resistance furnace
Quick Summary
A resistance furnace is a type of electric furnace that generates heat from the energy lost by a resistor. In this furnace, electricity is used as the heat source to achieve very high temperatures, primarily for melting and alloying metals and refractories.12
There are a couple of ways a resistance furnace operates:
* The material being heated, known as the furnace charge, can itself act as the resistance element.2
* Alternatively, heat-producing current can be introduced through electrodes that are buried within the material.2
* In some designs, resistance elements line the interior walls of the furnace.2
Resistance furnaces are still utilized in the production of materials like silicon carbide and in electrolytic aluminum processes.2
