METHOD OF MANUFACTURING GRANULAR MOLD FLUX USING LIQUID FREE CARBON, AND APPARATUS FOR MANUFACTURING AND SUPPLYING LIQUID FREE CARBON

摘要

PROBLEM TO BE SOLVED: To provide the new technique where the charging method of free carbon is renewed in a method of manufacturing granular mold flux so as to improve the dispersibility of free carbon in a product, wherein, by developing a method in which, upon manufacture of a suspension during the conventional granular mold flux manufacturing process, particulate free carbon is charged in a liquid state, the free carbon in the manufacture is uniformly distributed compared with the conventional manufacturing method.;SOLUTION: Regarding the apparatus and method where, in a process for manufacturing granular mold flux as by-product materials charged to the upper part of a molten steel within a mold in a continuous casting stage for steel, free carbon is charged in a liquid state upon manufacture of a suspension, the apparatus and method are applied to a continuous casting process, and uniform warm keeping effect is exhibited, thus they have the effects of improving the quality of a solidified slab as an intermediate finished product and solving the overgrowth problem of a slag bear which can be made into the cause of an operational problem.;COPYRIGHT: (C)2010,JPO&INPIT
