摘要： PURPOSE:To reduce the deflection of work rolls in the horizontal direction end to enable high-rigidity support against horizontal bend by providing support rollers with which both sides of the body part of work rolls are respectively supported on the inlet and outlet side of rolled stock and position adjusting devices with which the offset quantity of work rolls can be adjusted. CONSTITUTION:The work rolls 1 are made to be arbitrarily movable in the pass direction and both sides of the body part of roll in the area outside the max. width of the rolled stock 11 on both of the inlet and outlet side of the rolled stock of the work rolls 1 are supported by arranging the support rollers 14. Then, by making the offset quantity of the work rolls 1 adjustable by providing the position adjusting devices 5 on those support rollers 4, the work rolls are situated in a dynamically balanced position due to rolling load, driving tangent force and the difference of tension in the back and forth direction, etc. Further, the high-rigidity support against the horizontal bend of the work rolls 1 is made possible and disturbance load is prevented and rolling with which the shape of the rolled stock 11 is stabilized can be performed by arranging the bearing boxes 8 of the work rolls 1 with clearance in the horizontal direction with adjacent members.

摘要： PURPOSE:To make easy the attaching and detaching or the transportation by crane of a chock by constituting a roll by the device to pull out the roll, the truck to move with placing on board the roll each unit body and the frame to go in and out of the attaching and detaching device. CONSTITUTION:Work roll 4 and intermediate roll 5 are pulled out of mill 1 by drawing device 3 onto recombination truck 2. The upper and lower work rolls 4 only are placed on the chock attaching and detaching truck 8 via the guide frame 6 fixed by the drawing device 3 then. In case of placing the intermediate roll 5 as simple substance on the chock attaching and detaching truck 10 of the intermediate roll then the upper and lower intermediate rolls 5 as well are placed as simple substance on the chock attaching and detaching truck 10 via the guide frames 6, 7, 9 by the drawing device 3 similarly. In case of attaching and detaching the chock from the roll a chock 15 is supported with frame 19 by jack 20 by stroking cylinder and by moving to the lower side of the chock 15 the frame 22 to support air bearing 21 on its upper part. The chock 15 is attached and detached from the roll by moving ring 16.

摘要： PURPOSE:To enable various rearranging patterns by providing respectively rails to be exclusively used to work rolls and intermediate rolls to assure space and providing a moving machanism to be commonly used. CONSTITUTION:Rolls 6, 7 are removed by a push puller 13 in the case of rearranging upper and lower work rolls 6, 7. The position of a side shifting table is then side-shifted. The engagement between the push puller 13 and upper and lower intermediate rolls 5, 8 is released, and the puller 13 is inserted into a rolling mill 1 by means of cylinders 14, 15. The puller 13 can force the fresh upper and lower work rolls 6, 7 into the mill 1 without contact with the rolls 5, 8. An oil pressure is finally applied on the hook cylinder to remove an upper work roll hook 16 and a lower work roll hook 17 from the roll 6 and the roll 7 respectively and the cylinders 14, 15 are contracted to return the puller 13 to the home position. The roll rearrangement is thus completed.

摘要： PURPOSE:To maintain a rolled strip at high temp. and to reduce the thermal energy used in an annealing furnace by mounting wipers to the inlet side and outlet side of a rolling mill in the rear part of tandem mills, and inhibiting the splashing of coolant upon the strip. CONSTITUTION:In a suitable number of rolling mills in the rear part of tandem mills, wipers 19, 20, 21, 22 are disposed on the inlet and outlet sides on the outside circumferences of work rolls 30 in such a way that their leading ends contact with the rolls 30 slidably in the positions apart from a strip 14. An air wiper 28 is installed to the guide 17 of the wiper 21 on the upper side out of these, to jet air onto the strip 14. Then, despite the splashing of a coolant on the work rolls 30, water is shut off with the wipers 19-22 as against the strip 14 located between the wipers 19-22, and the water stuck to the roll 30 surfaces is wiped off as well. Hence, the strip 14 out from the rolling mills maintain a high temp. state. This heat is utilized for part of the thermal energy for annealing.

摘要： PURPOSE:To reduce wear of reinforcing rolls and to increase rolling amounts up to roll changing by using asymmetric rolls in a rolling mill and reversely changing their position at proper times. CONSTITUTION:As for roll changing of work rolls 2, 3 having asymmetric profile such as S-shape, etc., the rolls 2, 3 are reversed in a combined position shown by the broken lines. A max. loaded part between the rolls 2, 3 and rein forcing rolls 1, 4 is moved from a position 5 to a position 5' by reversing the combined position shown by continuous lines to a position shown the broken lines and performing rolling. Thus, surface wear of the rolls 1, 4 is distributed and is symmetrized. Hence, wear of the rolls 1, 4 is reduced because the rolls 1, 4 are made of a comparatively soft material. Therefore, a rolling amount to a next changing time of the rolls 1, 4 is increased.

摘要： PURPOSE:To obtain a titled device capable of measuring the tension of a material accurately and detecting the meandering even if its quantity is small by constituting the device wherein the load of a roll is received by load cells disposed at the inside of bearing parts through a frame which connnects the bearing parts located at both sides of the roll. CONSTITUTION:A tension meter device of a rolling mill is constituted by pivotally supporting a bracket 13 attached to a frame 10 which connnects roll chocks 3, 3 located at both sides of a roll 2 of rolling mill, and a bracket 15 on a fixed frame 16, at the position just below a pass center C, and installing a pair of load cells 1, 1 at both sides of the center C and at the inside of said chocks 3, 3. By said device, the tension of a material to be rolled is accurately detected by receiving a load loaded from the material 8 on the roll 2 by the load cells, 1, 1 and also even the small quantity of material meandering is detected basing on the difference between the loads of load cells 1, 1 located at both sides when the material 8 deviates from the pass center C and meanders.
