用原生精矿、石灰石粉、富矿和20～25%的轧钢皮、<7.5%的焦粉,能够生产出基本上合乎要求的平炉烧结矿,在工艺流程上是可能的;但由于转运10次,烧结矿的破碎很严重。为了正常生产,有必要考虑新的运输方案。通过冶炼试验,证明在平炉装料期部份或全部使用烧结矿是可行的,降低了石灰石用量约15～38%,冶炼操作基本顺利,对钢质没有影响。
With primary concentrate, limestone powder, rich ore and 20-25% of rolled steel, <7.5% coke powder, it is possible to produce essentially desirable open hearth sintered ore in process flow; however, due to the 10 times of transfer , The crushing of sinter is very serious. For normal production, it is necessary to consider the new transportation scheme. Through the smelting test, it is proved that it is feasible to use some or all of the sinter in the open hearth charging period, reducing the limestone dosage by 15-38%. The smelting operation is basically smooth with no influence on the steel quality.
