Since the discovery of the thermal effect of electric current (the Lenz-Joule law), the electrothermal method was first used in household appliances and later in small electric furnaces in laboratories. With the invention of nickel-chromium alloys, resistance furnaces have been widely used in industry by the 1920s. The resistance furnace used in industry is generally composed of electric heating elements, masonry, metal shell, furnace door, furnace machinery and electrical control system. The heating power ranges from less than one kilowatt to several thousand kilowatts. The operating temperature is below 650 degree for low temperature furnace; 650-1000 degree is for medium temperature furnace; above 1000 degree is for high temperature furnace. In the high temperature and medium temperature furnace, heating is mainly done by radiation. In the low-temperature furnace, it is heated by convective heat transfer. The electric heating element is installed in the air duct, and the gas in the furnace is forced to circulate through the fan to enhance the convective heat transfer. Resistance furnaces include chamber type, well type, trolley type, push rod type, stepping type, muffle type and tunnel type. Controllable atmosphere furnaces, vacuum furnaces, flowing particle furnaces, etc. are also resistance furnaces.
