Abstract

1294414 Rolling NIPPON KOKAN KK 19 April 1971 [7 March 1970] 23718/71 Heading B3M The variation in the tension of a metal strip when the gauge of the strip is to be varied at a high rolling speed in a continuous tandem rolling mill is minimized by varying the rolling speeds of a particular mill stand and of succeeding and/or preceding mill stands by the same increment as each other when a gauge varying part of the metal strip reaches the particular mill stand and then successively varying the rolling speeds of the succeeding and/or preceding mill stands by the same increment as each other thereby finally varying the rolling speeds of all mill stands to the speeds required to produce a strip of a given gauge.
