摘要： PURPOSE:To facilitate rearrangement of rollers by providing shaft end fixing devices for rearrangement at the end of upper and lower driving shafts. CONSTITUTION:The fixed cylinder 8 of driven side bearing box 4 of an upper roller is unloaded and restraint of the bearing box 4 is released. A cylinder 27 for fixing the upper housing provided in the lower housing is unloaded, and the upper housing is lowered slightly, and the bottom of the leg 28 of the upper housing is brought into contact with the upper face of a slide rail 29 for rearrangement in the lower housing. The upper housing 1 is moved by an upper housing shift cylinder in the direction of separating from the pass line. Consequently, the circumference of the shaft end of driven side roller becomes a wide space, and roller sleeves 18, 18' and driven side bearing boxes 4, 5 can be attached and detached easily to and from roller shafts 17, 17' by utilizing an overhead traveling crane.

摘要： PURPOSE:To prevent burnt-sticking to guides and to improve a rolling efficiency by introducing separately oval-shaped rolled material divided after a slit rolling mill to its short axis direction and right after that, arranging in line the guides introduced to next pass as separating in long axis direction. CONSTITUTION:After dividing the rolled material 10 by a slit pass (a) with about 10 deg. for inclination theta0 of pass, the rolled materials divided are separated only toward upper and lower directions to a roll 15 by a twist-friction guide 11. Next, rolled materials 10-1, 10-2 is introduced as increasing twist angle theta1 of troughs 12 to separate toward right and left direction for each rolled material. As the rolled material has already >=15 deg. twist angle theta1, it has week rigidity of right and left direction, and then, it is not appeared to any burnt seam, because of its little friction force. Next, the rolled material after passing the trough 12 is transferred to next pass (b) through an inlet guide 13 to the next pass and a roller guide 14 at the end part of the inlet guide 13.

摘要： PURPOSE:To cool uniformly a steel pipe over the entire length thereof and to obtain a hardened steel pipe having a good shape by injecting cooling water on the inside and outside surfaces of the steel pipe and transferring the steel pipe in the longitudinal direction. CONSTITUTION:A steel pipe 9 to be hardened is fed longitudinally by a roll table 17. An inside nozzle pipe 5 provided with inside cooling nozzles 7 and self-aligning guide wheels 10 on the outside circumference is held along the table 7 at the approximate center of a cylindrical header 2 with outside cooling nozzles 3. The pipe 9 is guided by the plug 8 of the pipe 5 so as to be held concentrical with the pipe 5, and is supported by the wheels 10. The supporters 6 open successively just after supporting with the wheels and close successively upon passage of the rear end of the pipe 9 thereby supporting the pipe 5. The pipe 9 is cooled by the cooling water from the nozzles 3, 7 during this time, and when the rear end of the pipe 9 passes the range disposed with the nozzles 7, the supply of the cooling water to the pipe 5 is interrupted. An arm 14 is then rotated and raised to pull up a water suction hose 13, etc. to the position where the advance of the pipe 9 is not interfered with.

摘要： PURPOSE:To easily a attach and detach a bearing by suspending projections provided on both upper ends of a bearing box from an L-shaped supporting member provided on a bearing support frame and bringing the bearing box in direct contact with a main frame by means of a clamping device on the upper part of the bearing support frame. CONSTITUTION:WS bearing box 4 is supported by means of an L-shaped hook 7a fixed on the bottom of a bearing support frame 7 provided so as to enclose an upper beam 6 of a main frame. The upper part of said bearing box is so provided as to come in contact with the upper beam 6 of the main frame and is forcibly clamped upward by means of a clamp 8 installed on the upper part of the bearing support frame 7 to prevent a gap on the face of said contact. When the bearing box is unclamped, since the bearing support device is configured so that a gap A' breaks out between the bearing box 4 and the upper beam 6 of the main frame and the box 4 is axially movable, the bearing device can be easily pulled out.

摘要： PURPOSE:To prevent the seizure of a guide, etc. by arranging a pair of the upper and lower inductive rollers at the outlet port side of a friction guide and moreover by making the rotary shaft center of each inductive roller parallel to the straight line which connects the centroid of the bar to be introduced. CONSTITUTION:The friction guide 4 equipped with a twisting hole part at the inner part in the outlet port side position of a slit roll 8 is arranged and inductive rollers 6-1, 6-2 are respectively arranged at the outlet port side of the guide 4 as well. In this case, the rotary shaft centers of the roller 6-1, 6-2 are arranged in parallel to the straight line X-X which connects the centroid of the bar A, A' to be introduced. With this mechanism, the generation of a slippage and bend between the bar and each roller can be prevented by making the pinch radius of each roller to be same. Consequently the stiffness can be improved with the center support of the rollers 6-1, 6-2 as well as the seize prevention between the bar and guide 4.
