Abstract
PURPOSE:To refine the temperature control for the rolled material, by measuring the water pressure and the flow rate of water of the cooling water supply, and by computing the effect of the water spray, nd by correcting the required flow rate of cooling water depending on the result of above computation. CONSTITUTION:when the rolled material 11 arrives at the exit side of the rolling mill, the rolling speed (13), the temperature (16), the thickness (14) and the breadth (15) are actually measured, and the deviations of these data from the data of the rolling schedule are operated. Depending on the result, the correction of the flow rate of cooling water and the spraying pattern are carried out for every arbitrary increment length of the rolled material. When the rolled material 11 arrives at the detector 19 for the temperature of rolled material on the entry side of the coiler, the temperature of rolled material is measured, and the deviation of this measured temperature from the aim coiling temperature is obtained; depending on this result, the correction of the flow rate of cooling water and the spraying apattern is carried out for every arbitrary increment length of the rolled material. The coiling speed detector 23 is used for detecting the speed of the rolled material whose tail end passed through the rolling mill.
