Claims (4)

1. Способ прокатки толстолистовой стали из полуфабриката в несколько рабочих операций, следующих друг за другом, с числом "n" проходов, различающимся в зависимости от желаемого конечного продукта, в одной или нескольких прокатных клетях, предпочтительно, в реверсивной клети горячей прокатки, отличающийся тем, что прокатку, начиная с прохода n-k, вплоть до прохода n-1 (причем k является порядковым числом, лежащим в диапазоне от 1 до n-1), осуществляют с более высокими обжатиями за проход в начале полосы (с меньшими толщинами материала), чем на конце полосы.1. A method of rolling plate steel from a semi-finished product in several successive operations, one after the other, with the number of "n" passes, varying depending on the desired end product, in one or more rolling stands, preferably in a reversible hot rolling stand, characterized in that rolling, starting from passage nk, up to passage n-1 (where k is an ordinal number lying in the range from 1 to n-1), is performed with higher reductions for the passage at the beginning of the strip (with smaller thicknesses of material), than at the end of p olos. 2. Способ по п. 1, отличающийся тем, что уменьшение обжатий за проход или увеличение толщины материала осуществляют от начала полосы к концу полосы линейно по всей длине полосы. 2. The method according to p. 1, characterized in that the reduction of crimps per passage or increase the thickness of the material is carried out from the beginning of the strip to the end of the strip linearly along the entire length of the strip. 3. Способ по п. 1, отличающийся тем, что уменьшение обжатий за проход или увеличение толщины материала от начала полосы к концу полосы осуществляют не линейно, а согласно другой, заранее заданной математической функции, по всей длине полосы. 3. The method according to p. 1, characterized in that the reduction of the compression during the passage or the increase in the thickness of the material from the beginning of the strip to the end of the strip is carried out not linearly, but according to another, predetermined mathematical function, along the entire length of the strip. 4. Способ по одному или нескольким пп. 1-3, отличающийся тем, что разница толщин материала между началом полосы и концом полосы убывает с увеличением числа проходов, в соответствии с уменьшающейся средней толщиной полосы. 4. The method according to one or more paragraphs. 1-3, characterized in that the difference in the thickness of the material between the beginning of the strip and the end of the strip decreases with an increase in the number of passes, in accordance with a decreasing average thickness of the strip.
