ABSTRACT:
A method for producing wide strips of copper is performed by pouring a molten liquid into a revolving wide strip mold via a distribution container and a pour nozzle. A surface of the molten metal in the distribution container is maintained at a constant level above the place where the pour nozzle is fixed in the distribution container in the range of 75 mm to 90 mm with respect to the level of the bath surface of the mold. The molten metal is guided by an ascending channel from the distribution container to the pour nozzle and is distributed within the pour nozzle symmetrically over a width corresponding to the width of the strip. Within the pour nozzle, the molten metal is guided through first and second flow restrictors and is separated into numerous small individual flows in a vertical direction over the entire strip width of the mold.
