ZERO ADJUSTMENT METHOD FOR CROSS ANGLE OF CROSS ROLL TYPE ROLLING MILL

摘要

PURPOSE:To accurately and efficiently perform the zero adjustment of a cross angle by correcting a position of work rolls based on an absolute position of a work roll chock detected by a couple of position detectors. CONSTITUTION:A measuring hole 23 of a suitable dia. is bored in a cross beam 7a on a reference face 6a side of a housing 5 and a detection end 24 of position detectors 20, 20a is freely insertable to the hole 23 with a shift position of upper and lower work rolls 1 set at a prescribed zero point. After that setting, absolute positions are measured and a cross angle is adjusted to be zero following the procedures for a conventional device. The accurate adjustment is performed by that method.
