), due to the reduction of the cross section of the material by the compression of the rolls, the length of the increased pressure processing method, which is the most commonly used production method of steel products, mainly used to produce steel profiles, sheets, pipes. It is divided into cold rolling and hot rolling.
