[0002] With the development of alloy production equipment, the requirements for heating technology are getting higher and higher. The existing spiral coil heater is not convenient for subsequent maintenance of the internal body of the device, which is easy to cause aging failure of the shell. This device proposes a device that can facilitate subsequent maintenance of the internal body of the device, has good sealing in a fixed state, can protect the device, and can prevent the aging failure of the shell caused by excessive residual temperature generated by the outer wall of the spiral coil of the device body. The spiral coil heater with stronger placement stability can solve the problem of inconvenience for subsequent maintenance of the internal body of the device, which is easy to cause aging failure of the shell.

[0003] The Chinese utility model with authorization announcement number CN219248094U discloses a new type of disc heater. When in use, the armor heating wire is coiled into a spiral shape and installed in the heating disc body to increase the heat conduction area. Combined with heat-conductive fillers, it is beneficial to heat conduction. The device requires the heated object to be placed on the heating disc for heating, and utilizes the characteristics of physical heat conduction to conduct the temperature to the bottom of the object to be heated through the heating disc, and then the bottom of the object is heated and the temperature is transferred to the entire object. This heating method will cause the local temperature of the surface in contact with the heating disc to be too high, which poses certain safety hazards. Therefore, it is necessary to redesign the disc heater to address the above problems. Utility Model Content
