摘要： In a multi-roll table ring-rolling mill and method, a mandrel roll can be switched from a rolling state into a free-running state, when a predetermined ring diameter is reached, even if the roll gap minimum has not yet been reached, in order to improve the size accuracy of the rolled rings. A mandrel roll table rotating about a mandrel table axle is used, along with at least one main roll rotating about a main roll axle and first and second mandrel rolls that are mounted in the mandrel roll table, and a relief device to relieve at least the first mandrel roll of rolling forces. The main roll axle and the mandrel roll table axle are mounted in unchangeable manner and eccentric to one another, at least during the rolling process. The relief device acts independent of the main roll axle and the mandrel roll table axle are eccentric to one another.

摘要： A signal which is dependent solely on the disturbance variable is selected by means of a filter and fed to a disturbance detector. This disturbance detector simulates the steady and alternating component (sine component) of the selected signal, as well as a signal (cosine component) phase-leading by 90.degree. with the latter signal. The correction signal required to exactly compensate for the disturbance variable is determined from the sine and cosine component of the periodic disturbance signal component by means of frequency-controlled function generators and a complex phasor calculation.

摘要： A rolling load signal is detected during a few rotations of a top and a bottom backup roll at different detection time points at which the top and bottom backup rolls are out of phase from each other and then are analyzed by Fourier analysis so as to detect the amplitudes and phases of the eccentricity of the top and bottom backup rolls separately, whereby the roll gap is controlled and the separately detected eccentricity of the top and bottom backup rolls is thus obtained. Even when there is a difference in roll eccentricity frequency between the top and bottom backup rolls and even when external disturbances exist due to the aging of the roll eccentricity and to the estimated errors of the mill constant M and the plasticity coefficient Q of a piece of metal to be rolled, the roll eccentricity can be suitably adjusted so that the roll eccentricity can be detected with a high degree of accuracy and then eliminated.

摘要： A gage control system for a rolling mill for compensating for variation in the thickness of rolled material due to variations in the rolling load or pressure. In the system, the roll eccentricity frequency produced by the eccentricity of the rolls is detected and utilized for softening the effective rigidity or stiffness of the mill, that is, weakening the apparent mill modulus by control means according to the frequency of roll eccentricity. To this end, a positive feed back path including an eccentricity control unit is provided in parallel with a feed back path of the rolling pressure signal of a gage control circuitry of the so-called BISRA system. The eccentricity control unit serves to detect the roll eccentricity on the basis of a correlation principle and compensate for or cancel the effects of the feed back of the rolling pressure upon the occurrence of the roll eccentricity.

摘要： The present invention relates to a method and an apparatus for detecting a roll eccentricity element of a rolling mill, which is occurred by the difference between a rotation center and a geometric center of a roll. The present method for detecting a roll eccentricity of a rolling mill comprises the steps of: inputting data with respect to a rolling load from the rolling mill, a pulse generating signal from a pulse generator, input and output signals of the steel plate, respectively; determining whether input signal of the steel plate and marker pulse signal of the pulse generator are being inputted; storing the rolling load of the rolling mill corresponding to respective sample pulse signals of the pulse generator in a buffer; calculating alterations of the rolling load by subtracting average rolling load from the rolling load being stored in the buffer; detecting eccentric fundamental wave and radio frequency elements by performing non-linear curve fittings to alteration signal of the rolling load; and determining whether output signal of the steel plate is being inputted and when the output signal is being inputted, detecting procedure is terminated and when the output signal not being inputted, it is returned to the step of storing and the subsequent procedure is repeatedly performed. The present invention is capable of accurately detecting roll eccentricity elements to eccentric fundamental wave and radio frequency elements, using a pulse signal of the pulse generator and a rolling load signal of a load cell. Also, such detection of the roll eccentricity can be performed in reliability and durability, even in severe working conditions of the rolling mill.
