Abstract In order to analyze the fiberization mechanism of melting slag and its influencing factors. The fiberization process of molten BF slag was studied experimentally through centrifugal method. Combining the experimental results， factors influenceing the length and the diameter of blast furnace slag fibers were investigated， and the influence of such parameters as roll diameter， roll speed and outlet slag temperature on the centrifugal spinning process and the obtained fibers were also analyzed. Under the experimental conditions， the optimum tapping temperature was 1450 ℃， the four rollers speed of the four-roller centrifuge were 3 840，4 620，5 220 and 5 820 r/min respectively. The results show that the We number and the Oh number of the molten slag must reach 4.223×106-4.28××106 and 3.81×10－2-4.56×10－2 respectively to produce a fibrosis decomposition. The two parameters reflect the relationship among the factors that affect the fibrosis of the slag and finally the expression of fiber diameter and fiber length in the test condition are determined.
