<p>PURPOSE:To accurately calculate the outlet side sheet thickness just under the rolling mill without obtaining the variation rate of the foward slip by detecting the line speed with the speed indicator, and tracing the inlet side sheet thickness with trucking. CONSTITUTION:No.1 sheet thickness calculating means 7 calculates the outlet side sheet thickness H2 just under the roll 3 due to the mass-flow constant raw with the output of No.1 line speed detector 5 to detect the inlet side line speed V1 of No.1 rolling stand 2, the output of No.2 line speed detector 9 to detect the inlet side line speed V2 of No.2 rolling stand 3, the output h1x of No.1 sheet thickness trucking means 6 to execute always trucking the output h1 of the sheet thickness detector 4 from the sheet thickness detecting position (a) to the inlet side just under the rolling roll 3. The trucking means 6 inputs the output h1 of the sheet thickness detector 4 to detect the inlet side sheet thickness of the stand 2 and the output V1 of the speed detector 5 to detect the inlet side line speed of No.1 rolling stand, and executes always trucking the output h1 of the sheet thickness detector 4 over the distance Le from the sheet thickness detecting position (a) to the position just under the rolling roll 3.</p> |
