摘　　要：针对转炉冶炼低温低硅铁水终点磷含量偏高的现象,从冶炼前期成渣条件、氧枪吹炼枪位等几方面因素对脱磷的影响进行了分析。通过改善化渣条件、采取留渣操作和低温操作等相应措施,有效降低了终点钢水中的磷含量。Aiming at the phenomenon that high phosphorus content exist at the endpoint of smehing low silicon hot metal at low temperature in converter, we analysis a few factors which influence dephosphorization, such as the condition of early stage of the smelting slag, lance position of oxygen lance blowing gun. By improving the condition of slag and taking slag operation and low temperature operation, we reduced phosphorus content in the end of molten steel effectively.
