Filed: 1993-07-15
Abstract: PURPOSE:To prevent the sticking of metal developed at a meniscus position by forming the wide main wall surfaces of a nozzle at the upper position from the immersion part of the pouring nozzle to a thin thickness. CONSTITUTION:The cross sectional shape of an electric conductive heat generating nozzle 11 is formed into a thin box type composed of the wide main walls 16 and the narrow side walls 17. The whole electric conductive heat generating nozzle 11 is made of the electric conductive aluminum graphite. Further, both wide main walls 60 are made to be thin. The electric supplying lead parts 35, 39 along the narrow side walls 17 are beforehand connected with ceramic bolts 48 having the same material as the electric supplying lead at the lower part of the nozzle immersed into the molten steel. Further, the electric supplying lead part 39 and the nozzle surface immersed into the molten steel are stuck to an insulating material 49. Joule heat is generated and the temp. is raised at the meniscus position because the current detours to the nozzle immersion part by conduction. At this time, as the electric current is supplied to the meniscus position of molten metal and the nozzle immersion part is insulated so as to prevent the leakage of electric current into the molten metal, the leakage of the electric current to the molten steel is prevented.
