Abstract
PURPOSE:To prevent development of defect of metal strip by arranging a nozzle for submerging in pouring basin part and also plural opening parts on the side wall of the nozzle. CONSTITUTION:The pouring nozzle 4 is formed as double construction of an inner nozzle 5 and outer nozzle 6. The opening parts 7 are arranged on side face at lower part of the nozzle 5 so as to direct to the longitudinal direction of the pouring basin part 3. Further, the plural nozzle holes 8 are arranged in the side wall at the longitudinal direction of the outer nozzle 6 are arranged and the bottom wall 9 is no hole. At the time of submerging the outer nozzle 6 into the pouring basin part 3 at casting, the molten metal 10 spread to the outer nozzle 6 from the inner nozzle 5 is supplied into the pouring basin part 3 as the stream having component of horizontal direction. Then, the molten metal flow under over-heating condition promotes convection in the pouring basin part 3, and development of thin film on the molten metal surface is prevented and solidified shell 11 at initial stage is remelted. By this method, the development of defects of cavity and surface fault, etc., in the metal strip 12 is prevented.
