[0002] With the development of forging technology, the quality requirements for forgings are getting higher and higher. Especially for the heating temperature of the blank, it is necessary to avoid the situation of insufficient heating temperature or too high heating temperature.

A lower temperature will reduce the forgeability of the material and require greater force to achieve deformation. If the heating temperature is too high or too low, it will lead to poor heat treatment effect and thus affect the product quality. Therefore, it is very important to monitor and control the heating temperature of the blank.
