Experimental Study on Optimization of Slag Splashing Modifiers with Magnesite Tailings
Abstract:
The pile up of Magnesite Tailings cause serious environment pollution and mineral resources waste. When making the low-carbon steel or the ultra low-carbon steel in middle or small size converters, the slag superheat is always higher due to the higher tapping temperature. In order to reduce the tapping temperature, after blowing is also needed, which wil cause the contents of FeO in final slag get increased, the slag with lower viscosity, and the contens of MgO in final slag cant get saturated. So Slag Splashing should not proceed immediately that we must slag Modifiers. The modifier was synthesized by calcined magnesite and anthracite powder,modifier takes the treatment of slag. The experimental result show that the slag has a higher melting point and a suitable viscosity to achieve the requirements of slag splashing.
