摘要： PURPOSE:To manufacture a seamless steel pipe with an excellent roundness along the longitude, by controlling the reeling process according to a control period settled upon a prescribed one point in the circumference of a steel pipe to be rolled, independently of the finishing diameter of the steel pipe or of the diameter of the rolling roll. CONSTITUTION:A measuring device 4 for measuring the number of rotation of a roll is attached to a rolling roll 1 in order to always measure the number of rotation of the roll 1. A control period computer 5 receives the number of rotation of the roll 1 measured by the device 4 at the beginning of the rolling process for a material 2 to be rolled, the rolling specification for the material 2 to be rolled sent from a rolling specification memory unit 6, and the specification of the roll 1 and the designated controlling times per one turn of the material 2 to be rolled sent from an initial set data memory unit 7; the computer 5 then operates a control period from these inputted data. This control period is taken as the next computing timing of the control periord computer 5. These procedures are repeated successively from the beginning to the end point of the rolling process. Meanwhile, a rolling reduction's set point computer 8 computes the set point of the rolling reduction for every control action of the computer 5, and shifts the roll 1 to a correct position.

摘要： PURPOSE:To prevent the variation in the wall thickness of a pipe, and to improve the yield, by controlling the diameter of the pipe to an aimed size of a rolling pass of a sizing mill, while correcting the expansion of the pipe due to a rolling work of a reeling mill, correspondingly to a thickness deviation caused by a plug mill's rolling work. CONSTITUTION:An arithmetic control unit 21 receives following information; material temperature T measured by a thermometer 20; information about the rolling torque Trq sent from torque meters 16, 16' attached to spindles 22, 22' of rolling rolls 10, 10'; wall thickness tp of a blank pipe measured after a plug mill's rolling pass and before being fed to a reeling mill; and outer diameter DP of the blank pipe. The unit 21 then outputs a reduction control signal DELTAE on the basis of said information to a reduction controller 19 which thereby practices the position control for the rolling rolls 10, 10'. Hereby, the roll gap E of rolling rolls 10, 10' is adjusted correspondingly to a difference (DELTAtA-DELTAto) between an aimed wall thickness reduction DELTAto and the actual reduction DELTAtA in the wall thickness. For DELTAtA-DELTAto>0, the gap E is increased, and for DELTAtA-DELTAto
