【摘要】 研究了MgO对烧结工艺及烧结矿冶金性能的影响。研究结果表明,在烧结过程中不加或少加MgO,可提高烧结生产效率,获得冷态强度高、软熔带温度区间窄的烧结矿,从而提高高炉软熔带的透气性、降低料柱全压差。为保证高炉渣对MgO含量的要求,以及确保烧结矿低的低温还原粉化率,提出了合理添加MgO的新工艺。更多还原

【Abstract】 Based on laboratory experiments,the effects of MgO on sintering process and metallurgical properties of sinter are examined.The results show that without or with small amount of MgO in burden,the sintering productivity can be improved,and the sinters have high cold strength and narrow temperature range of cohesive zone.Consequently,the permeability of cohesive zone in blast furnace can be improved and the total pressure drop in blast furnace can be decreased by use of such sinters.In order to ensure proper MgO content in the BF slag and improve the RDI of sinter,a new process of adding MgO in BF is proposed.更多还原
