Abstract
PURPOSE: To obtain sufficient sheet gauge precision, without disposing expensive high response screw-down devices in all stands, by disposing a screw-down device of high response speed in the downstream part of stand group.
CONSTITUTION: In the case of automatic gauge control (AGC) by disposing high response screw-down devices in all stands, the final sheet gauge precision shows ΔHn1 as shown in curve 1. On the other hand, in the case of AGC without disposing high response screw-down devices in all stands, the final sheet gauge precision shown an inferior value ΔHn2 as compared with curve 1. However, when a high response screw-down device is disposed only in the final stand, the final sheet gauge precision is closer to the sheet gauge deviation in curve 1, indicating ΔHn3 as shown in curve 3. Further, when high response screw-down devices are disposed in the final two stands, the final sheet gauge precision is identical with that shown in curve 1. As a result, since rolling can be performed under low reduction in the downstream side stands by disposing stands for rolling high reduction in the upstream stands, the response of the screw-down device may be increased.
