[0002] Heat treatment refers to a metal thermal processing process in which the material is heated, kept warm and cooled in the solid state to obtain the expected structure and properties.

[0003] A high-efficiency heat treatment structure for improving the hardness of low-alloy steel castings with a publication number of CN219079575U has been retrieved, comprising a base, four telescopic rods fixedly mounted on the upper surface of the heating box, a telescopic motor fixedly mounted on the outer surface above the four telescopic rods, a transmission motor fixedly mounted on the outer surface of the front side of the heating box, a plurality of heat dissipation ports provided on the outer surface of the front side of the transmission motor, and a wiring tube inserted on the right side of the transmission motor. The high-efficiency heat treatment structure for improving the hardness of low-alloy steel castings has a heating box fixedly welded on the upper surface of the base, and high-temperature heating tubes fixedly mounted on the outer surfaces of both sides of the heating box. The high-temperature heating tubes are in a linear array, so that the alloy steel castings can be fixed inside the heating box through a partition and heated at high temperature in a small space through the high-temperature heating tubes on both sides, thereby achieving all-round heating of the alloy steel castings, greatly improving the heating efficiency of the high-efficiency heat treatment structure for alloy steel castings.
