In the smelting process, a stable high-temperature environment needs to be maintained in the furnace, so effective heat preservation measures are crucial. Electroslag remelting furnace ensures temperature stability through various ways, including the use of heat insulation materials and heat preservation measures to reduce heat loss and ensure efficient smelting process.

[0003] Traditional electroslag remelting furnace is usually composed of a smelting furnace body, heating elements, power supply devices and cooling systems. The smelting furnace body is used to contain metal and provide a high-temperature environment, the heating elements are responsible for providing the required heat, and the power supply devices control the current output to ensure the stable operation of the heating elements. The cooling system is used to regulate the temperature of the furnace body to prevent overheating.

[0004] The heat preservation effect of traditional electroslag remelting furnace is not good, mainly due to the selection of heat preservation materials and the ineffective control of heat conduction. Traditional furnace body usually uses a simple heat insulation layer, which fails to fully utilize the advantages of modern heat insulation materials, resulting in easy loss of furnace temperature to the outside. Excessive heat loss not only increases energy consumption, but also makes the temperature unstable during smelting, thereby affecting the smelting efficiency and the final quality of the metal.
