ABSTRACT:
This invention is concerned with an improved apparatus system and method for removing liquid coolant from the side marginal edges of a continuously moving metal strip or sheet after it exits from a rolling mill and subsequent to the prior diversion and collection by a suitable device of the liquid rolling mill coolant that may otherwise contact and deleteriously rewet the top and bottom surfaces of the moving strip as it exits from the mill. The invention in its preferred embodiment involves use of a pair of improved combination strip edge wiping or contacting roller and vacuum creating units that are located adjacent the path of travel and each of the opposing side marginal edges of the moving strip. The roller in each unit serves not only to track and properly locate the vacuum creating components relative to a marginal side edge of the strip and thus maintain substantially continuous contact therebetween but at the same time advantageously functions to remove and divert coolant away from the strip edges in and of itself. In effect the combination strip edge contacting rollers and associated vacuum creating elements of the units act as secondary or supplemental liquid coolant diversion and removal devices that insure the final capture and removal of substantially all liquid coolant from all portions of the strip prior to coiling whereby the strip can be said to be substantially coolant free.
