Abstract
A method for improving the characteristics of fused slag material is disclosed. This improved method results in a fused slag having resistance against pulverization at the cooling process or generation of yellowish turbid water due to contact of slag lumps with rain water, this method characterized by forming a slag treatment material by rough crushing a substantially dehydrated heat-treated material containing boron, and adding that slag treatment material to molten slag.
