[0002] The crushing wall, jaw plate and other parts of the cone crusher are all made of high manganese steel, so it is necessary to heat treat the high manganese steel to change the metallographic structure and improve the wear resistance.
[0003] Generally speaking, a heat treatment machine is a device that changes the internal structure of a material by heating, keeping it warm, and cooling it to obtain the desired performance.
[0004] Its basic working principle mainly includes the following key steps:
[0005] The first is the heating stage. The heat treatment machine uses various heating methods, such as resistance heating, induction heating, flame heating, salt bath heating, etc., to quickly heat the workpiece to a predetermined temperature.
[0006] For example, in resistance heating, current flows through a resistance wire to generate heat, which is transferred to the workpiece; induction heating uses the principle of electromagnetic induction to generate eddy currents inside the workpiece, thereby generating heat.
[0007] Then comes the holding stage. After reaching the set temperature, the workpiece needs to be kept at that temperature for a certain period of time to allow the internal structure transformation of the material to proceed fully. The length of the holding time depends on the type of material, the size of the workpiece, and the purpose of the heat treatment.
[0008] The gap between the furnace door and the furnace body of the heat treatment machine will cause heat loss and outside air to enter the furnace. The outside of the furnace door is at high temperature, which can easily cause scalding accidents. Utility Model Content
[0009] The purpose of the utility model is to provide a heat treatment machine with excellent thermal insulation performance to solve the defects mentioned in the above background technology.

[0011] Preferably, guide seats are fixedly installed at both ends of the sealing door body, and the sizes of the guide seats are adapted to those of the guide grooves, and the guide seats are slidably arranged inside the guide grooves.
[0012] Preferably, the guide seats at both ends of the sealing door body are internally threaded with mounting screws, and the two groups of screws are driven to rotate by two groups of synchronously moving driving motors respectively, and reinforcing ribs are fixedly provided on the surface of the sealing door body.
[0013] Preferably, a plug-in slot is provided at the bottom of the fixing seat, and the plug-in slot at the bottom of the fixing seat covers the top of the two sets of limiting rails and is fixed by bolts.
[0014] Preferably, positioning grooves are provided on both sides of the surface of the sealing door body, and the positioning grooves are adapted to the size of the positioning blocks. At the same time, the positioning blocks are inserted into the inside of the positioning grooves, and the positioning blocks are arranged in four groups and are evenly fixed on the back side of the first thermal insulation sheet. The bottom of the sealing door body moves downward and is clamped inside the sealing port opened on the surface of the bottom plate of the furnace mouth.
[0015] Preferably, the areas of the first thermal insulation sheet and the second thermal insulation sheet are consistent, and multiple groups of heat dissipation holes are evenly opened on the surfaces of the first thermal insulation sheet and the second thermal insulation sheet. Meanwhile, the first thermal insulation sheet is a ceramic fiber partition, and the second thermal insulation sheet is an asbestos partition.
[0016] Compared with the prior art, the beneficial effects of the utility model are:

At the same time, the guide seats at both ends of the sealing door body are slidably arranged inside the guide groove to ensure that the sealing door body can effectively prevent heat loss and outside air from entering the furnace when it is closed, and increase the flatness and fit of the sealing contact surface. Good sealing can reduce energy consumption and improve the efficiency and quality of heat treatment.
[0018] The surface of the sealed door body is covered with a first insulation sheet and a second insulation sheet respectively, which can insulate the high-temperature sealed door body to reduce the temperature loss on the surface of the furnace door, reduce the risk of scalding for operators when they touch the furnace door, and reduce the heat transfer to the outside.
