PURPOSE:To eliminate the development of nozzle clogging and paddle brake and to smoothly obtain a metal strip by arranging flow changing piece in molten metal basin part in the discharging nozzle and enabling prevention of sticking of molten metal spray to wall face of the outlet slit, etc. CONSTITUTION:In this molten quenched metal strip producing apparatus, the discharging nozzle 4 for the molten metal combined with a tundish 1 is arranged. An outlet slit 7 at the bottom wall of this nozzle 4 is arranged as facing to a rapidly cooling body 8. Plugging and flowing-out of the molten metal are freely executed with a stopper 2 at the upper opening part of the molten metal basin 9 connecting with the above slit 7. Then, the flow charging piece 6 is set in the molten metal basin 9 and by this, at the initial stage of opening the stopper 2, the spray of the molten metal is not made to jump into the outlet slit 7. |
