以冶金含铁尘泥为原料,以尘泥中的碳作为还原剂,添加粘结剂,用对辊压球的冷固结方法制成具有自还原特性的尘泥球团,球团中的碳与铁氧化物紧密接触,在转炉内利用转炉热环境使其中的铁氧化物实现还原回收而不影响钢铁冶炼生产,解决了不使用任何专用还原设备快速高效回收铁的难题。达到废钢的冷却效果,从而代替部分废钢,开辟了冶金废料利用新途径。实现以“废料—炼钢”的低能耗小循环取代“废料—烧结—炼铁—炼钢”大循环,经济效益显著,有很好推广价值。
The metallurgical iron-containing dust as raw material, the carbon dust in the dust as a reducing agent, adding a binder, with the pressure of the ball on the cold consolidation method made of dust with self-reduction characteristics of the ball, the pellet Carbon and iron oxide in close contact with the converter in the converter thermal environment so that the iron oxide reduction and recovery without affecting the production of steel smelting and solve the problem without using any special reduction equipment quickly and efficiently recover iron. Achieve the cooling effect of scrap, thereby replacing part of the scrap, opened up a new way for the utilization of metallurgical waste. Achieve “scrap - steel ” low-power small cycle to replace “scrap - sintering - ironmaking - steel ” cycle, significant economic benefits, there is a good promotional value.
