摘要： PURPOSE:To shorten the working time for rearranging a rolling stand, and to automate this rearranging work for the rolling stand, by putting a prepared stand on one side of a turntable approaching to a foundation of the mill, by transferring a used stand onto another side of the turntable, and by 180 deg. turning the turntable. CONSTITUTION:A new stand is prepared by insetting a new rolling roll and by connecting a cable bearer 38; this new stand is put on the rails 33, 34 installed on one side of a turntable 3. A used stand 1 is released from the fixed state and is moved to the right along the rails 22, 23, by a stand driver 13; hereby, the used stadn 1 is transferred from the foundation 2 onto the rails 31, 32 installed on the table 3 and is stopped therein. The table 3 is then 180 deg. turned in the arrowed direction by a table driver 4, and is stopped when the rails 33, 34 are aligned with the rails 22, 23 installed upon the foundation 2. The new stand is then moved to the left, is transferred onto the rails 22, 23, and is stopped and fixed therein.

摘要： PURPOSE:To quench a pipe uniformly and assurely by a small-type device, by a method wherein cooling water is forcibly passed on the inside and outside surfaces of a pipe while moving the pipe in the longitudinal direction to cool the pipe uniformly. CONSTITUTION:The pipe 4 to be quenched is fed into an outer cylinder 11 via a door 12 by a roller table 15, and the door 12 is closed. The pipe 4 is moved forward while cooling the outside surface of the pipe 4 by jetting cooling water from each nozzle 13 provided for the outer cylinder 11. In addition, cooling water is jetted also from a movable nozzle 19 fitted into the leading end part of the pipe 4, thereby forcibly cooling the inside surface of the pipe 4. By rotating a sprocket 16, the nozzle 19 is moved leftward at the same speed as the conveying speed for the pipe 4 while jetting the cooling water from the nozzle 19. When the nozzle 19 reaches the position of a sprocket 17, it is turned along the sprocket 17 so that it is disengaged from the pipe 4, while the latter 4 is fed by the roller table 15 and is taken out to the exterior of the outer cylinder 11. Then, the nozzle 19 is returned to the initial position and is stopped in situ.

摘要： PURPOSE: To make the movement of a mandrel bar unnecessary, and to shorten the working time for handling the mandrel bar, by grasping neighborhood of both ends of a stationary mandrel bar respectively with a grip possible to optionally close and open, and by threading a shell in the axial direction while adjusting the aperture of this grip.
CONSTITUTION: An end of a mandrel bar 4, laid longitudinally in front of a rolling mill 1, is grasped and upheld by a grip 7a of a thrust block 6a arranged in front of the rolling mill 1. Whereas, a grip 7b of a thrust block 6b, arranged on the side of the rear end of the mandrel bar 4, is opened; a shell 3 is then axially taken into a prescribed position between these two blocks 6a, 6b by carrier rollers 8 so as to surround the bar 4 with the shell 3. The grip 7b is then closed to grasp the bar 4, and the grip 7a is opened; under this condition, the shell 3 is fed into the rolling mill 1, and the outer surface of the shell 3 is rolled by the rolling rolls according to a method similar to the conventional method, and a seamless steel pipe is manufactured.

摘要： PURPOSE:To improve control accuracy at the initial stage and to remove the dispersion of wall thickness by storing a converged bar diameter correcting parameter and using the bar diameter correcting parameter as an initial value when a mandrel is used at the next time. CONSTITUTION:In a rolling process 30, a mandrel mill 10 is controlled according to a fixed rolling schedule, the dispersion of a bar diameter is obtained based on the drawn result of the mandrel mill 10, a roll interval is corrected corresponding to the dispersion and this correction parameter is obtained by a mandrel bar 15. The drawing is completed and when a mandrel bar 15 different in diameter is used for drawing a tube stock 1 different in size, a bar diameter parameter of each mandrel bar 15 which has been used are stored in a bar control computer 31. When the mandrel bar 15 is used thereafter, a bar diameter correction parameter is read from the bar control computer.
