<p>PURPOSE:To secure stable strip passing property and shape quality by previously finding the difference of mill rigidity between the work side and drive side of a rolling roll and presetting the leveling of the roll gap of the mill. CONSTITUTION:A difference is made in mill rigidity between the work side and the drive side of the rolling roll, for example, when the mill rigidity on the work side is larger than that on the drive side, the roll gaps on both side are adjusted to the same SO as shown in (A) before the material is bitten in, the roll gap SWS on the work side becomes smaller than the roll gap SDS on the drive side as shown in (B) after the material is bitten in. Consequently, before the material is bitten in, the initial roll gap SOWS on the work side is adjusted previously to be larger as shown in (C) than an initial roll gap SODS on the drive side before the material is bitten. When the material is bitten in under this state, the roll gaps on both sides become equal as shown in (D).</p> |
