Special heat treatment furnace for vertical mandrel

The utility model provides a vertical mandrel dedicated heat treatment furnace, including: base, track, induction door, furnace body, controller, temperature sensor and manipulator, the middle of base is provided with furnace body, the controller is installed the right side of furnace body front surface. Due to the design of a temperature buffer zone and a partition plate between the constant-temperature chamber and the cooling chamber, after a mandrel enters the transition chamber from the constant-temperature chamber, due to the fact that a large amount of heat energy is dissipated by the mandrel, the heat energy can be gathered to the left side and the right side of the partition plate respectively, and a temperature slow-decreasing area is formed in cooperation with the partition plate; high-temperature heat in the constant-temperature chamber is prevented from quickly entering the cooling chamber, so that the constant-temperature chamber can keep constant temperature without increasing energy consumption
