Title: Reforming treatment of stainless steel refining slag
Inventor: MATSUNAGA HISAHIRO
IPC: C21C5/00
Filed: 2000-02-07
Abstract: PROBLEM TO BE SOLVED: To completely prevent the elution of Cr6+ from the molten slag which contains the chromium oxide generated at the time of refining of stainless steel and has basicity within a specific range and to effectively utilize the slag as roadbed materials and civil engineering landfilling materials without the possibility of environmental contamination by adding a sulfur-containing material having a specific valence into the molten slag in such a manner that its sulfur concentration attains a specific ratio or above. SOLUTION: The basicity of the molten slag is 1.3 to 4.0 and the sulfur- containing material having zero or minus valence is added to the molten slag in such a manner that the sulfur concn. therein attains 0.2 mass%. The time for the addition of the sulfur-containing material is preferably at the time of the molten state after the end of reduction refining when the flow property of the slag is high after the end of refining before the solidification of the slag. The diffusion of the sulfur compound into the slag is made possible by adding a boron compound-containing material to the slag and the powdering at the time of slag cooling is prevented as well. The B2O3 concentration in the slag is preferably >=0.1 wt.%. The Cr6+ does not elute even in the case of slag of a high chromium concentration exceeding 2.5 wt.% in the Cr content.
