[0002] An electric fused magnesium furnace is an electric furnace that uses the heat of an electric arc to melt metals, primarily for melting magnesium materials. Its working principle involves generating an electric arc using an electric current, converting electrical energy into heat energy, thereby heating and melting the metal and slag. Electric fused magnesium furnaces typically employ a submerged arc design, featuring high temperature, low energy loss, and fast reaction speed, enabling high-purity and high-efficiency manufacturing.
