摘要： PURPOSE:To improve the quality of an expanded pipe by a simple mechanism and to prevent the spattering and overconsumption of a lubricant, by spraying the lubricant on a rolling part from a plug during plug-mill rolling, and blowing a high-pressure gas from the front end of a plug bar to the return direction during return stroke. CONSTITUTION:In plug mill rolling, a lubricant 14 is supplied 20 to the flow passage 19 of high-pressure gas 15 to supply the lubricant 14 from nozzles 39 to a rolling part through supplying pipe lines 17, 38 in order to lubricate the rolling part. In return stroke, a plug 3, 4, 35 is separated from a taper contact-surface 34, and the spraying is stopped by a spool 45 advanced by a spring 50, and only the high-pressure gas 15 is sent to a front-tip fittings 6 of plug by changing valves 20, 30 by the signal control 32 of a load cell 31 of roll 5b. Accordingly, the high pressure gas 15 is blown to the return direction from the flow passage and a nozzle 43, to descale and clean the inner surface of an expanded pipe 4, thereby improving the quality of the inner surface of pipe 4 and preventing the spattering and overconsumption of lubricant 14.

摘要： PURPOSE:To reduce a preparing period and to improve the operating efficiency of a plug mill by controlling the timings of the acceleration and deceleration of each rolling roll and return roll and of the release of each roll, and the kickout speed of the return rolls, to optimum values. CONSTITUTION:A pair of rolling rolls 12, 14 and a pair of return rolls 16, 18 are arranged at a prescribed distance and are driven by a signal of a control part 34. A rolling material to be rolled such as a steel pipe 26, etc., inserted to the rolls 12, 14 is rolled at a biting speed larger than a return speed of the rolls 16, 18. Rolling is decelerated immediately before finishing the rolling to release the given rolling rolls from a fixed biting position at the time of finishing the rolling. The return rolls 16, 18 are accelerated to return the material 26 to the inserting side and decelerated immediately after kicking it out. When the material 26 is carried to a feeding position, draft setting is performed and the rolls 12, 14 and the rolls 16, 18 are accelerated to the prescribed speed till the setting is completed.

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.
