Abstract (en)

[origin: US5402993A] The invention is directed to an immersion casting pipe for feeding molten steel from a casting vessel into a mold having wide side walls and narrow side walls for the production of flat products. The immersion casting pipe has a pipe piece which adjoins the casting vessel and expands in cross section in the direction of the narrow side walls of the mold. The pipe piece is provided with a central base member at the lower end which allows for outlet openings for the melt. For the purpose of developing an immersion outlet which allows higher slab withdrawal speed of up to 6 m/min with slabs measuring 50 to 100 mm in thickness and 600 mm to 2000 mm in width, the inner wall of the portion of the immersion casting pipe which widens in cross section forms flow channels in conjunction with the opposite wall parts of the base member. The axes of the flow channels enclose an angle alpha between 10 DEG and 22 DEG , where the smaller angle corresponds to a distance of approximately 600 mm between the narrow side walls of the mold and the larger angle corresponds to a distance of 2000 mm or more between the narrow side walls of the mold. The distance between the wide side walls of the mold is 50 to 100 mm.
