Abstract
PURPOSE: Control device, rolling the weld joined part with a high accuracy, by finding timing passing the strip through the upper flow side rolling mill and the deflection of plate thickness and then, operating the timing passing the weld joined part through each rolling mill and roller gap fitting quantity.
CONSTITUTION: Output signal of the entry side thickness gauge 3 of the upper flow rolling mill 1 is sampled in the sampler 11 and is held on the comparision circuit 12 and then, weld joined part is detected comparing with a fixed plate thickness. The deflection of plate thickness is taken in the operation and set up circuit 14. Travelling speed of the strip S is calculated at the circuit 14 by the roller rotating speed and also, rolling point of time of weld joined part is calculated from the distance between the gauge 3 and the mill 1. Moreover, a suitable gap fitting quantity is computed and is set up according to the deflection of plate thickness. Output signal of the load cell 9 of the former stage rolling mill is sampled by the sampler 11 on and after the next stage rolling mill and the value of each point of time is compared with that of one point of time before by the circuit 12. Then, passing timing of the weld joined part and the deflection of plate thickness, are obtained and the gap is fitted synchronizing with the passing of jointed part.
