Abstract
1293872 Rolling mills NIPPON KOKAN KK 18 Feb 1970 [21 Feb 1969] 7685/70 Heading B3M A rolling mill is controlled by a computer which is fed with a number of groups of operating schedules for the mill, the schedules being defined so that the computer can calculate reference schedules for each group in accordance with linear equations. Each reference schedule is calculated to result in a rolled product having desired properties within a given range. The parameters of the mill, such as workpiece thickness, temperature, and rolling load are controlled by the computer in response to their deviations from the corresponding values in the reference schedules. The method can be applied to the various stands of a continuous mill, or to successive passes in a reversing mill. The initial settings for the mill parameters can be updated during a rolling operation in response to the measured values of the parameters.
