Abstract

PURPOSE:To enable highly-accurate detection, by estimating coefficients for calculating the fluctuation in a torque arm, from the incoming plate thickness, outgoing plate thickness, rolling force and measured torque arm in real rolling. CONSTITUTION:The fluctuations DELTAHiM, DELTAhiM, DELTAPiM, aiM-aiLin the in coming plate thickness, outgoing plate thickness, rolling force and torque arm at an i-th stand 2 from the time of locking-on before the biting-in of a rolled material 1 into an (i+1)- th stand 3 are used to compute torque arm fluctuation coefficients K1, K2, K3 by a calculator 15. After the rolled material 1 is bitten into the stand 3, the coefficients K1-K3, the fluctuations DELTAHi, DELTAhi, DELTAPi in the incoming plate thickness, outgoing plate thickness and rolling force at the stand 2 from the time of locking-on and the locking-on arm torque arm aiL are used to perform computation by another calculator 50. The torque arm ai and the rolling torque Gi, rolling force Pi and rear tension Ti-1 at the stand 2 are used to determine tension Ti by another calculator 60. Data on real rolling are thus used to perform estimation to attain high accuracy.
