GENERAL ASPECTS OF ROLL COOLING FOR HOT COLD

The so-called selective roll cooling is applied mainly for cold rolling mills to control the asymmetrical flatness deviations the strip width. There are furthermore across applications for special cast-rolling mills for narrow-gauge hot strip production. Normally, two rows of nozzles are used in one header.
