[0002] Heat treatment refers to a metal thermal processing technology that changes the chemical composition and structure of the surface or interior of the material by heating, keeping warm and cooling the metal material in the solid state to obtain the desired properties.

[0003] The existing patent (announcement number: CN209098740U) discloses a heat treatment device for the production of metal steel castings, including a heat treatment box, an air pump, a second conduit and a spray plate. A protective door is hingedly installed on the front of the heat treatment box. An air pump is fixedly installed at a position near the upper end on the left side of the heat treatment box, and a first conduit is fixedly installed at the output end of the air pump. A second conduit is fixedly installed at the input end of the air pump, and the end of the second conduit away from the air pump passes through the heat treatment box, and the second conduit extends to the outer surface of the inner wall on the left side of the heat treatment box. The utility model device is designed in combination with traditional cooling methods when used. The cooling work is carried out by using a dual combination of water spraying and air cooling, so that the cooling effect of the entire device is higher, and the oxidation and decarburization of parts are reduced, the protective heat insulation effect of the entire device is improved, and the situation of burns caused by excessive temperature is prevented. In addition, the device has a novel and rich structure and diverse functions.

[0004] When the above device is in use, the staff places the parts to be heated on the placement rack, and then manually slides the fixed pressure plate downward in the slide groove through the slider, so that the fixed pressure plate is tightly against the parts, and fixes it by manually tightening the fixing screws. However, during use, for some materials with larger mass, due to the limitation of the internal space of the heat treatment box, it is not convenient for users to carry, place and fix them.

During operation, it is easy to scald the staff, which is more inconvenient. In addition, during the use of the above device, it is impossible to collect and recycle the used cooling water, which wastes cooling water. Utility Model Content
