Title: Method and device for preventing outflow of slag
Inventor: NAKAYAMA TADASHI
IPC: B22D43/00
Filed: 1984-08-27
Abstract: PURPOSE:To close the supply port of an intermediate vessel in preference to the outflow of slag and to prevent the outflow of the slag by pouring a molten steel into a tundish via the intermediate vessel having a floating closing body which is adjusted in bulk specific density from a ladle. CONSTITUTION:The floating closing body 6 in the intermediate vessel 2 is the closing body having the bulk specific gravity larger than the bulk specific gravity of the slag 7 and smaller than the bulk specific gravity of the molten steel 5 and has the spherical or polyhedral shape smaller than an upper aperture 8 which is a port for accepting the molten steel into the vessel 2 and larger than a lower aperture 9 which is the port for supplying the molten steel to the down stream tundish 3. The molten steel is contained from the ladle 1 through the nozzle 10 into the vessel 2 in the stage of pouring. The body 6 floats on the molten steel in this state and does not hinder the pouring of the molten steel 5 into the tundish 3. The body 6 closes the port 9 in precedence to the outflow of the slag 7 when the molten steel 5 in the ladle 1 is supplied together with the slag 7 to the vessel 2 on progression of casting into a casting mold 4.
