Abstract of the Disclosure A method for continuously casting strip material onto a casting surface moving past a nozzle in a molten metal holding tundish is disclosed comprising the steps of pouring molten metal into the tundish at a rate sufficient to establish a metallostatic head pressure of at least one- quarter pound per square inch at the nozzle within one second after pouring is initiated, and pouring additional molten metal into the tundish at a rate sufficient to maintain a substantially constant operating pressure at the nozzle throughout the casting operation. A tundish for holding molten metal to the cast into strip material onto a casting surface, moving past a nozzle in the tundish, is also disclosed comprising a front wall having an inside surface, a rear wall having an inside surface and sidewalls enclosing a molten metal holding area defined between the inside surfaces of the front and rear walls. The inside surface of the front wall converges with the inside surface of the rear wall at least at a location near the nozzle.
