Abstract
PURPOSE:To efficiently remove Si containing in molten iron by mainly blowing collected dust generating on the way of sintering process of fine ore on surface of the molten iron. CONSTITUTION:The molten iron 2 and slag flowing out from an iron tapping hole in a blast furnace are separated by a skimmer and the molten iron 2 is sent to a molten iron receiving ladle through a molten iron trough 1. Then, a water cooled lance 6 is inserted above the molten iron 2 from an opening part 11 of a cover 10 on the molten iron trough 1 and the collected dust 12 generating on the way of the sintering process of the fine ore and fluor-spar 5 separately stored into tanks 7 are charged into a piping 8 and blown on the surface of the molten iron 2 through carrier gas 9. Then, the grain size of the collected dust 12 is desirable to be within the range of 0.01-0.25mm. By this method, the Si is efficiently removed without occurrence of any trouble in the molten iron receiving ladle and using any calcined lime.
