The heat treatment process of quenching and tempering 60Ti steel screws using medium frequency induction heating equipment

As an important part of the automobile, the screw must withstand huge friction during work. Therefore, the screw is required to have high hardness, wear resistance and service life. We usually use medium frequency induction heating equipment to heat treat the screw. Today, the technical staff of Zhengzhou Gou's will briefly introduce the heat treatment process of the screw.

1. Induction quenching of 60Ti steel screw

The heating equipment is medium frequency induction heating equipment and horizontal quenching machine tool, and the quenching medium is tap water. The deep induction heating surface quenching process is adopted, the selected specific power is 0.32kW/cmz, and the quenching cooling spray degree is 0.07L/(cm2·s). The quenching process parameters are as follows:

2. Low temperature tempering and spline induction tempering of 60Ti steel screw

In order to ensure the stability of the surface structure and hardness of the screw after induction quenching, medium-low temperature tempering in a heating furnace is used, 150°C × 1.5h. According to the product technical requirements, the surface hardness of the screw spline part is 36-45HRC. In order to reduce the hardness of this part after quenching, a local surface induction heating and tempering process is adopted, and the inductor is in the form of a circular ring structure. The process parameters of surface induction tempering of screw spline parts are as follows:
