PROBLEM TO BE SOLVED: To provide housing accuracy measurement methods and devices for a cold rolled steel sheet skin pass mill capable of measuring housing accuracy properly by using whole width measurement.SOLUTION: A recess part is provided on one of a pair of housing liners, the one of the pair of housing liners being disposed on an opposite side of a reference surface side where a roll chock is pressed against a mill housing by offset force component. A bottom surface of the recess part serves as a fix surface for housing whole width measurement. Distance from the fix surface to the housing liner surface disposed on the reference surface side is measured for determining a whole width measurement value of the housing. |
