摘　　要：在转炉炼钢过程中,针对出钢脱氧合金化操作中合金加入量的确定问题,提出了基于收得率预测模型的转炉炼钢合金加入量计算方法。首先使用支持向量机,建立了出钢合金化过程的合金收得率预测模型,进而利用预测结果计算合金加入量。使用实际生产数据进行仿真,结果表明该方法能够准确计算出合金加入量,符合实际生产的要求。In the process of BOF steelmaking in order to figure out the reasonable amount of alloy addition during deoxidizing and alloying of tapping, the predicting model for alloying yield of tapping is developed based on the knowledge of alloying yield, sup- port vector machine is used to build up an alloy yield prediction model, and then the pre- dicted results are used to calculate the amount of alloy addition. In the study simulation is carried out with the practical production data. Results shows that the alloy addition calculating model of BOF based on predicting yield is up to the mustard of practical manufacturing.
