摘要： At least one lance is disposed substantially vertically so that the lower end of molten iron of a shaft furnace is isolated from the surface of molten iron flowing through a melted iron trough at a predetermined interval above the trough, and particularly component adjustor for adjusting the components of the molten iron is blown from the lance via carrier gas into the molten iron so as to satisfy the following two relational formulae:
where in the formulae (1) and (2) H: depth of molten iron in the trough (mm); Hp: depth of blowing particular component adjustor into the trough; M: flow rate of particular component adjustor (kg)min.); G: flow rate of carrier gas (Nm 3 /min.);r: average particle diameter of particular component adjustor (mm); D: inner diameter of lance (mm); and H L : distance between the surface of the molten iron in the trough and the lower end of the lance (mm).
