Abstract
In a process for producing cast iron in various grades of different carbon contents, a cast iron grade of a defined charge make-up, essentially consisting of defined proportions of iron, coke and limestone, is produced. A different cast iron grade requires a charge of correspondingly different composition. To make the operation of a cupola furnace more flexible, carbon-containing material is introduced into the cupola furnace in the form of dust to influence the carbon content of the iron produced, namely in a quantity depending on the carbon content of the cast iron grade to be produced.
