The Viscosity of Refining Slag on Iron and Steel Refining. Viscosity is an important performance index for refining slag to be controlled. The viscosity of refining slag has an important influence on the smooth smelting process, heat and mass transfer, and thus on the reaction rate of deoxidation and desulfurization, the loss of steel in molten slag, lining life and so on. The viscosity of the solute depends mainly on the composition and temperature of the slag. The viscosity of LF furnace slag is generally 0.25-0.5Pa. S.
In actual production, the viscosity of refined slag will change with the change of temperature. The slag of slag transfer furnace is added 41%. In addition, the content of various metal components is different in different refined slag systems, especially the content of alumina has a great influence on the viscosity of refined slag. Alumina is amphoteric oxide, in the alkaline slag, when the content of alumina is less than 10%, the impact on the viscosity is small, when the content of alumina is greater than 10%, with the increase of the content of alumina, refining slag viscosity also increases.
