Abstract
PURPOSE: To obtain a steel material of superior surface characteristics without causing rimming action by stirring the molten steel, which is obtained after it is subjected to the top and bottom blowing of blowing a stirring gas from the tuyere in the furnace bottom simultaneously with top blowing of oxygen, vigorously in a nonoxidizing atmosphere, and adding Al during this stirring vigorously, thence subjecting the same to continuous casting.
CONSTITUTION: In converter blowing, the top and bottom blowing of bottom blowing a stirring gas from the furnace bottom together with the top blowing of oxygen and the resultant molten steel is introduced into a ladle 1. A cap 4 provided with a sealant 3 is put on the ladle 1 to tightly seal the ladle. Caseous Ar is blown through a top blowing lance 5 to put the inside of the ladle 1 in a nonoxidizing atmosphere, thence Al is added from a hopper 6. The Al reacts with the oxygen in the molten steel 2, whereby disoxidation is carried out. The molten steel obtained in this way is treated in an ordinary continuous casting process.
