<p>PURPOSE:To rapidly kill the violet foaming of slag by adding metallic Al to foaming slag during the desiliconization of molten iron. CONSTITUTION:Desiliconized slag produced by the desiliconization of molten iron is SiO2 slag contg. iron oxide. When metallic Al is added to the slag, it reacts with the iron oxide in the slag to generate heat remarkably, the salg temp. is raised, and an effect of killing foaming is shown. The reaction product Al2O3 increases remarkably the surface tension of the slag, so the physical properties are improved so that foaming is hardly caused.</p> |
