摘要： PROBLEM TO BE SOLVED: To provide a table roll device in which the workability in the line is improved without extending the length of equipment.
SOLUTION: A steel strip which runs between a cold-rolling mill 1 and a winding reel 4 of the main devices which is positioned in the middle of a steel strip processing line is supported with this table roll device 2. The table roll device 2 can be moved vertically with a ascending and descending cylinder device 3 so that its height is adjustable from the height of the pass line (PL) at the processing of the steel strip to the height of the floor level (FL) where the processing line is installed.

摘要： PURPOSE:To manufacture a strip having a superior surface quality by providing supporting bases which are movable in the direction orthogonally crossed with the advancing direction of the strip on both sides of press base frame by which belts are pressed towards a pass line. CONSTITUTION:On each upper and lower side partitioned by the pass line A-A, a pair of left and right reels 15, 16, and a belt 20 which is stretched between this pair of left and right reels, and the press base frame 4 by which the belt is pressed towards the pass line are provided. The supporting bases 5 are provided movably to the direction orthogonally crossed with the advancing direction of the strip on both sides of the press base frames 4. The belts 20 are made of a permeable material, plural sucking ports are provided in the direction orthogonally crossed with the advancing direction of the strip on the press base frames 4 and the supporting bases 5, and the sucking ports are connected to discharge ducts 11. Consequently, the uneven wear and damage to the belts are prevented, and the deterioration of the strip quality which is due to the foreign matters sticking to the strip again after once removed is prevented by sucking the foreign matters by a vacuum suction.

摘要： To improve the productivity of the cold rolling facility by providing the cold rolling facility with a strip wiper free of dust and foreign matters suitable for high-speed rolling. The wiping ability was greatly improved by floating and supporting the wiper roll by the static pressure bearing of air of two-pocket type, and by variably adjusting the load range of the floating force in response to the plate width. At high-speed rolling exceeding 700 m/min which was incapable with the conventional roll wiper or tube wiper, the productivity of the cold rolling facility and the surface quality of the strip were greatly improved by applying to the cold rolling facility the wiping device whose wiping ability is equal to or better than the tube wiper at low speeds, and its effect is very large.

摘要： In a rolling mill facility having a strip shape detection equipment, making it possible to measure the strip shape of metal strip after rolling easily and with a simple construction. In a rolling mill facility consisting of a single or plural rolling mills(4)having a pair of top and bottom work rolls (2 and 3) that roll strip steel (1) and strip shape detecting devices (5 and 6) installed at least on one side of the inlet and outlet sides of the rolling mill (4), said strip shape detecting devices (5 and 6) consist of a single roller (14) on which the metal strip (1) gets wound, and at least two bearing boxes (9A and 10A) on one side or four bearing boxes on both sides with said bearing boxes (9A and 10A) supporting the roller in a free-to-rotate manner, and at least two load cells(11A and 12A)on one side or four load cells on both sides for measuring the supporting load of each of the bearing boxes (9A and 10A). From the load values measured by these load cells (11A and 12A), the tension distribution of the strip (1) is computed, and that tension distribution is converted into the strip shape of the strip.

摘要： In a cluster type split housing type rolling mill, the plate thickness control capability is improved by suppressing decrease in the mill rigidity as small as possible. Two pass line adjusting mechanisms (15, 16) are arranged between the operating side and the driving side outer housings (10, 11) in the upper side of the top inner housing (8) to form a top side supporting means for supporting the upper side of the top inner housing (8) to the outer housings (10, 11) in the operating side and the driving side each at two points in the front side and in the back side with respect to a pass direction using rocker plates of these two pass line adjusting mechanisms (15, 16). Further, two press-down cylinders (17, 18) are arranged between the operating side and the driving side outer housings (10, 11) in the lower side of the bottom inner housing (9) to form a bottom side supporting means for supporting the lower side of the bottom inner housing (9) to the outer housings (10, 11) in the operating side and the driving side each at two points in the front side and in the back side with respect to the pass direction using rocker plates of these two press-down cylinders (17, 18).
