Title: Treatment of chromium containing slag
Inventor: YAMAMOTO MASATO
IPC: B09B3/00
Filed: 1996-03-13
Abstract: PROBLEM TO BE SOLVED: To reduce harmful water soluble hexavalent chromium contained in slag to water insoluble trivalent chromium to make harmless the slag with respect to chromium containing slag generated with the heating treatment of melting, welding and autogemous cutting work of steel making materials such as chromium containing alloy steel such as stainless steel, ferrochromium and metal chromium.
