Abstract

PURPOSE: To utilize the fluidizing energy of molten metal so as to accelerate the reaction and to refine the molten metal efficiently, by addn. of reacting agent to the molten metal while the molten metal being poured into a reaction cylinder which is floated on the molten metal contained in a reaction vessel.
CONSTITUTION: After completion of blowing of a converter 11, molten metal 1 is poured into a reaction cylinder 16 which is set in a ladle 14. With progress of pouring of the molten metal 1, the reaction cylinder begins to surface. At the same time, a flux, i.e., a reacting agent, is added into the reaction cylinder 16. The flux is slagged in the reaction cylinder 16 to form slag 5. The slag 5 and the molten steel is stirred as shown by arrows A due to the fluidizing energy of the tapping flow 2. The stirring is achieved effectively in the limited space in the reaction cylinder 16, so that the reaction proceeds quickly. Clean molten steel 3 flows out through the bottom opening of the reaction cylinder 16 into the ladle 14 as shown by arrows B. Because the molten steel is never in contact with slag 5 contained in the cylinder 16, no rephosphorization is caused.
