Description

Technical Field

[0001] The utility model relates to the technical field of heat treatment quenching, in particular to a quenching tank stirring device for heat treatment quenching. Background Art

[0002] The quenching tank is a container filled with quenching medium. When the workpiece is immersed in the tank for cooling, it is necessary to ensure that the workpiece completes the quenching operation evenly at a reasonable cooling speed so that the workpiece meets the technical requirements. For mechanical manufacturing heat treatment, the quenching and tempering heat treatment adopts a mesh belt quenching and tempering production line for batch processing. The workpiece enters the heating chamber in batches and is heated to the required temperature, then enters the cooling chamber to quickly cool in the quenching medium, and finally enters the tempering chamber to heat to the process temperature for a long time of heat preservation and then cools for tempering. Heat treatment refers to the process of heating, heat preservation and cooling of materials in a solid state. Quenching of steel is a heat treatment process in which the steel is heated to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), kept warm for a period of time to make it fully or partially austenitized, and then rapidly cooled to below Ms (or isothermally near Ms) at a cooling rate greater than the critical cooling rate for martensite (or bainite) transformation. The solution treatment of aluminum alloys, copper alloys, titanium alloys, tempered glass and other materials or the heat treatment process with rapid cooling process is usually called quenching.

[0003] In the prior art, the stirring device for the quenching tank for heat treatment quenching also has the following disadvantages:

[0004] The existing quenching tank is equipped with a quenching medium for quenching. The quenching medium assists the quenching work in the quenching box. When the temperature of the quenching medium is uneven, it will cause quenching deformation, cracking and scrapping of metal objects, thereby reducing the practicality of the quenching box. At the same time, some impurities are easily generated during quenching. These impurities settle to the bottom of the quenching box, which is inconvenient to clean and use. Utility Model Content
