Stainless Steel Slag Conditioning. In trials Valoxy improved the properties of AOD slag from stainless steel production, compared to traditional treatments such as boron. Treatment with Valoxy resulted in a slag with similar micro-hardness, improved chromium entrapment and better microstructure (lower porosity) compared to boron.

The slag in a molten state formed at a step of refining stainless steel is adjusted such that the slag has a basicity in the range of 1.3-4.0, and the slag is mixed with a sulfur-containing material wherein the sulfur is zero or minus in valence, thereby setting the concentration of sulfur in the slag to be not less than 0.2% by weight. The slag is so modified that Cr6+ is substantially ...
