Coiler spindle for winding a band-type product and its use

摘要

A coiler spindle for winding a band-type product such as the material coming from a continuous casting machine which includes a central shaft rotatable about an axis and having a set of adjacent segments surrounding the shaft. Each segment is mounted to slide radially on the shaft and comprises a curved plate having an external face in the shape of a cylindrical sector. The diameter of the spindle can be changed by radial displacement of the segments. Cooling of the segments is provided by the circulation of a heat exchanger fluid along each segment from a fluid box fixed to the central shaft and having at least two separate chambers. The chambers including a supply and an evacuation chamber. Each segment is provided with its own individual cooling down system arranged within the curved plate. Each individual cooling down system includes an inlet orifice connected to the supply chamber and an outlet orifice connected to the evacuation chamber. A ductile connector is used to connect each orifice to the respective chamber.
