  • Treatment Of Steel In Its Molten State (AREA)

Abstract

PURPOSE: To treat large quantity of molten efficiently, by opening the lower end of a treating tank for molten metal without forming bottom wall, by connecting the upper end edge of a immersing cylinder to the edge of the opening removably thereby forming ascending and descending flow passages.
CONSTITUTION: A treating tank for molten metal, where molten metal is treated by letting the molten metal flow in, or flow out of, the tank so as to circulate through the tank, has no bottom at the treating portion for molten metal, and connects with an immersing cylinder 4 removably at the flange F1 of its lower opening and the flange F2 of the immersing cylinder 4. In one side wall of a partitioning wall 6 made in the cylinder is made a gas spouting hole 7, to the top end which is fitted a spouting hole 8 made of porous brick. Similar gas spouting hole is made in the inner wall of the cylinder facing the partitioning wall 6. Hereby an ascending flow passage A and a descending flow passage B are formed. The ratio of the sum S1+S2 of total cross-sectional areas of both flow passages S1, S2 to the area S of lower opening is set ≥0.3. Desired treatment of molten metal is performed by circulating the molten metal through the treating tank for molten metal having said constitution by addition with desulfurizing agent or dephosphorizing agent.
