Most steel processing is done through pressure processing, causing plastic deformation of the processed steel (billets, ingots, etc.). According to different steel processing temperatures, there are two types of cold processing and hot working. The main processing methods for steel include:

1. Rolling: A pressure processing method in which metal billets pass through the gaps (various shapes) of a pair of rotating rollers, causing a reduction in material cross-section and an increase in length due to compression by the rollers. This is the most commonly used production method for producing steel, mainly used for producing profiles, plates, and pipes. Divided into cold rolling and hot rolling.

2. 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. It is generally divided into free forging and die forging, and is commonly used for producing large materials, billets, and other materials with larger cross-sectional dimensions.

3. Pulling: refers to the process of drawing rolled metal billets (shapes, tubes, products, etc.) through die holes to reduce the cross-section and increase the length. Most of the processing methods are used for cold processing.

4. Extrusion: It is a processing method that places metal in a closed extrusion chamber and applies pressure at one end to extrude the metal from a specified mold hole to obtain finished products of the same shape and size. It is commonly used in the production of non-ferrous metal materials.
