METAL STRIP CONTINUOUS CASTING DEVICE

摘要

PROBLEM TO BE SOLVED: To accurately control thickness of a strip during casting. SOLUTION: A pair of parallel casting rolls 1 are mounted to stub shafts 21 and 22 which extend from the ends of the casting rolls 1 and are rotatably fixed to journal bearings 65 and 66, so as to constitute a metal strip continuous casting device. The casting rolls 1 are cooled with a water flow of an inside water flow passage, into which the water is supplied via a rotary water flow joint 40 mounted to the stub shaft 22 at one end of a roll assembly, and are rotated by an electric motor being a roll driving means 71 mounted to the opposite side end of the rotary water flow joint 40 of the roll assembly. The roll driving means 71 is supported on the stub shaft 21 and balanced with the supporting weight of the rotary water flow joint 40.
