The present invention relates to a method for reduction of chromium content in slag during melting of stainless steel in electric arc furnaces where steel scrap and additive alloys are melted in an electric steel furnace, whereafter molten steel and slag are tapped into a ladle, removal of the slag from the steel in the ladle, transferring of the molten steel from the ladle to a converter wherein the steel is refined and where the chemical composition of the steel is adjusted by addition of alloying elements. According to the invention fine particulate ferrosilicon is added to the slag during the time interval between the slag and the steel are melted, but before the molten steel and slag is tapped into the ladle. |
