Abstract

PURPOSE: To carry out effective refining in a ladle with high safety by lining each air hole in supporting brick with a heat absorbing tube to solidify molten metal penetrating into the hole and prevent the metal from flowing out of the hole.
CONSTITUTION: Heat absorbing tubes 7 such as stainless steel pipes are inserted into air holes in supporting brick 5. When bubbling is stopped at a state where fusion loss of porous brick 3 reaches the limit of safety use or abnormal fusion loss is caused in brick 3 by some factor, molten metal is apt to flow out of the holes, yet by the cooling action of tubes 7 molten metal penetrating into the holes is immediately solidified and clogs the holes. Accordingly, penetration of molten metal into the holes is restricted to a small amount, and leakage is prevented perfectly to ensure high safety.
