Difference between Submerged Arc Furnace and Electric Arc Furnace

What is the difference between submerged arc furnace and electric arc furnace? The submerged arc furnace is a kind of electric arc furnace.
Design of Submerged Arc Furnace

The design of submerged arc furnace is mainly used for reducing and smelting ores, carbonaceous reducing agents, solvents, and other raw materials. It mainly produces ferrosilicon, ferromanganese, ferrochrome, ferrotungsten, silicomanganese, and other ferroalloys, which are important industrial raw materials in the metallurgical industry and chemical raw materials such as calcium carbide.
