[0002] As is well known, heat treatment furnace is a general term for industrial furnaces that perform various metal heat treatments on metal workpieces, and it is widely used in the field of heat treatment temperature equalization.

[0003] Nickel alloy bars require heat treatment during processing to reduce hardness, improve machinability, eliminate residual stress, stabilize dimensions, reduce deformation and cracking tendency, refine grains, adjust microstructure, and eliminate microstructural defects.

[0004] However, existing nickel alloy heat treatment furnaces have a simple structure. After the nickel alloy bars are placed inside the furnace, they remain stationary, which makes it difficult to achieve uniformity during the heat treatment of the nickel alloy bars and results in low heat treatment efficiency. Utility Model Content

[0012] For ease of use, as a preferred embodiment of this utility model of a nickel alloy heat treatment furnace that facilitates temperature control, the front end face of the furnace body is provided with a door.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] The motor is started, which drives the second gear to rotate. The second gear drives the first gear to rotate, and the first gear drives the rotating rod and shaft to rotate.
