[0002] A high-temperature heat treatment electric furnace is a type of equipment widely used in industrial production. It is mainly used for high-temperature treatment of materials, such as normalizing, quenching, annealing and other heat treatment processes, or for high-temperature sintering of cutting blades such as diamonds. This type of electric furnace is an energy-saving cycle operation electric furnace that meets national standards. It has high temperature control accuracy and can meet the needs of various high-precision heat treatment processes. There are many types of high-temperature heat treatment electric furnaces, such as box-type electric furnaces, energy-saving box-type electric furnaces, etc. These electric furnaces are different in structure, but the common point is that they all provide heat sources through electric heating to perform high-temperature treatment on the materials in the furnace.
