According to the different cross-sectional shape, steel is generally divided into sections, plates, pipes and metal products in four categories, the product is widely used in the production of various types of steel, In order to facilitate the organization of steel production, ordering supply and improve management, is divided into heavy rail, light rail, large section steel, medium steel, small section steel, steel cold-formed steel, high-quality steel, wire rod, steel plate, Electrical steel sheet with silicon, strip, seamless steel pipe, welded steel pipe, metal products, and other varieties. First, the production method of steel Most of the steel processing through the steel is pressure processing, so that the processing of steel (blanks, ingots, etc.) produce plastic deformation. According to the steel processing temperature is not the same as steel to sub-cold and hot processing two. The main processing methods of steel are: rolling: the steel metal blank through a pair of rotating roll gap (various shapes), due to the roll to reduce the cross-section of the material, the length of the pressure processing method, which is seamless The most commonly used mode of production, mainly used to produce steel profiles, sheet metal, pipe. Sub-cold-rolled, hot-rolled.
Forged steel: the use of reciprocating impact force forging hammer or the pressure of the press to change the blank into the shape and size we need a pressure processing method. Generally divided into free forging and die forging, commonly used for the production of large sections, such as cross-section open billet large steel material.
Drawing steel: is the rolling of the metal blank (type, pipe, products, etc.) through the die hole into the cross-section to reduce the length of the increase in processing methods are mostly used for cold work.
Extrusion: the steel will be placed in the closed steel extrusion Jane, one end of the pressure, so that the metal from the die out of the hole to be the same shape and size of the finished product processing methods for the production of non-ferrous metal products, steel .
