What are the methods of forging cleaning

Forgings cleaning is the process of removing surface defects of forgings by mechanical or chemical means. In order to improve the surface quality of forgings, improve the cutting conditions of forgings and prevent the surface defects from enlarging, it is required to clean the blank and forgings ...

Defects and Countermeasures of large forgings: Uneven microstructure and properties

Large forgings, due to their large size, many processes, long cycle, non-uniformity in the process, and many unstable factors, often cause serious non-uniformity in the microstructure, so that they cannot pass the mechanical property test, metallographic inspection and non-destructive flaw detect...

Defects and Countermeasures of large forgings: Forging cracks

In large forging, when the quality of raw materials is poor or forging process is not at the right time, forging cracks are often easy to occur. The following introduces several cases of forging crack caused by poor material. (1) Forging cracks caused by ingot defects Most of the ingot defects m... Read More

The forging process of ring forgings

Ring forgings are widely used in industry at present. The forging process of ring forgings is also composed of four parts. The following is mainly to tell you about some ring forging process, I hope you can learn. The forging process of ring forgings mainly consists of the following steps: Pier ... Read More

The basic process of forging

The forging process of forgings is generally as follows: ingots preparation or blank blanking - ingots (blank) inspection - heating - forging - cooling - intermediate inspection - heat treatment - cleaning - final inspection after forging. 1. the ingot is mainly used for the production of medium ...

The influence of various metals on the properties and malleability of steel

Metals are thermoplastic and can be pressed when heated (different metals require different temperatures). This is called malleability. Malleability the ability of a metal material to change shape without cracking during pressure working. It includes the ability to perform hammer forging, rolling... Read More
