Abstract

The CO2 which is pref. liq. is introduced into the molten metal leaving a blast furnace, e.g. in a ladle using an injection lance immersed in the molten metal. Before plunging the lance into the molten metal, it is energetically cooled pref. by circulating liq. CO2 through it until it becomes frosted.
