A mixture of a metal oxide and carbon is introduced into a furnace and foamed on a high chromium melt in an electric arc furnace, which foams the slag by forming bubbles in the slag with a gas produced by reducing the metal oxide by carbon in the slag. In the method of producing slag, it is intended to be able to control the gas generation and thus the slag foaming process. To that end, a mixture of metal oxide and carbon is introduced into the furnace as a preformed member, such as pellets, which are compressed and / or have a binder. By adjusting the properties of the pellets, in particular the density and / or compression properties, it is possible to control the gas evolution in position, type and time. |
