Abstract
PURPOSE: To locally separate the backup roll and the work roll in a distance equivalent to thickness of the liquid film, and to facilitate the control of the bending action for the work roll, by locally spouting the liquid to the contact part between the backup roll and the work roll.
CONSTITUTION: Before feeding the material to the hot strip finishing mill 8, the liquid feed rate to be set in predetermined by the process computer 9 for the finishing mill from the aim crown size of the rolled material 1. Then the bender controller 10 spouts the specified rate of liquid from the nozzle 4 through the flow control valve 5 against the contact part in the longitudinal middle of the work rolls 2 and the backup rolls 3 installed in two stages on the downstream side of the finishing mill 8. Next, after feeding the material to the mill 8, the rolling load and the mill speed are measured respectively by the load cell 11 for the roll 3 and the speed meter 12 for the roll 2, and the liquid flow rate is controlled so as to form the liquid film in a constant thickness. Besides, the liquid flow rate is also controlled by the measuring signal produced from the shape detector 13 installed on the run- out side of the mill 8. As a result, the rolling work for the rolled material 1 is controlled to obtain the aim crown and shape.
