ABSTRACT:
A continuous casting nozzle has a relatively narrow dispensing slot reinforced against flexing along its length by intermittent supporting structure. The nozzle may be a tubular insert member to be received in a mounting means, such as a support plate and providing the reinforcement. The nozzle may be formed from a hollow tubular member with longitudinally aligned sectors or openings formed in the side wall to provide passage of the molten metal to the dispensing slot. The relatively narrow slot is formed in the side wall opposite the openings. The reinforcement ribs are integrally formed between the openings. The end portions of the nozzle member are plugged to direct the molten metal through the dispensing slot. With the nozzle member inserted into the bore in the mounting plate of the crucible, the nozzle assembly is supported along its entire length. The mounting plate may include reinforcement ribs aligned with the ribs of the nozzle member when fully inserted in the plate.
