Status and development of mineral wool made from molten blast furnace slag

This study describes the characteristics of mineral wool and its applications,and also introduces the traditional process of mineral wool made from molten blast furnace(BF) slag.Compared with high energy consumption of the traditional process,the production of mineral wool by using molten BF slag will be able to take full advantage of the sensible heat of molten slag,and also reduce production costs.However,there are also further issues to resolve such as how to obtain the required amount of molten BF slag and how to make it homogeneous.Based on the physical and chemical properties of the molten BF slag,the investigation into the relationship between temperature and viscosity under different acidity coefficients of the slag and silicon mixture was conducted.Combined with the crystallization and phase diagram of slag wool,its heat resistance,water resistance,durability and corrosion resistance were analyzed.Finally,trends of the technology development are proposed.

Effects of oxygen potential and flux composition on dephosphorization and rephosphorization of molten steel

The dephosphorization experiments of low phosphorus containing steel by CaO-based and BaO-based fluxes were carried out. The effects of the oxygen potential in molten steel and the BaO content in the slag on dephosphorization and rephosphorization of molten steel were analyzed. The results showed that the dephosphorization ratio of more than 50% and the ultra-low phosphorus content of less than 0.005% in steel were obtained by the three kinds of dephosphorization fluxes as the oxygen potential of molten steel higher than 400×10-6. Rephosphorization of molten steel was serious as the oxygen content of molten steel lower than 10×10-6. BaO-based fluxes can improve the dephosphorization effect and reduce the phosphorus pick-up effectively under the condition of weak deoxidization of molten steel (the oxygen potential is about 100×10-6), but can not prevent rephosphorization under the condi- tion of deep deoxidization of molten steel (the oxygen potential less than 10×10-6).
