Furnaces, Electric, Resistance Furnaces - Kirk-Othmer
The term oven should be used when temperatures are below 760°C, and the word furnace applied for higher temperatures. Electric furnaces are used for annealing, brazing, carburizing, galvanizing, forging, hardening, melting, sintering, enameling, and tempering metals, most notably aluminum, copper, iron and steel, and magnesium alloys.
