摘　　要：以调质高炉渣为原料在实验室进行了四辊离心法制备矿渣棉实验。研究高炉渣滴落温度、粘度、离心辊径及转速等工艺参数对矿渣棉成纤效果的影响规律。结果表明,高炉渣滴落温度应控制在1290-1420℃之间,高炉渣粘度在1-3 Pa.s;四辊直径分别为1^#213 mm、2^#295 mm、3^#295 mm和4^#295 mm时,转速控制在1^#2707-3000 r/min、2^#3093-4000 r/min、3^#4350-4500 r/min和4^#5000-5800 r/min,成纤率较高,成纤效果良好。Using conditioning blast furnace slag as raw material to carry out the experiment with the four high centrifugation preparation of slag cotton in the laboratory. The effects of process parameters on slag cotton fiber rule were studied,such as slag dropping temperature,viscosity,centrifugal roll diameter,rotation speed and so on. The result shows that the fiber- forming rate is higher and the effect is better. When the blast furnace slag dropping temperature was controlled in 1 290—1 420℃,the slag viscosity was in 1—3 Pa·s,the four-roller diameters were 1^#213 mm,2^#295 mm,3^#295 mm,3^#295 mm,the rotation speed was controlled in 1^#2707—3000 r/min,2^#3 093—4 000 r/min,3^#4350—4500 r/min,4^#5 000—5800 r/min.
