PRODUCTION OF CEMENT CLINKER

摘要

PURPOSE: To effectively utilize a dephosphorized/desulfurized slag which have been difficult conventionally to use as a part of a cement starting material, etc., and have been disposed. CONSTITUTION: 2-5 pts.wt. dephosphorized/desulfurized slag regulated to <=1000ppm in a chlorine content incorporated in the slug and to <=15wt.% in a granular iron amount by controlling a cooling water for a molten slag generating at desulfurizing stage and dephosphorizing stage as a molten iron pretreatment and a magnetic separation/removal treating condition, is compounded with 140 pts.wt. cement clinker starting material and burned. In this way, the dephosphorized and desulfurized slag can be used as a part of the cement clinker starting material hardly causing influence on compression strength and coagulation of the cement.
