FIELD: metallurgy.
SUBSTANCE: required level of mechanical properties in manufactured hot-rolled plates of the chosen chemical analysis of steel is achieved due to regulation of finishing rolling beginning temperature in the range of 830±20°C, hot rolling end temperature equal to 820±15°C, as well as accelerated plate cooling beginning temperature of more than 780°C and accelerated plate cooling end temperature of 625±15°C.
EFFECT: providing identical improved mechanical properties, which are uniformly distributed across the plate section, which correspond to strength class K60.
