METHOD OF DE-CHROMING AND/OR DEPLETING THE MgO CONTENT OF STEEL SLAG |
摘要 |
The invention concerns a method of de-chroming steel slag, oxygen being introduced into the liquid steel slag in an amount sufficient to convert iron quantitatively into iron oxide and at least 5 wt % of the iron oxide present in the slag into iron-III oxide. The resultant oxidized slag is hardened and comminuted, the paramagnetic portions formed then being separated magnetically and dissociated from the de-chromed slag. |
