[0002] Metal heat treatment is a process in which a metal or alloy workpiece is heated to a suitable temperature in a certain medium, kept at this temperature for a certain period of time, and then cooled at different speeds in different media to control its performance by changing the microstructure of the surface or interior of the metal material. Among them, quenching is a common heat treatment process. Quenching is a heat treatment process in which steel is heated to above the critical temperature, kept at this temperature for a certain period of time, and then cooled at a cooling rate greater than the critical cooling rate to obtain an unbalanced structure dominated by martensite (bainite can also be obtained or single-phase austenite can be maintained as needed). Quenching is the most widely used process in steel heat treatment.

At this time, it needs to be quickly put into the quenching pool for rapid cooling with quenching oil. However, when the workpiece enters the oil, the oil close to the workpiece will boil. At this time, the oil will splash out and cause harm to the operator. Therefore, a metal material heat treatment device with a protective function is proposed to solve the above problems.
