Abstract
PURPOSE:To effectively execute adjustment of components in molten pig iron and molten slag and to improve the yield of component adjusting material by pouring the fine particle component adjusting material at the dropping position in a molten pig iron trough or a molten slag trough to the molten pig iron flow or the molten slag flow at the specific ratio. CONSTITUTION:To the molten pig iron flow 3 or the molten slag flow or mixing flow of the molten pig iron and the molten slag flow discharged from molten pig iron tapping hole 2 or molten slag tapping hole in the blast furnace 1, the fine grain component adjusting material is injected at the dropping position in the molten pig iron trough 4 or the molten slag trough. This component adjusting material having <=5mm grain size is used at max. 50kg/T.P. ratio. The above component adjusting material is stirred by dropping energy of the pouring and the molten pig iron flow, etc., and free degree of the additional quantity can be improved. Further, the poured component adjusting material gives the effect at high yield without any spattering. By this method, the molten pig iron flow 9 effectively executing the desulfurization, etc., is recovered in a runner 12 through a skimmer 11 or the molten slag flow 8 improving basicity, etc., is recovered from the slag-off hole 10.
