摘要： A casting roll moving apparatus for a twin roll type continuous strip casting process is disclosed. The casting roll moving apparatus of the present invention is used with a twin roll type strip casting machine that produces a strip through a method in which, while high-temperature steel melt is supplied between twin rolls (1) which rotate in opposite direction, a large amount of heat is dissipated through the rolls by contact between the steel melt and the rolls, so that the steel melt is rapidly solidified. In the present invention, opposite ends of the rolls are automatically aligned, so that the recovery rate of the apparatus is increased, and a stable casting process is ensured. Furthermore, because friction of the apparatus is markedly reduced so that an even rolling force is ensured, a gap between the rolls is maintained constant. Thus, the thickness of a cast strip is maintained constant, and the problem of the occurrence of an uneven surface pattern is solved.

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.
