Abstract
An improved heat extracting chill block roll and method for use in the continuous casting of ribbon-like metal sheet directly from the melt by means of rapid solidification techniques. The resulting product is considerably thicker and more uniform than previously possible by such techniques. A textured chill surface is formed on the roll by multi-sided protrusions having intermediate valleys between the protrusions. This provides a plurality of discontinuous surfaces on the sides of the protrusions. The preferred surface texture is that formed by a conventional knurling tool.
