Abstract: Disclosed are process and apparatus for use in the direct casting of metal strip (14) from molten metal deposited on a moving chill surface (12) from a tundish (10) having a floor (30), opposed upwardly extending sidewalls (32, 34), an end wall (36), an open outlet opposite the end wall with the open outlet extending substantially the full width of the tundish between the sidewalls, and an inlet (44) for providing a flow of molten metal (20) into the tundish from a source of molten metal (42). Flow diverters (56, 58) within the tundish divide the flow of molten metal into a plurality of separate streams and divert one of the streams in the direction of each sidewall and for recombining the diverted streams into a composite stream flowing toward the outlet. Flow diffusers (72, 74, 76) diffuse the molten metal flowing through the tundish to provide molten metal of substantially uniform temperature across the width of the tundish at the outlet.

Abstract translation: 公开了一种用于将金属条（14）从熔融金属直接铸造到金属条（14）上的方法和装置，沉积在具有地板（30）的中间包（10）的移动冷却表面（12）上，相对的向上延伸的侧壁（32,34 ），端壁（36），与端壁相对的开放出口，开放出口基本上延伸在侧壁之间的中间包的整个宽度，以及用于将熔融金属（20）流动到所述侧壁中的入口（44） 中间包来自熔融金属源（42）。 中间包内的分流器（56,58）将熔融金属流分成多个单独的流，并且在每个侧壁的方向上转移一个流，并将转向的流重新组合成朝着出口流动的复合流。 流动扩散器（72,74,76）使流过中间包的熔融金属扩散，以在出口处的中间包的宽度上提供基本均匀温度的熔融金属。
