Steel pressure processing methods
In the production of the steel industry, the vast majority of steel products are made by plastic processing or by plastic processing first and then other processing. The so-called metal plastic processing is a processing method that uses different equipment and tools to apply external force to the metal to cause plastic deformation and produce products with expected size, shape and performance. It is also called metal pressure processing.
Explanation of steel pressure processing methods
Most steel processing is through pressure processing, which causes plastic deformation of the processed steel (billets, ingots, etc.). The main processing methods of steel are:
1. Pull
Drawing is a processing method that draws the rolled metal blank (shaped, tube, product, etc.) through the die hole to reduce the cross-section and increase the length. Most of them are used for cold working.
2. Squeeze
A processing method in which metal is placed in a closed extrusion cylinder and pressure is applied on one end to extrude the metal from a prescribed die hole to obtain a finished product of the same shape and size. It is mostly used for the production of non-ferrous metal materials.
3. Forging
Forging is a pressure processing method that uses the reciprocating impact of a forging hammer or the pressure of a press to change the blank into the shape and size we require. Generally divided into free forging and die forging, they are often used to produce materials with large cross-sections such as large materials and blanks.
4. Rolling
Rolling is a pressure processing method in which metal blanks are passed through the gap between a pair of rotating rollers (in various shapes). Due to the compression of the rollers, the cross section of the material is reduced and the length is increased. This is the most commonly used production method for producing steel. It is mainly used for Produces profiles, plates and pipes. Divided into cold rolling and hot rolling.
