A rolling mill, particularly one capable of forming a hot, continuously cast metallic strand into a strip with a large bite and with one pass per mill stand, uses only two small diameter rolls per stand, each mounted for rotation in a pair of chock blocks and each having a comparatively narrow, enlarged diameter working portion. The outer surface of the working portion is profiled to maintain the product centered on the rolls and to accommodate for thermal expansion. The roll also includes an internal, longitudinally extending passage that receives a flow of coolant to control its temperature. |
