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.

摘要： PURPOSE:To flatly roll the rolling materials of various kinds of sizes and materials without requiring roll spares of multiple kinds of crown amounts by loosely fitting offcentered sleeves to both side parts and central parts of the backup rolls of the 4-stage rolling mill and providing rotating devices for controlling of the rates of offcenter to the roll bodies. CONSTITUTION:At the time of rolling a plate-form rolling material 1 by a work roll 2, sleeves 7, 8 are rotatably loosely fitted to the outside circumferences of both side parts and central part of upper and lower backup rolls 5. The central sleeves 8 are mounted with offcentering by e with respect to the revolving center of the backup rolls 5. When the rolls 5 are revolved by driving fine adjustment devices 16, the roll bodies 5 revolve about the center A of the roll bearings 12 and the center B of the central sleeves 8 deviate by e1. When rolling is done in this state and if the maximum deflection of the rolls 5 is equal to e1, the outside surfaces of the contact of the sleeves 7, 8 with the work rolls 2 become linerar irrespective of the deflections of the rolls 5 and the rolling material 1 is flatly rolled.

摘要： PURPOSE:To contrive the reduction of labors and improvement of the safety, by constituting as follows; the stool for rearranging work is set between the upper and lower push rolls, and the upper push roll is brought down until it is supported by the lower push roll, and the support rail is lifted up to the traveling wheel attached to the lower push roll, and the rail is traveled onto the rearranging truck which is then pulled out of the rolling mill. CONSTITUTION:The upper push roll is lifted up by the cylinder 7 installed on the frame 4, and the rail 17 is used in preparing the rearranging turck 16. Then, the rearranging stools 23a and 23b are set between the top carriage 11a and bottom carriage 12a, and the push roll is lifted up by the cylinder 19 installed on the frame 4 through the rail 14. Next, the rail 15 is set, and the upper and lower push rolls are pulled out of the mill through the wheel 13a of the bottom carriage 12a, and the rail 15 is removed; after that, the truck 16 is traveled. And then, above stated procedures are repeated for moving the remained rolls; hereby, the reduction of labors and improvement of safety can be realized.

摘要： PURPOSE:To obtain a uniform, fine ground surface in spite of variation of a roll diameter. CONSTITUTION:A cup shape grinding-stone 3 comes into contact with the surface of the roll 1 through its front face. The rotation axis O of the cup shape grinding stone 3 is offset by an offset amount (e) from the axis of the roll 1 and a contact line L is obtained. When the cup shape grinding stone 3 is reciprocated in the axial direction of the roll 1, the roll 1 is ground. The off set amount (e) is adjusted with variation of the diameter of the roll 1.
