Steel is the essential material for the construction and realization of the four countries. It is widely used and has a wide variety. According to the different shape of the cross-section, the steel is generally divided into four parts: profiles, plates, pipes and metal products. Class, in order to facilitate the organization of steel production, order supply and do a good job in management, and is divided into heavy rail, light rail, large steel, medium-sized steel, small steel, steel cold-formed steel, high-quality steel, wire, Steel, electrical silicon steel, strip, seamless steel pipe steel, welded steel pipe, metal products and other varieties. First, the production of steel Most of the steel processing are steel through the pressure processing, so that the processing of steel (billets, ingots, etc.) plastic deformation. According to the steel processing temperature is not the same as the cold and cold processing of two kinds of hot processing. The main processing methods of steel are: rolling: the steel metal blank through a pair of rotating roll gap (various shapes), due to the compression of the roll material to reduce the cross-section, the length of the increase in pressure processing methods, which is the production seamless The most commonly used production method of steel pipe is mainly used to produce steel profiles, plates and pipes. Min cold rolling, hot rolling.
Forged steel: the use of forging hammer reciprocating impact or press the pressure to change the blank to our desired shape and size of a pressure processing methods. Generally divided into free forging and die forging, often used for the production of large profiles, billet and other cross-section steel material larger material.
Pulling steel: is the rolling of the metal blank (type, tube, products, etc.) through the die hole to reduce the cross-section to increase the length of the processing methods are mostly used for cold processing.
Squeeze: the steel will be placed in a tightly pressed metal extrusion, one end of the pressure, the metal from the specified die hole out to get the same shape and size of the finished product processing methods, and more for the production of non-ferrous metals steel The
