Abstract

PURPOSE: To promote contacting and mixing of refining flux with molten metal and aggregation and separation of the refining flux from the molten metal by adding the refining flux to the molten metal in a refining vessel, horizontally rotating with rotating magnetic field and bringing the revolving flow into no contact with a buffle plate after bringing the rotating flow into contact with the buffle plate at upper side.
CONSTITUTION: The molten steel 5 is charged into the refining vessel lining refractory 2 in the inside of shell 1. The refractory-made buffle plate 3 is projected toward inside at upper part of the static molten steel 5 surface. The refining flux 6 is added on the molten steel 5. Next, the horizontal rotating force is given to the molten steel 5 with a rotating magnetic field generating device 4 arranged at outer circumference of the vessel. At the time of promoting the contacting the mixing of the refining flux 6 with the molten steel 5, the rotating stir bringing the rotating flow 5a of the molten steel 5 into contact with the buffle plate 3 is forcedly executed. On the other hand, at the time of aggregating and separating the flux 6 containing impurity in the molten steel 5 after refining, the rotating flow 5a is not brought into contact with the buffle plate 3 to aggregate the flux, and then, it is removed by using a slag suction header, etc.
