Abstract: The cause and damage to produce splashing in converter steelmaking are analyzed and the effect of foam slag inhibitor ingredient, adding amount and adding method on splashing has been discussed. The production results show that with using the optimum ingredient of inhibitor /% : 10~15C, 35~40CaO, 5~l0MgO, 25~30 volatile-matters + ash, inhibitor size 20 ~ 50 mm, adding amount 2 kg/t and with after using foam slag inhibitor the ingredient of slag is /% : 43.97CaO, 17.95SiO₂ , 6.8MgO and basicity 2.45, the expected aim is achieved to decrease slag splashing amount from original 300 - 600 kg/fumace to 100 ~300 kg/furnace, and the production cost per ton steel decreases by 5 ~ 10 yuan.
