Abstract
PURPOSE:To always obtain a uniform rolled product, by measuring an elapsed time in case when a steel pipe is being carried, and constituting so that a load condition in case of rolling is corrected in accordance with an estimated rolling temperature varied in accordance with said elapsed time, in a titled controller. CONSTITUTION:In a controller of a reeler mill 4 for rolling steel pipes 2, 3 carried from a plug mill roller 1 under the set rolling conditions, a temperature, the outside diameter and length of the steel pipe 2 are measured by a thermometer 6, an outside diameter meter 7 and a length meter 8, respectively, are inputted to a computer 9, respectively, and the rolling conditions of the reeler mill are operated and set, and are sent out to a gorge controller 5. In this case, according to this constitution, a temperature is estimated at every prescribed time period when the steel pipe 3 is carried to the reeler mill from the plug mill, the rolling conditions at each time point are reoperated in accordance with the estimated temperature, and the set value is corrected. In this way, a rolled product whose dimension accuracy is high can be obtained by setting the proper rolling conditions corresponding to a constant temperature.
