摘要： PURPOSE:To take up a high temperature steel sheet supplied at a low speed smoothly and continuously into a prescribed size coil by equipping belt wrappers furnished with heat resistance metallic belts respectively on plural take-up machines provided on a line of a steel sheet production equipment by a continuous casting device. CONSTITUTION:A thin plate ingot 62 cooled, e.g. nearly at 600 C is advanced by tagential rolls 57 and pinch rolls 56 on carrier rollers 55. A dummy sheet 60 and an unstationary part of sheet thickness at the starting time of casting are cut off by flying shears and transferred to a take-up equipment 30. The front end part is fed by the deflector pinch rolls 18 with a gate change-over mechanism to a heat resistance mandrel 1 of the take-up machine 10, coiled by a belt wrapper 16 on the heat resistance mandrel 1 and when a required number of layers is taken up, a belt wrapper 16 is moved to right and left and taken up on a thin plate coil 63. When the coil reaches a required size, the advancing thin sheet ingot 62 is cut off, fed to the take-up machine 10 and taken up.
