| Abstract: | 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# 2 707—3 000 r/min, 2# 3 093—4 000 r/min, 3# 4 350—4 500 r/min, 4# 5 000—5 800 r/min. |
