摘　　要：为了分析转炉冶炼过程中的回磷情况,在对回磷的机理分析基础上对各影响因素进行了分析研究。结果表明,在冶炼45号钢时,若使回磷量(质量分数)控制在0.002%以内,转炉出钢温度需控制在(1660±5)℃,其钢包渣厚至少需控制在75 mm以内,终渣w(TFe)需控制在12.1%以内。In order to analyze the situation of dephosphorization in converter smelting process,based on the analysis of the mechanism of dephosphorization,the influencing factors are analyzed and studied.The results show that the tapping temperature of converter should be controlled at(1660±5)℃,the ladle slag thickness should be controlled within 75 mm and the final slag w(TFE)should be controlled within 12.1%if the amount of dephosphorization(mass fraction)is controlled within 0.002%.
