Abstract：A hydraulic model experiment on BF slag retention was made for simulation of the slag tapping in iron-making. Through analyzing affecting factors, the main results were as follow:high oil viscosity and porosity could aggravate oil retention and the floating height showed the opposite situation. So conclusions were drawn, with decrease of slag viscosity and increases of thermal strength of coke and the number of tap hole, the slag retention can be decreased;high floating height of fixed bed material is in favor of tapping slag completely.
