摘　　要：本文提出以改善动力学条件为重点的造渣最佳化工艺模型,其总体设计是根据铁水的Si、P含量及设定的炉渣碱度、(TFe)和[P]_F含量,依次估算出渣量(W_(SL))、目标磷分配比(L_P)、磷平衡分配比(L_(P-E))和目标去磷偏离平衡值(n_P);当n_P≈1.1时,则设定的W_(SL)、CaO/SiO_2、(TFe)和T等值达到最佳化;然后根据n_P控制模型采取达到n_(P≈1.1的措施。A slagmaking model emphasized by improving dynamic conditions is suggested. This model may cstimatc slag weight (W_(SL)), objective ratio of P distribution (L_p), cquilibrium ratio of P distribution (L_(P-E)) and objective deviaticn from the equilibrium (n_p) on the basis of [Si] and [P]contents in Liquid iron, aimed slag basicity, (TFe) and [P]_F. The W_(SL), CaO/SiO_2, (TFe) and Tare optimized at n_p≌1.1. The measures then can bc adopted to achieve n_p≌1.1 according to the n_p, model.
