Abstract
The present invention is to tension and guide hot strip for coiling in a hot strip mill, the hot strip mill includes a runout table with driven rollers for delivering hot strip from a train of finishing mill stands along a pass line of a runout table to a coiler. The coiler having driven mandrel for coiling strip thereon and pinch rolls having an operative position to direct the leading end of strip from the runout table to the coiler and tension the deflected leading end portion of strip during the formation of initial convolutions of coiled strip on the driven mandrel. Gag roll assembly upstream of the pinch rolls at the runout table for tensioning strip conveyed by the runout table after a trailing strip end emerges from the train of finishing mill stands. An actuator moves the gag roll assembly from an inoperative position remote to the pass line on the runout table into an operative position wherein strip is deflected from the pass line sufficiently to partly wrap about a roll face surface of the gag roll thereby tensioning the strip during coiling. The gag rolls are driven by motors to maintain a synchronous speed relation between the rolls surface of the gag roll and the speed of the strip to avoid scratching or marking of the strip.
