Introduction to the function of annealing furnace (four main functions)

The main function of the annealing furnace is to reduce the temperature of the material heated to a certain program by gradually annealing, so as to prevent the material from internal damage or failure to achieve the expected purpose due to sudden temperature drop. Generally speaking, it is reflected in four aspects

1. Improve or eliminate all kinds of structural defects and residual stress caused by iron and steel in the process of casting, forging, rolling and welding to prevent deformation and cracking of workpiece.

2. Soften the workpiece for cutting.

3. Refine the grain and improve the structure to improve the mechanical properties of the workpiece.

4. Prepare for the final heat treatment (quenching and tempering).
