摘要： PURPOSE:To minimize the cropping quantity of a sheet bar, by providing a crop- shape discriminating device to the place just before a crop shear in rough rolling a slab, and feeding back the detected result of crop-shape to a press forming device to control the pre-forming conditions of a succeeding slab. CONSTITUTION:After heating a slab 4 to a prescribed temperature in a heating furnace 2, the slab 4 is passed through a pre-forming device 5 and is broadside rolled by a vertical scale breaker 6 and plural vertical rolls 8, 12 and horizontal rolls 10, 13. The dimensions of a broadside rolled sheet bar 22 are detected before cutting it by a crop shear 14, to feed back the detected value LEO to a press pre-forming device 5 so as to make LE=LEO, LC=LEO when the length of a central part of the width of a fish tail 16 is represented by LC and the length of a round part of the width end is represented by LE. The cropping quantity of a crop-shape formed at the end part of a sheet bar is minimized, and the yield of a sheet bar is improved.

摘要： The present invention provide: a method of controlling operation of a tandem rolling mill which enables large reduction rolling in the latter-stage stand of the tandem rolling mill that is necessary for manufacturing fine-grained steel and the like; and a method of manufacturing a hot-rolled steel sheet.
The method of controlling operation of a tandem rolling mill comprises: a first step of determining a sheet thickness on an exit side of each stand in rolling a constant portion of the material to be rolled; and a second step of determining a sheet thickness on the exit side of each stand in rolling a front end portion of the material to be rolled, such that the pre-tightening load becomes a set value or less; the material to be rolled is rolled to have the exit side sheet thickness determined in the second step, until at least the front ent portion of the material to be rolled is fed into each of the stands; the constant portion of the material to be rolled is rolled by the (N-m+1)-th stand to the N-th stand to have the exit side sheet thickness determined in the first step; and the sheet thicknesses on the exit sides of the (N-m+1)-th stand to the N-th stand determined in the second step are larger than the sheet thicknesses determined in the first step.
The method of manufacturing a hot-rolled steel sheet comprises the step of rolling a steel sheet by using a row of hot finishing mills the operation of which is controlled by the above method.

摘要： The aim of the invention is to mill a strip-shaped rolling stock (8) that is provided with a leading edge (14) in a rolling mill. Said aim is achieved by a rolling mill comprising a roll stand (1) with working rolls, a roll train (2) located at the feeding end of the roll stand (1), and a control device. The working rolls form a roll gap. The control device triggers the roll stand (1) such that the working rolls rotate at a certain peripheral speed while triggering the roll train (2) located at the feeding end of the roll stand (1) in such a way that the leading edge (14) of the strip-shaped rolling stock (8) reaches the roll gap at a feeding speed that is greater than the peripheral speed. The control device adjusts the peripheral speed and the feeding speed to each other in such a way that a potential angled position of the leading edge (14) relative to the roll gap is at least reduced as a result of said adjustment.

摘要： The invention relates to a mill train (1) for milling a strip-type product to be milled (10). Said mill train comprises a number of roll stands (2) which are successively arranged in a milling direction (x) and which can be respectively pivoted about a rotational axis (18) which is essentially perpendicular to the milling direction (x). The aim of the invention is to maintain a belt run which favours a pre-determined milling result, in an especially simple and reliable manner. According to the invention, a control value (S) is pre-determined for the pivoting angle of a roll stand, or of each roll stand (2), according to the determined contour of the strip end (30) of a product (10) which has already been milled. According to the invention, additional control elements can also be used.

摘要： A method for controlling the dimensions of an elongated material (6) rolled in a rolling mill comprising at least three mill stands (1, 2, 3) arranged after each other, wherein a first stand (1) is arranged upstream of a second stand (2), which is arranged upstream of a third stand (3). Each of said stands comprises two spaced rolls (4, 5). Said elongated material is fed between the rolls of each stand by rotating the rolls, wherein an interstand tension is controlled between at least two of said stands. A tail (7) of the rolled material (6) is detected leaving the first stand, and after said detection, a back tension control between the first (1) and the second stand (2) is switched off for the period while the tail (7) travels between the first stand and the second stand, and a front tension control between the second (2) and the third stand (3) is switched on for the period while the tail travels between the first stand and the second stand.

摘要： The invention relates to a method and an installation for hot-rolling strips using a reversible Steckel rolling frame (8), each side of which is equipped with a respective furnace coiler (9, 10) and a driving mechanism (17, 18), provided between the furnace coiler (9, 10) and Steckel rolling frame (8). The aim of the invention is to crop particularly thin, hot strips. To achieve this, the strip is cropped during the reversible rolling process by a single pair of flying cropping shears (20), positioned between one of the driving mechansims (17) and the Steckel rolling frame (8). Said cropping shears comprise in particular a drum blade.
