Coke Fired Cupolas

For many tens of years the coke fired cupola was and in many countries still is the most common furnace for melting cast iron.

The three main reasons why are, the initial capital installation cost is relatively low, the cupola is easy to operate and thus semi skilled labour can be used during the melting operation and the cupola is extremely flexible and is capable of melting many forms of scrap metals from high grades to the very lowest grades and at the same time producing  high quality irons.
