Abstract
1,264,876. Rolling mills. NIPPON KOKAN K.K. 21 May, 1969 [21 May, 1968], No. 25945/69. Heading B3M. A method of controlling a tandem strip rolling mill, suitable for rolling strips of different gauges welded end to end, includes predetermining a pattern of variation of peripheral roll speed with respect to strip gauge changes, detecting variations in the roll gap of the mill, and using the detected variations to control the peripheral roll speed to keep the interstand tension constant in order to provide a constant strip gauge. The method is suitable for a continuous mill, Fig. 8, which employs an on-line computer 75. The pattern of variation of roll speed is stored as a programme in the computer so that the computer can control the screwdowns 14-18 of the stands and speed regulators 51 and 53-56 associated with Ward-Lenoard system for the stands. X-ray gauge meters 8 and 9 are also used. The mill can be provided with further -sets of measuring instruments such as tension meters 10-13, Fig. 12, X-ray gauges following each stand, or load cells associated with each stand. The sets can be used singly or in combination to increase the speed and accuracy of rolling. Small feedback loops 65-68 may be used in combination with the tension meters.
