FIELD: process engineering.
SUBSTANCE: proposed method comprises strip rolling with acceleration at continuous rolling mill stands. Invariable degree of recrystallisation over strip length, given reduced interval between strains, becomes possible due to accelerated rolling that allows increasing rolling termination temperature from the strip front end to rear end by 3-30°C per every 100 m of the strip.
EFFECT: higher efficiency of hot-strip mill and stabilised mechanical properties on major part of hot-rolled strip.
