How to prevent heat treatment deformation?
Be sure to keep the temperature of the furnace evenly, and use the station equipment to evenly heat and cool the workpiece. It is strictly prohibited to stack them together. For gears that need to be drilled to reduce weight, the drilling sequence should be arranged after heat treatment. To reduce distortion. The tooth surface induction hardening should use a lower quenching temperature and a shorter heating time, uniform heating, and slow cooling.
With the rapid growth of the national economy,the contradition between the supply and the demand of energy is becoming more and more prominent in China.
