There are several types of casting furnaces which include Electric Arc furnaces, Blast furnaces, Cornwall Iron Furnace, etc. The electric arc furnace can be described as a furnace heating charged materials by the way of an electric arc. The Blast Furnace can be referred to as a kind of metallurgical furnace, through which the process of smelting takes place.
Blast Furnaces produce metals, normally iron. These furnaces trace their origin to China (around 500 BC). Electric Arc furnaces exist in all the sizes-right, from the smallest one having a capacity of around 1 ton to the largest one having a capacity of 400 tons. The former one is used in foundries to produce cast iron products, whereas the latter one is used for secondary steel making.
