FIELD: metallurgy.
SUBSTANCE: in the obtained hot-rolled sheets of the selected chemical composition of steel is reached via temperature regulation of hot rolling crude stage within 980÷1100°C with semi-finished rolled product thickness for finishing stage 140÷170 mm, the beginning of rolling finishing stage within 780÷820°C and the end of hot rolling 780÷810°C. Moreover the temperature of sheet accelerated cooling end is taken 560÷600°C.
EFFECT: provision of tube range 26-28 mm thick in hot-rolled products from micro-alloyed steel with equal mechanical properties by sheet section corresponding to X60 strength grade.
