Abstract

When steel smelted in a basic oxygen converter at an increased specific hot iron consumption rate of 950 kg/t and over, the slag formation process proceeds with deviations from the specified oxygen-lancing conditions under viscous slag formation during the converter turndown. Solutions are proposed to normalize the slag formation including dissolution of lime. This allows stabilizing of the slagging and lancing conditions, as well as preventing long downtimes of the equipment.

铁矿石球团冶炼转炉熔渣实践的改进

摘要

当在碱性氧气转炉中以增加的比热铁消耗速率950 kg / t或更高的速度冶炼钢时，在转炉调低期间，在粘渣形成过程中，炉渣的形成过程会偏离指定的氧气喷枪条件。提出了解决方案以规范包括石灰溶解在内的炉渣形成。这样可以稳定排渣和切缝条件，并防止设备长时间停机。
