PROCEDIMIENTO PARA REDUCIR EL CONTENIDO DE HIERRO DE LAS ESCORIAS RICAS EN CAO QUE SE PRODUCEN DURANTE LA DESULFURACION DE ARRABIO.

摘要

A process is described and claimed for reducing the iron content of a CaO-rich slag which is formed during the desulphurization of molten crude iron which comprises adding finely-ground fluorspar to the melt, in the ladle, or adding it to the lade prior to adding the crude iron thereto, in an amount such that the slag is not rendered fluid.
