摘要： PURPOSE:To prevent the deterioration of the strength of a roll supporting shaft for a rolling mill by a method wherein lubricating oil is supplied from one end of a double hollow part provided at the central part of the roll supporting shaft and is circulated in a bearing while it is discharged from the other end of the hollow part. CONSTITUTION:A lubricating oil outflow preventing cover 8 is attached to both ends of an outer shaft 7 and the central part of a fixed shaft 4 is made hollow. Other hollow tube 10 is inserted into the hollow part 9 and is fixed thereto so as to form the double hollow configuration having a uniform section with respect to the axial center thereof. The hollow part 9 of the fixed shaft side is utilized for an oil path as an outer hole while the same of the hollow tube 10 is utilized for the oil path as an inner hole respectively, therefore, the section of the roll supporting shaft becomes uniform and the deterioration of the strength thereof may be prevented.

摘要： PURPOSE:To prevent the generation of edge drops, etc. and to obtain products of good shapes by forming split type eccentric rolls for the backup rolls of multistage rolling mills and loading roll bending force upon the metal chocks of intermediate rolls. CONSTITUTION:In multistage cluster rolling mills, backup rolls 4 are split to plural rolls in the direction intersecting orthogonally the axial direction of stationary shafts 5a and the bearings of the split rolls are off-centered. Crowns are adjusted by the entire part of the rolls 4. Crowned parts are provided in the end parts of upper and lower work rolls and intermediate rolls 3 and are moved symmetrically in an axial direction. Further, means 11, 12 for loading roll bending force are provided to metal chocks 7 for the intermediate rolls to transmit the rugged shapes formed by the backup rolls effectively to the work rolls 2. By such mechanism the products having less generation of edge drops, etc. are obtained.

摘要： PURPOSE:To make a motor of an excessively large capacity unnecessary, and to selectively drive both or either one of an upper and lower rolling roll group, by constituting a power transmission route of 4 ways, by a switching operation for a clutch mechanism. CONSTITUTION:The sleeves of the clutch mechanisms 5, 5 respectively provided in the input shafts I1 and I2 are shifted by an action of a hydraulic cylinder 6 through a lever 7, etc.; hereby, the projections 9, 9 engaged with the pinions I1a and I2a. The outputs P1, P2 of two motors 1, 1' are integrated in a single output shaft O1, and the output is not transmitted to another output shaft O2. The outputs P1, P2 of two motors 1, 1' are separately transmitted to the output shafts O1, O2 by operating the clutch mechanism 5 and the upper and lower rolling rolls of concerned rolling mill are driven at the same time. By another operation, the outputs P1, P2 are integrated in a single output shaft O2, or the outputs P1, P2 are transmitted to the output shafts O2, O1. These 4 ways of power transmission route are selected by operating only the clutch mechanism according to the purpose.

摘要： PURPOSE:To cut a spiral pipe in lengths with accuracy by running a cutter carriage at the same speed as that of a spiral pipe and by cutting this pipe with a cutter while running. CONSTITUTION:A spiral pipe 1 manufactured by the pipe manufacturing facility runs in succession rolling on a bearer 30. When the pipe 1 gets to the prescribed length, a movement measuring device (PLG) on a carriage 32 detects it. Then, a running start order is given to a cutter carriage 33 in readiness on tracks 31'', 31''' behind a length-measuring machine A in the running direction, and the carriage 33 is controlled in the same way as the carriage 32 is, starting running on the tracks 31'', 31''' at the same speed as that of the pipe 1. At the same time, a cutter B on the carriage 33 is made ready for cutting and then makes a cut. In this way, the pipe 1 can be cut in lengths with accuracy.

