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 conve...
A method for forming ribbon-like metal sheet directly from molten metal by rotating the surface of a rotating, heat extracting substrate in contact with molten metal to solidify it upon the surface of the substrate, the method comprising: (a) forming a friction enhancing textured chill surface upon a substrate, the chill surface having multi-sided protrusions with interconnected valleys between the protrusions to provide a plurality of discontinuous surfaces which face obliquely toward the direction of travel of the substrate surface; and (b) rotating th...
