I. Introduction to annealing process:

Annealing is a heat treatment method of metal materials in which the metal materials are slowly warmed to a certain temperature, maintained for a good time, and then cooled at a suitable rate, sometimes naturally, sometimes at a controlled rate.

 Ii. Target of annealing:

1. Reduce the strength, soften the workpiece, and improve the drilling process performance.

2. Improve or remove various mechanism defects and internal stress caused by steel in the whole process of forging, casting, cold rolling and electric welding, and reduce the tendency of workpiece deformation, cracking or cracking.

3. Optimize the crystal, improve the mechanism to improve the physical properties of the product workpiece, and remove the defects of the mechanism.

4. Symmetrical the raw material mechanism and composition, improve the characteristics of the raw material or prepare the mechanism in advance for later tempering treatment, such as annealing and tempering.

In the specific production and manufacturing, annealing process is very common, according to the workpiece quenching target is different, quenching and tempering treatment has a variety of processing technology, common quenching, spheroidizing annealing, stress quenching and so on.
