Cupola is the common type of foundry furnace. This is used for melting cast iron. In Cupola, control over close temperature is very difficult. A Cupola is a shaft furnace of cylindrical shape erected on legs or columns. The Cupola shell is made of steel plate where the interior is lined with refractory bricks to protect the shell from getting over-heated. Here fuel used is coke. This coke and molten metal contact will lead to escape elements like Si and foreign element accumulation may occur. This is really a disadvantage. In crucible or pot furnaces, we can melt ferrous and non-ferrous metals. A disadvantage of these furnaces is the high fuel consumption.
