<p>PURPOSE: To prevent failure of equipment and quality by detecting the position of roll chock with a position detector for cross point correcting. CONSTITUTION: By vertically moving a pair of working roll and stand-by roll 8 with AGC hydraulic actuator 13, the movement of working roll chock of AGC-thickness control equipment, by which thickness variation of rolled material is made flat, is restrained. By pressing a working roll chock 2 and stand-by roll chock 1 in the rolling outlet side direction with using the actuator for cross point correcting, the clearance generated between a cross head 3 and roll chock 2 is eliminated. Further, the position of roll chock 1 is detected by a position detector 6 for cross point correcting. By this method, plate bending generated at liting hot steel strip and generation of meandering/wedge are prevented.</p> |
