<p><P>PROBLEM TO BE SOLVED: To provide an inhibitor for the dusting of steel making slag which can suppress the dusting of steel making slag with a low boron content. <P>SOLUTION: The inhibitor essentially consists of a magnesium-containing compound to be a feed source of magnesia in steel making slag in a molten state, and boric acid or a boron-containing compound to be a feed source of boric acid in steel making slag in a molten state. The boron-containing compound can be any one or a combination of two or more kinds selected from colemanite ulexite, tincal, and kernite. The magnesium-containing compound can be any one or a combination of two or more kinds selected form magnesia- based glass, dolomite, carnallite and magnesite having a magnesia content of 24 to 26 wt.%, and the balance essentially alumina and silica. <P>COPYRIGHT: (C)2003,JPO</p> |
