PROCESS FOR REDUCING THE IRON CONTENT OF CAO-RICH SLAGS FORMED DURING THE DESULPHURISATION OF CRUDE IRON

摘要

AbstractThe invention relates to a process for reducing the iron contentof CaO-rich slags formed during the desulphurisation of crude iron. Accordingto the invention, finely-ground fluorspar is added to the melt, in the ladle,in an amount such that a significant reduction in the iron content of theslag occurs, but that the slag is not rendered fluid.
