    摘要: THE METHOD AND APPARATUS FOR HOT ROLLING STRIP BETWEEN A FINAL PAIR OF REDUCING ROLLS AND A PENULTIMATE PAIR OF REDUCING ROLLS IN WHICH THE FINAL ROLLS ARE DRIVEN AT A CONSTANT SPEED AND THE PENULTIMATE ROLLS ARE DRIVEN AT A VARIABLE SPEED LESS THAN THE CONSTANT SPEED. THE SPEED OF THE PENULTIMATE ROLLS IS INCREASED WHEN THE STRIP BETWEEN THE PENULTIMATE AND FINAL ROLLS IS IN A SUBSTANTIALLY STRAIGHT PASS AND DECREASED WHEN THE STRIP RISES TO A PREDETERMINED

    DISTANCE ABOVE THE STRAIGHT PASS, THUS MAINTAINING THE STRIP BETWEEN THE ROLLS BETWEEN ZERO TENSION AND A SLIGHT COMPRESSION.
