Application

It can effectively improve the defects and residual stress in the process of casting, forging, rolling or welding, and prevent the deformation and cracking of the workpiece;

The annealing furnace can also soften the workpiece for cutting and machining;

The mechanical properties of the workpiece are improved by refining the grain and improving the microstructure;

It can be prepared for the final heat treatment of quenching and tempering points.
