Abstract
PURPOSE: To eliminate the need for discarding of desulfurization slag, utilize the Ca components in the desulfurization slag and provide the effect of killing two birds with one stone by making up the defficiency of the dephophorization components in blast furnace slag with the desulfurization slag obtained at the time of desulfurizing the molten iron with Ca compounds.
CONSTITUTION: Molten iron A from a blast furnace 1 is charged into a dephosphorizing pan 2, and a dephosphorizer D is added thereto, by which the molten iron is dephosphorized and the formed dephosphorization slag is discarded. The dephosphorized molten iron is added with CaC2 on a mixer car 3, and is thereby desulfurized, after which it is treated in a converter 4. On the other hand, the blast furnace slag B is conducted to a slag making pan 5, where it is mixed with the desulfurization slag C discharged in said desulfurization process, whereby said dephosphorizer D is produced.
