An electric furnace uses electrical resistance as a heat source to produce high temperatures. Several kinds of heat-resistant materials are used in their construction. An enclosed space holds the materials, gas, or air being heated until the desired temperature, which is measured by an external sensor.
.
Electric furnaces can have varying temperatures or a single one. To increase heating, coal and oxygen can be added. They normally have atmospheres that can include air or oxidizing, inert, reducing, salt bath or vacuum and come in three or multi-zone varieties. Over-temperature protection, service or entry holes, viewports, computer interface and application software are available options. A common type of electric furnace is the electric arc furnace, which is used for making steel from scrap materials.
.
A benefit of electric furnaces is the precision control of their temperature and internal atmosphere. Important factors to consider when selecting an electric furnace are pressure range, process temperature, chamber length, and the height, width, or tube outer diameter of the furnace. Pressure range is the furnace's operating pressure, and temperature is the furnace operating temperature.
