摘　　要：针对唐钢二炼钢50t复吹转炉溅渣护炉工艺进行水力学模型实验。通过测定炉衬不同位置处的溅渣量及均匀性,分别对枪型、顶吹流量、留渣量和熔渣黏度对溅渣量的影响规律进行研究。结果表明：与四孔氧枪相比,四孔变角氧枪溅渣能力相对较弱,但不影响溅渣效果;四孔变角氧枪枪位控制在90~110 mm（实际枪位1~1.15 m）,顶吹流量控制在54 Nm3/h（实际吹顶吹流量14000 Nm3/h）,底吹流量控制在1.72 Nm3/h（实际流量为320 Nm3/h）,对炉衬各处的溅渣量能够满足要求。Hydaulic model experiment on slag splashing protection technology according to 50t BOF in Tangsteel has been carried out.The influence of different oxygen lance nozzles,top blowing flux,slag remains and slag viscosity on splashing amount of slag has been investigated through orthogonal design by cold model.It was concluded that the slag splashing ability of variable angle four-hole oxygen lance was lower than that of four-hole oxygen.There was no significant effect on the slag splashing.In order to improve the slag amount of splashing,the lance level of variable angle four-hole oxygen lance nozzles should be controlled from 90mm to 110mm（the actual lance level being from 1.0m to 1.15m）.The top and the bottom blowing flux should be controlled at 54 Nm3/h（the actual top blowing flux being 14000Nm3/h）,and 1.72Nm3/h（the actual bottom blowing flux is 320Nm3/h）,respectively.
