Slag wool was prepared in laboratory by four-roller centrifugation method using blast furnace slag with 1.25 of acidity coefficient as raw material.The microstructure,diameter,shot content and moisture,mineragraphy and crystallization temperature of the obtained slag wool were analyzed.The results show that the slag wool is solid cylindrical fiber with smooth surface,and its diameter,shot content and moisture is respectively 4.9 μm,3.76% and 0.73%,satisfying the international standard overall.Furthermore,the slag wool has a higher vitrification degree with about 882℃ of crystallization temperature and almost no crystallization except for a very small amount of calcium aluminum melilite(Ca[Al(AlSi)O7]) and calcium magnesium melilite(Ca2MgSi2O7).
