Abstract
PURPOSE: To make a tapered composite roll having an outside shell layer of uniform thickness castable by centrifugally casting an outside shell layer and a core material at different angles of inclination while rotating a mold having a tapered inside surface.
CONSTITUTION: A metal mold 11 of wich the inside surface is formed of a tapared surface 14, and which is provided with sand molds 12, 13 for forming roll necks on both sides is inclined at 20W45° angles to horizontal plane in such a way that the small diameter part of the tapered shape comes downward, and while it is rotated by the rotation of rollers in rotary roller supporting parts 15, molten steel of high abrasion resistance such as high alloy steel or high hardness steel for forming the outside shell layer of the roll is first cast. The outside shell layer 10 of a tapered shape wherein the thicknesses t1 and t2 on both sides are equal is formed, the angle of inclination of the mold 11 is increased to 40W45°, and strong and tough ductile cast iron or the like as a core material is cast, whereby a core material 9 including the roll neck parts is cast into one body, and the composite roll is cast.
