| Abstract: | The ladle slag control process in clean steel production is introduced and various properties of the modified refining slag investigated.Results show that the FeO and MnO quality fraction in the slag could be lowered to less than 3 % and low melting point and low viscosity ensured sound fluidity.The dissolution rate of Al2O3 into slag is relatively high,which resulted in high level of slab cleanliness.Strong desulphurization capability is obtained owing to the high optic basicity and desulfurization capabil... |
