The four major functions of the annealing furnace, annealing furnace is a very common heat treatment equipment, its main role is to be able to heat the material to a certain program, through the gradual annealing method to reduce the temperature, to avoid the sudden drop in temperature caused by internal damage to the material Or do not achieve the intended purpose. In general, the main function of the annealing furnace is reflected in the following four aspects:

1. Improve or eliminate all kinds of structural defects and residual stress caused by steel during casting, rolling, forging and welding, and avoid deformation and cracking of the workpiece.

2. Prepare the organization for the final heat treatment (quenching, tempering).

3, refine the grain, improve the organization to improve the mechanical properties of the workpiece.

4, soften the workpiece in order to facilitate cutting.
