Abstract
Способ производства рулонов горячекатаной низколегированной стали толщиной 16.0÷20.0 мм, включающий выплавку, разливку стали с получением кристаллизованного сляба, его горячую прокатку в клетях широкополосного стана с охлаждением водой поверхности полосы в межклетевых промежутках и на отводящем рольганге с последующей смоткой в рулон, отличающийся тем, что выплавляют сталь, с содержанием углерода 0.14÷0.22%, кремния 0.40÷0.80%, марганца 0.80÷1.50%, при этом для полос толщиной от 16.0 до 17.9 мм включительно температуру конца прокатки в черновой группе устанавливают равной 1000÷1040°С, подачу воды на поверхность полосы начинают с третьего межклетевого промежутка, при этом скорость охлаждения полосы в чистовых промежутках стана определяют из выражения Vохл=0,25·e2,12·Vпр, где Vохл - скорость охлаждения поверхности полосы в i-м чистовом межклетевом промежутке, град/с; Vпp - скорость прокатки в 1-й чистовой клети, м/с, кроме того, прокатку в первых четырех клетях чистовой группы стана осуществляют с единичным относительным обжатием не менее 12%, а для полос толщиной от 18.0 до 20.0 мм включительно температуру конца прокатки в черновой группе устанавливают равной 980÷1020°С, при этом скорость охлаждения полосы в чистовых промежутках стана, начиная с третьего, определяют из выражения Vохл=0,28·e2,24·Vпр, где Vохл - скорость охлаждения поверхности полосы в i-м чистовом межклетевом промежутке, град/с; Vпp - скорость прокатки в i-й чистовой клети, м/с, кроме того, прокатку в первых четырех клетях чистовой группы стана осуществляют с единичным относительным обжатием не менее 15%. A method for the production of coils of hot-rolled low-alloy steel with a thickness of 16.0 ÷ 20.0 mm, including smelting, casting of steel to obtain a crystallized slab, its hot rolling in the stands of a broadband mill with water cooling of the strip surface in the intercellular spaces and on the discharge roller table, followed by winding into a roll, characterized in that steel is melted, with a carbon content of 0.14 ÷ 0.22%, silicon 0.40 ÷ 0.80%, manganese 0.80 ÷ 1.50%, while for strips with a thickness of 16.0 to 17.9 mm inclusive, the temperature of the end of rolling in the roughing group poured equal to 1000 ÷ 1040 ° C, water supply to the strip surface begins from the third inter-span gap, while the cooling rate of the strip in the finishing gaps of the mill is determined from the expression Vcohl = 0.25 · e2,12 · Vpr, where Vcohl is the cooling rate of the strip surface in the i-th finishing inter-span gap, deg / s; Vpp is the rolling speed in the 1st finishing stand, m / s, in addition, rolling in the first four stands of the finishing group of the mill is carried out with a single relative compression of at least 12%, and for strips with a thickness of 18.0 to 20.0 mm inclusive, the temperature of the end of rolling in the draft group is set equal to 980 ÷ 1020 ° C, while the cooling rate of the strip in the finishing intervals of the mill, starting from the third, is determined from the expression Vcohl = 0.28 · e2.24 · Vpr, where Vcohl is the cooling rate of the strip surface in the ith fine inter-span gap, degrees / s; Vпр - rolling speed in the i-th finishing stand, m / s, in addition, rolling in the first four stands of the finishing group of the mill is carried out with a single relative compression of at least 15%.