摘要： PURPOSE:To obtain a titled apparatus that can perform strong pushing of a material to be rolled by providing pinch rolls that pinch, drive and advance the material to be rolled and guides that prevent buckling of the material to be rolled and supplying coolant to the guides. CONSTITUTION:Pinch rolls 4, 5 and guides 2, 3 are provided in the housing 6 on the stand 7, and the pinch rolls 4, 5 are driven by a fluid pressure cylinder 8 or an electric motor and the material to be rolled 1 is pinched and pushed into a rolling mill which is small and having insufficient power to bite by itself such as work rolls 12, 13 of a multistages cluster mill 11. Following above-mentioned pinch rolls 4, 5, guides 2, 3 are provided to prevent occurrence of buckling even when pushing force is made larger. The distance between inner walls of the guides 2, 3 is made as small as possible. At the same time, roll coolant 9, 10 or air is spouted from numerous holes provided on the face of inner wall to prevent buckling by reducing contact resistance with the material to be rolled 1.

摘要： PURPOSE:To improve the productivity without stopping the whole line, by performing sheet joint welding of strip at a reduced line speed. CONSTITUTION:At the jointing of strips 2, 7, the line speed is changed to a welding speed according to the thickness of the strips 2, 7 from a normal running speed by the order from a speed controlling device to a pinch rolls 3 and a main driving device 11. At the same time, a sheet joint welding device 5 travels in synchronizing with the change of line speed by a carriage 5a in the feeding direction of the strips 2, 7. After completing the welding of strips 2, 7 by the device 5, the speed controlling device returns the line speed to the normal running speed. Then the jointed strip is sent to a spiral pipe foming equipment.

摘要： PURPOSE:To reduce the number of rolling stands, simplify the titled installation and to improve productivity by making the entire process continuous and using extra dissimilar diameter rolling mills in cold rolling cold rolled steel plates or surface treated steel plates. CONSTITUTION:After a rolling material S supplied through an uncoiling reel 1, a welding macine 2 and a descaling device 3 is cold rolled with dissimilar diameter rolls 4, it is annealed in a continuous annealing device 6, and is further rolled at the skin-pass draft corresponding to purposes with a skin pass rolling mill 7 and is coiled on a coiling reel 8. A cold rolling process 4 and a continuous annealing process 6 or the entire processes are made continuous, whereby the coiling process on the way is saved. In addition, the extra dissimilar diameter rolling mills permitting one pass high screw down are used in place of conventional cold rolling stands, whereby the number of rolling stands is reduced and the cost of equipment is lowered.

摘要： PURPOSE:To prevent generation of roll marks with a rolling mill having plural divided backup rolls by making the diameter at both ends of the divided rolls smaller than the diameter in the central part. CONSTITUTION:Backup rolls 10 which contact with a pair of intermediate rolls 3a, 3b of a rolling mill are constituted of plural divided rolls 10 and other backup rolls 11 are constituted of plural divided rolls 11a or 11b. The rolls 10a, 10b, 11b have the drum shape in which the diameter (d) at both ends is smaller than the diameter D at the center and the outside circumferential surface is gently formed. If a material 1 to be rolled is rolled with such rolling mill, the rolls 10a, 11a, 11b that contact with the rolls 3a, 3b have the drum shape and therefore the exertion of a large face pressure only on the outside circumferential surface of the rolls 3 in contact with the ends of the divided rolls as in the prior part is obviated. The generation of stripe-shaped roll marks on the outside circumferential surface of the rolls 3 is thus obviated and no roll marks are formed on the rolled material 1.

摘要： PURPOSE:To improve the biting of a rolling mill and to prevent work rolls from producing flaws by providing rolls for processing the tip of strip into a taper shape and a device for traversing the rolls in the width direction of the strip. CONSTITUTION:A strip 1 is fed in the arrow direction by upper and lower pinch rolls 2a, 2b while being guided by a side guide 3a, and is fixedly held by a clamp 3b after being bitten by rolls 8a, 8b of a rolling mill. Thereafter the tip of strip 1 is roll-formed into a taper shape by traversing a mill housing 7 in the lateral direction of the strip 1 while rotating the rolls 8a, 8b.
