Abstract

PURPOSE: To increase the product dimensional precision, by decreasing the tension against i+1 stand before the rolling material passes through; stand to allow it to pass through i stand in zero or small tension state, and lessening abrupt tension fluctuations.
CONSTITUTION: The action of tension between i and i+1 stand is indicated by a, and the fluctuation of sheet gauge at the exit side of i+1 by b. The tension between the i and i+1 stands from the point t0 before the material passes through the stand i is decreased to smaller values qradually. At the point t1 where the material pass through the i stand, the tension between the i and i+1 stands is reduced nearly to zero. As a result, the fluctuation of the exit side sheet gauge in the i+1 stand is lessened as indicated by solid line b. In the duration from t0 to t1, with respect to the mild action of the tension between the i and i+1 stands at T01, the automatic gauge control (AGC) compensates almost perfectly, and the exit side sheet gauge in the i+1 stand is controlled as shown in dotted line b. That is, by properly determining the time T01, the fluctuation of the exit side sheet gauges may be lessened, so that abrupt change in rolling state may be avoided.
