| titleOfInvention | Chromium-containing slag treatment method |
| abstract | (57) [Summary] (Corrected) [Problem] Melting of chromium-containing alloy steel such as stainless steel, steel-making materials such as ferrochrome and metallic chromium. welding. About the chromium-containing slag that is generated with the heat treatment of the fusing work, The purpose is to reduce harmful water-soluble hexavalent chromium contained in the slag to water-insoluble trivalent chromium to render the slag harmless. SOLUTION: Chromium-containing slag generated by heat treatment such as melting, rolling, welding, and fusing of chromium-containing alloy steel such as stainless steel, ferrochrome, metallic chromium, etc. is crushed or crushed to the surface thereof. On the other hand, by spraying or dipping a solution containing one or more of ascorbic acid or a metal salt or ammonium salt of ascorbic acid, the hexavalent chromium contained in the slag is reduced to trivalent chromium and harmless. A method for treating a chromium-containing slag, which is characterized in that the slag is treated in a stable manner so that the slag can be treated safely after the slag. |
