| titleOfInvention | Method for melting calcium aluminate by synchronously activating, inerting, impurity removing and low-magnesium aluminum ash |
| abstract | The invention discloses a method for melting calcium aluminate by synchronously activating, inerting, impurity removing and roasting low-magnesium aluminum ash, which comprises the following steps of carrying out wet ball milling on a mixed raw material of the low-magnesium aluminum ash and a calcium-containing additive, and sequentially carrying out solid-liquid separation, drying and roasting on ball-milled materials to obtain a calcium aluminate product; the method takes low-magnesium aluminum ash slag generated in the aluminum smelting process as a raw material to prepare the calcium aluminate product which can be used for steel smelting desulphurization, not only realizes the comprehensive utilization of dangerous waste, but also can obtain higher economic value, and the method has the advantages of simple operation, low cost, environmental friendliness and meeting the requirement of industrial production. |
