Most of the steel processing is the pressure processing of the steel, which causes the processed steel (billet, ingot, etc.) to produce plastic deformation. According to the steel processing temperature, the steel can be divided into cold processing and hot processing. The main processing methods of steel are:
1. Rolling: A pressure processing method in which steel metal billets are passed through a pair of rotating rolls (various shapes), the cross section of the material is reduced due to the compression of the rolls, and the length is increased. This is the most commonly used production method for producing steel. Mainly used to produce steel profiles, plates, and pipes. It is divided into cold rolling and hot rolling.
2. Forging steel: a pressure processing method that uses the reciprocating impact force of a forging hammer or the pressure of a press to change the blank into the required shape and size. Generally divided into free forging and die forging, it is often used for the production of large-scale steel, billet and other materials with larger cross-sectional dimensions.
3. Drawing steel: the processing method of drawing rolled metal blanks (forms, tubes, products, etc.) through die holes to reduce the cross section and increase the length is mostly used for cold working.
4. Extrusion: It is a processing method in which the steel puts the metal in a closed extruder and applies pressure at one end to extrude the metal from the specified die hole to obtain a finished product with the same shape and size. It is mostly used to produce non-ferrous metals. Material steel.
