Steel production method

Most of the steel processing is through pressure processing, so that the processed steel produces plastic deformation. According to the different processing temperature of steel, it can be divided into two types: cold processing and hot processing. The main processing methods of steel are:

Rolling: A pressure processing method in which a metal blank is 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. Production of profiles, plates, pipes. It is divided into cold rolling and hot rolling.

Forging: 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 shape and size we need. Generally divided into free forging and die forging, it is often used to produce large materials, billets and other materials with larger cross-sectional dimensions.

Pulling: The processing method of drawing rolled metal blanks (forms, tubes, products, etc.) through a die hole to reduce the cross section and increase the length is mostly used for cold working.

Extrusion: It is a processing method in which the metal is placed in a closed extruder and pressure is applied at one end to extrude the metal from a prescribed die hole to obtain a finished product with the same shape and size. It is mostly used to produce non-ferrous metal materials.
