<p>A high reduction method and apparatus for continuously hot rolling a product through a plurality of roll passes, wherein the distribution of horizontal forces in at least one roll pass other than the first is such that spontaneous entry is prevented by a maximum momentary opposing force which is greater than the available delivery force of the preceding roll pass. An additional force is exerted on the product in advance of the preceding roll pass. This additional force, when combined with the available delivery force of the preceding roll pass, is of sufficient magnitude to overcome the maximum momentary opposing force of the said one roll pass and thus achieve forced entry therein.</p> |
