Electrical operation is the most basic guarantee for electric furnace steelmaking

Industrial electric furnaces are widely used in the industrial field, and salt bath electric furnaces are also a type of industrial electric furnaces. Salt bath electric furnaces use molten salt solution as the heating medium to immerse the workpiece in the salt solution for heating
The steam of the heating medium in salt bath electric furnaces is harmful to human health and must be ventilated when used. Salt bath electric furnaces are divided into two categories: internal heating and external heating. Internal heating salt bath electric furnaces are also divided into electrode salt bath electric furnaces and electric heating element salt bath electric furnaces
The heating speed of salt bath electric furnace is fast and the temperature is uniform. The workpiece is always heated in the salt solution, and there is a layer of salt film on the surface of the workpiece when it is discharged from the furnace, which can prevent oxidation and decarburization of the workpiece surface. Salt bath electric furnace can be used for quenching, annealing, tempering, cyanide, aging and other heat treatment tube furnace heating of carbon steel, alloy steel, tool steel, box furnace mold steel, and aluminum alloy, and can also be used for less oxidation heating during precision forging of steel
According to the working temperature of a tubular electric furnace, salts such as sodium chloride, potassium chloride, barium chloride, sodium cyanide, potassium cyanide, sodium nitrate, potassium nitrate, etc. are usually selected as the heating medium
