Abstract: In an endless rolling line, a speed of a material to be rolled changes with a flying thickness change. A temperature control device executes predictive calculation of a speed change amount of the material to be rolled associated with the flying thickness change and updates a speed pattern. The temperature control device executes feedforward control of an amount of a coolant to cool the material to be rolled based on a latest speed pattern and a measured temperature value of the material to be rolled in an entry side of the heat exchanger. In parallel with the feedforward control, the temperature control device executes feedback control of coolant volume based on an error between the measured temperature value of the material to be rolled in the delivery side of the heat exchanger and a target value.

Abstract: Respective gaps between a pair of vertical outer surfaces parallel to a pressing direction of a punch and inner surfaces of a cavity portion of a die facing the same, at positions at both ends in a longitudinal direction of the cross-section of the punch, are set smaller than respective gaps between outer surfaces parallel to the pressing direction of the punch and inner surfaces of the cavity portion of the die facing the same, at positions at both ends in a width direction of the cross-section. Burring height formed by pressing a punch for burring toward the cavity portion to insert the punch into the same is generally proportional to these gap values, and therefore the burring height at ends in the major axis direction becomes lower than that in the minor axis direction.
