In the conventional heat treatment process, the shape change of the parts is mainly completed by the heating and quenching of the heat treatment. The heating speed is very fast. Compared with the traditional heating furnace, the parts are relatively large. The cooling rate of different parts is different, and a thermal stress will appear to deform the part. Next, let's talk about how to prevent the deformation of the gas spring during the heat treatment process.
During the heat treatment of forgings, hang the gas spring as vertically as possible and place it at the bottom of the furnace. The third is to use two points for horizontal support.
