摘要： PROBLEM TO BE SOLVED: To enable high efficiency rolling by preventing the vibration of a mill by improving the workability of a fluid-pressure cylinder and also to enable performing rolling in a stable state by reducing backlash between the housing and the roll chock of a rolling mill, with respect to the fluid-pressure cylinder and the rolling mill.
SOLUTION: A guide means is constituted by mounting hydraulic cylinders 21-28 in the housing 11, opposed to the roll chocks 12, 13, 16, 17, fitting these hydraulic cylinders 21-28 to a cylinder 32 fixed to the housing 11 through a liner 33 so that a thin plunger 40 is freely movable, also fitting the recessed part 42 of the thin plunger 40 to the center guide 38 of the cylinder 32 and a liner 54 for pressing each roll chock 12, 13, 16, 17 is connected to the tip part of the thin plunger 40.

摘要： PROBLEM TO BE SOLVED: To eliminate a water droplet from stagnated in a groove and to scarcely develop rust in a conical roller and a track plate by arranging the track plate with a groove in the upper side of a bearing and by arranging a disk track plate in the lower side of the bearing. SOLUTION: A track plate 11 with a groove 12 is provided in the upper side of the bearing as a movable side and a disc track plate 13 is provided in the lower side of the bearing as a fixed side. A conical roller 14 is arranged between the track plate 11 and the disk track plate 13 in such a state as loosely fitted in the groove 12. A bolt 13 is inserted in a long bolt hole 21 in the track plate 11 and threadly engaged in a screw hole of the track plate 13. The upper/ lower track plates 11, 13 are thus assembled beforehand as a unit by the bolt 23 and the track plate 11 with the hole is arranged in the upper side of the bearing so that a water droplet is prevented from stagnated in the groove 12 and the rust is scarcely developed in the conical roller 14 and the track plates 11, 13.

摘要： PURPOSE:To reduce a load on a radial bearing and to prevent damage by arranging a 1st radial bearing, a 2nd radial bearing and a thrust bearing in this order from the vicinity of the central part in the direction of a roll shaft toward the shaft end part in a roll chock. CONSTITUTION:When a rolled stock 50 is rolled, vertical and horizontal loads are borne by two sets of radial bearings 4, 6 in such a manner that a length between the point of application of a roll bending force and the neck of a work roll 1 is not enlarged and a length between the point of application of the bearing load of the radial bearing 4 on the neck part side and the point of application of the bearing load of the radial bearing 6 of the shaft part side is made larger than hereto fore so that biased load is decreased, and a thrust force acting in the direction of the roll shaft of the work roll 1 is borne by one set of thrust bearings 5. As a result, the load of the radial bearings is reduced.

摘要： PURPOSE:To permit the selective use of a shift roll and conventional roll and the reduction of a product cost by providing a work side bender block slidably with a housing. CONSTITUTION:The bender blocks 34, 34' are incorporated into the housings 31, 31' on the driving side D and work side W of a rolling mill and the bender block 35 is fixed to the housing 31. On the other hand, the bender block 37 is slidably fixed to the housing 31' and a liquid pressure cylinder 38 is disposed. A cylinder 38 is operated to move a cylinder block 37 and the block is pressed to the housing 31' by means of bolts 39 in the stage of using a shift roll 32. A projecting part 43 of a roll chock 42' is clamped by the bender block 37 in the stage of using the conventional roll 41. Since the selective use of the shift roll 32 and the conventional roll 42 is made possible by the above- mentioned method, the roll consumption is reduced. The cost is thus reduced.
