电硅热法中、低碳铬铁生产过程中产生大量铬渣,铬渣中含有一定数量的铬铁。过去,我厂上述渣中的铬铁一直没有很好的方法进行回收,而是随着铬渣一起排入渣山,造成很大的损失。根据这种情况,我们研制了一套回收渣中铁的设备,采用先筛分后磁 In the electric silicon thermal method, a large amount of chromium slag is produced during the production of low-carbon ferrochromium, and the chromium slag contains a certain amount of ferrochrome. In the past, the ferrochromium in the above slag of our plant has not been recovered in a very good way, but it has caused great losses as chrome slag discharged into the slag mountain together. According to this situation, we have developed a set of equipment for the recovery of iron slag, using the first screening of the magnetic
