Production method of steel

Most steel processing is through pressure processing, which plastically deforms the processed steel (bill, ingot, etc.). According to the different processing temperature of steel, it can be divided into cold working and hot working. The main processing methods of steel are:

Rolling: The metal billet is passed through the gap (various shapes) of a pair of rotating rolls, and the material section is reduced and the length is increased due to the compression of the rolls. This is the most commonly used production method for steel production. It is mainly used for production of profiles, steel plates and steel pipes. Rolling is divided into cold-rolled and hot-rolled.

Forging: A press working 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 large cross-sectional dimensions.

Drawing: It is a processing method in which the rolled metal billets (forms, pipes, products, etc.) are drawn through the die holes to reduce the cross-section and increase the length. Most of them are used for cold working.

Extrusion: It is a processing method in which the metal is placed in a closed extrusion tube, and pressure is applied 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 for the production of non-ferrous metal materials.
