摘要：A system for controlling front and tail end gauge of a continuous hot rolled

product in a rolling mill includes first and second individually driven roll stands (58, 60)

arranged successively along a pass line (22) in advance of a group of roll stands. A

controller (28) adjusts the operating speed relationship between the first and second

individually driven roll stands to achieve an increased level of tension in the front and tail

end segments of the product passing between the first and second individually driven

roll stands. The increased level of tension results in the decrease in product cross

sectional area sufficient to compensate for the lack of cross sectional area reduction

resulting from the absence of interstand tension experienced by said front and tail end

segments while being rolled in the group of roll stands. To control the gauge of the

front end of the continuous hot rolled product, the controller commands a decrease in

the speed of the first roll stand as front end approaches the second individually driven

roll stand, which is located adjacent to and downstream of the first individually driven roll

stand. The reduction of the speed of the first roll stand below a nominal rolling speed

establishes the increased level of tension of the product between the first and second

roll stands when the front end enters the second roll stand. When the front end has

passed the first roll stand, the controller commands the speed of the first roll stand to

return to the nominal roll speed to roll the segment of the product between the front

and tail ends. To control the gauge of the tall end of the product, the controller

commands a decrease in the speed of the first roll stand as the tail end approaches the

second individually driven roll stand.
