Claims (1)

Способ производства рулонов горячекатаной трубной стали, преимущественно с содержанием углерода 0,07-0,14% и толщиной 10-16 мм, включающий нагрев сляба под горячую прокатку, прокатку его в черновой и чистовой непрерывной группах клетей широкополосного стана с межклетевым охлаждением поверхности полосы водой и с температурой конца прокатки 800-840°С, охлаждение полосы водой на отводящем рольганге с последующей смоткой в рулон, отличающийся тем, что температуру конца прокатки устанавливают для полос толщиной от 10 до 12 мм включительно 815-845°С, для полос толщиной свыше 12 до 16 мм включительно устанавливают 760-800°С, при этом в межклетевых промежутках чистовой группы стана регулируют интенсивность охлаждения поверхности полосы путем изменения скорости ее охлаждения, которую определяют из выраженияA method for the production of coils of hot-rolled pipe steel, mainly with a carbon content of 0.07-0.14% and a thickness of 10-16 mm, comprising heating a slab for hot rolling, rolling it in rough and finish continuous groups of stands of a broadband mill with intercell cooling of the strip surface with water and with a temperature of the end of rolling 800-840 ° C, cooling the strip with water on the discharge roller table, followed by winding into a roll, characterized in that the temperature of the end of rolling is set for strips with a thickness of 10 to 12 mm inclusively 815-845 ° C, for los from 12 to 16 mm inclusive mounted 760-800 ° C, with a finishing mill interstand spacing group regulate the intensity of the cooling of the strip surface by changing the speed of its cooling, which is determined from the expression V=1,94·Ln(N)+3,52,V = 1.94 Ln (N) +3.52, где V - скорость охлаждения поверхности полосы, град/с;where V is the cooling rate of the strip surface, deg / s; N - номер межклетевого промежутка чистовой группы стана.N is the number of the inter-span gap of the finishing group of the mill.
