摘要： PURPOSE:To provide the titled quick cooler which cools quickly and continuously a rolling material with a high heat transfer rate by making movable upward and downward an upper header part and permitting the change over to an optimum cooling method, i.e., slit laminar method of water jet method. CONSTITUTION:A driving motor 7 is started to move upward the upper header part 6 slightly before the front end of the rolling material starts passing through the cooler. The position is controlled to set exactly the upper header part to the standby position for the upward movement by the detection signal of a PLG15 disposed at the end of a motor shaft in this stage. The motor 7 is run backward and the header part 6 is moved downward by the above- mentioned mechanism so as to be set exactly at the position for forming cooling water when a coiler begins to coil the front end of the rolling material 1 upon completion of the passage of the front end of the rolling material. The header part 6 is again moved upward and is set in the standby position in the stage of passing through of the rear end of the rolling material. The repetition of a series of upward and downward movement cycles of the header part 6 is thus made possible by the above-mentioned lifting mechanism. A cooling method using high-velocity water jet flow is adopted for cooling of the rolling material 1 in the position for forming the cooling water and a cooling method using a slit laminar flow from a slit nozzle is adopted in the standby position for the upward movement.

摘要： PURPOSE: To perform the high speed continuous coiling of a rolling stock by providing an upper roll to offset against a lower roll and by equipping the main pinch roll movable vertically.
CONSTITUTION: The pinch rolls 9, 10 of the downstream side in the progressing direction of a rolling stock, namely the side approaching deflectors 15, 16 are main pinch rolls and the pinch rolls 17, 18 of the upstream side are sub-pinch rolls. The upper roll of the main pinch rolls 9, 10 is movable vertically by the hydraulic cylinders 29, 30 to be controlled via the electricity-hydraulic servo mechanism. The main pinch rolls 9, 10 perform the nose bend of the tip at the advancing time of the rolling stock with the state of the upper roll being descended and the upper roll is offset in the progressing direction against the lower roll so as to make the rolling stock progress downward.

摘要： PURPOSE:To prevent the center of a roll from being shifted to the direction of a roll axis by providing projecting parts to the outside end of a roll chock, and connecting them eccentrically and freely rotatably to the roll. CONSTITUTION:When a roll 6 is slanted, the roll 6 and a roll chock 3a are moved in circular-arcuate motion in the same direction, and sliders 21a, 21b are moved straightly while following crank plates 19. Eccentric rolls 22a, 22c inserted into the sliders 21a, 21b are moved also in the same direction. By said movements, eccentric axes of the rolls 22a, 22b are rotated eccentrically with radii corresponding to the extent of eccentricity and are moved on the circular circumference of a radius with a roll cross point as a center while following projecting parts 20a, 20b of the chock 3a. Accordingly the roll 6 and the chock 3a are not subjected to a force in the direction of the roll axis, then the slide abrasion at the bearing surfaces between upper and lower chocks and roll bending cylinders are prevented and the power for driving respective cross rolls is reduced.

摘要： PURPOSE:To easily set the parallel position of two work rolls, by utilizing that a moving speed in the axial direction of roll and a thrusting force are proportional to a crossing angle formed by two roll axes, in a roll-cross type rolling mill. CONSTITUTION:Mutually crossing rolls of a roll-cross type mill are rotated, and a thrusting force or a roll chock speed is detected between a roll chock at one side and a thrust clamp; the central position between two zero points of thrusting force obtained by crossing two rolls to one direction or to the reverse direction in the contacting surface, between the two rolls, by a roll-crossing device, or the central position between two zero points of roll-chock speed is made as the parallel position of heads of the roll-crossing device. In ordinary rolling, the heads of the roll-crossing device are set as the parallel position according to the position where respective rolls stabilize, or are set by shifting the head at one side from the parallel position by a gap portion between the head and the roll chock.
