摘要
转炉炼钢环节当中，渣量控制对于整个炼钢过程中的成本影响较大。莱铜炼铜厂新区由于低磷品种钢的产量比例高，生产过程中为保证铜水质量，石灰加入量较多，同时由于铁水条件波动造成终点控制不稳定，以上因素导致目前总渣量控制偏高。通过对转炉操作模型进行优化，研究转炉留渣操作模型，优化双渣冶炼生产工艺，减少转炉入炉渣料，降低转炉渣量。通过制定转炉终点控制标准，优化底吹模型，提高复吹转炉终点控制的稳定性。
The impact on the cost is bigger in the whole process of steehnaking which brought by the slag quantity control. Due to low phosphorus steel production rate is high, lime addition amount is more in the production process to ensure the quality of molten steel. At the same time caused by molten iron fluctuation end point control is not stable, the above factors lead to total slag volume control on the high side. By optimizing model of converter operation, the converter slag operation model, optimization of double slag smelting production process, reduce the converter slag material, thereby reducing slag quantity. Through the formulation of converter end point control standards, optimization model of bottom blowing, improve the stability of the combined-blowing converter end point control.
