<p>PURPOSE:To enable accurate measurement of plate thickness at outlet side of each intermediate stand by establishing the relation of mass flow balance at all times correcting amount of unbalance of mass flow between stands. CONSTITUTION:When a sampling start signal is given to a sampling control device 17, signals are sent to sampling devices. The number of rotation N1 of rolls of F1 is sampled from a tachometer 12, rolling load P1 from a load cell 19 and roll position S1 from a roll position detector 20 and sent to an arithmetic device 18. The arithmetic device 18 calculates transfer time tau12, sends it to the control device 17, gives sampling command to sampling devices, samples angle and angular velocity of looper between F1-F2 and sends to the arithmetic device 18. The device 18 calculates transfer time tau23 between F2-F3 and commands data sampling at No.3 stand. Similarly, sampling is made up to No.6 stand. After sampling necessary data, the device 18 calculates plate thickness at outlet side of each stand using the formula of forward slip.</p> |
