Abstract

The invention relates to the technical field of quenching furnaces, in particular to a vacuum quenching furnace for steel heat treatment, which comprises a furnace body, an electric heating plate is mounted on the inner wall of the furnace body, a feeding hole is formed in the top of the furnace body, the inner wall of the feeding hole is slidably connected with a feeding baffle plate, and the side surface of the feeding baffle plate is connected with the telescopic end of a feeding hydraulic device; the fixed end of the feeding hydraulic device is connected with the side face of the furnace body, a vacuumizing hole is formed in the top of the furnace body, a cooling groove is formed below the furnace body, a material moving mechanism is installed above the furnace body, and the top of the material moving mechanism is connected with the top of the roof. According to the invention, the surface of the workpiece is prevented from being oxidized to form an oxide layer due to contact between the workpiece and air, and potential safety hazards are caused by easy spark splashing during subsequent cooling, and the cooling tank can be protected through the sealing frame, so that the potential safety hazards caused by spark splashing during normal operation are prevented, and the operation safety is improved.
