Description

Technical Field

[0001] The present invention relates to the technical field of heat treatment, and particularly relates to a workpiece heat treatment device. Background Art

[0002] Heat treatment refers to a metal hot working process in which materials are heated, held, and cooled in the solid state to obtain the desired microstructure and properties.

[0003] Quenching is a heat treatment process. Quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), hold for a period of time to make it fully or partially austenitized, and then rapidly cool to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate for martensite (or bainite) transformation. Usually, the solution treatment of materials such as aluminum alloys, copper alloys, titanium alloys, and tempered glass, or the heat treatment process with a rapid cooling process, is also called quenching.

[0004] During the quenching process, quenching oil is usually used to rapidly cool high-temperature workpieces. However, during the use of quenching oil, the phenomenon of excessive temperature of the quenching oil is likely to occur. Due to the excessive temperature of the quenching oil, it is easy to cause the quenching oil to age rapidly, and when the quenching oil with too high a temperature quenches the workpiece, it affects the cooling effect and is likely to affect the hardenability and through-hardening ability of the quenching oil.
