SHAPE CONTROL APPARATUS FOR SOLIDIFIED SLAG, SHAPE CONTROL METHOD FOR SOLIDIFIED SLAG, AND SOLIDIFIED SLAG

摘要

PROBLEM TO BE SOLVED: To obtain slag solidified in such a shape as to yield slag aggregate having a proper shape and a proper grain size distribution after crushing at a low cost, without increasing the solidification thickness of slag beyond necessity.SOLUTION: Different rugged shapes are separately provided to the upper and lower surfaces of solidified slag formed by pouring slag from a blast furnace into a continuously conveyed casting mold. Whereby, since a targeted grain size distribution of slag aggregate can be directly made while suppressing thermal load applied to the casting mold, slag solidified in such a shape as to yield slag aggregate having a proper shape and a proper grain size distribution after crushing at a low cost can be obtained, without increasing the solidification thickness of slag beyond necessity.
