[0002] Heat treatment is a key process in gear forging. By controlling the heating, insulation and cooling processes, the internal structure of the material is changed to achieve performance optimization.

[0003] However, the ventilation efficiency of existing heat treatment equipment for gear forging is low, which means insufficient oxygen supply and incomplete combustion of gas, resulting in incomplete combustion products such as carbon monoxide. This not only pollutes the environment, but also leads to uneven heating and energy waste. In addition, uneven heating will affect the heat treatment effect of gear materials, reducing product quality and production efficiency.

[0004] Therefore, in view of the problem that the existing heat treatment device for gear forging has low boiler air ventilation efficiency, resulting in insufficient combustion of gas heating and uneven heating and energy waste, a heat treatment device for gear forging can be designed.
