Abstract

982,231. Rolling. WESTINGHOUSE ELECTRIC CORPORATION. Sept. 20, 1963 [Sept. 21, 1962; April 29, 1963], No. 37076/63. Heading B3M. [Also in Division G3] A method of controlling the cross-section shape of a workpiece which is passed through one or more pairs of crowned rolls comprises predicting the pass screwdown setting for each pair of rolls, according to the desired incoming and delivery thickness of the workpiece and the mill characteristics, and passing the workpiece through the rolls when so positioned. For single stand reversing rolling, Fig. 1, thickness gauges 31 and 34, width gauges 35 and 33 and temperature gauges 36 measure parameters of a strip 32 and feed values to a computer 24. Information, such as roll speed frame 39, roll force frame 37, and roll position frame 28, the workpiece composition, desired delivery thickness from each pass and initial workpiece temperature is also fed to the computer, and a motor speed control 22 for the work rolls 12 and 14, and a screwdown position control 28 are actuated by the computer to control the rolling operation. Similarly, for a tandem rolling mill, Fig. 2, interstand computers 68 and 78 and a central computer 72 are fed with information from speed sensers 64 and 82, thickness gauges 58 and 74, temperature gauges 60 and 76 and an overriding X-ray thickness gauge 56 situated after the last stand, in order that the strip cross-section can be controlled. It is preferred that the final strip content be slightly thicker in its centre than at its edges in order to give it more stability whilst being rolled. Independent control of the serewdown mechanism at both ends of the rolls of a stand is possible, a number of gauges measuring the strip thickness across its width. Specification 982,232 is referred to.
