Description

Известен способ прокатки листов, преимущественно толстых, включающий редуцирование исходных сл бов по щирине, порезку редуцированных сл бов, промежуточный их подогрев и дальнейщую прокатку.There is a known method of rolling sheets, mainly thick ones, including the reduction of the initial slabs along the width, cutting of the reduced slabs, their intermediate heating and further rolling.

Предлагаемый способ отличаетс  тем, что предварительно редуцированные сл бы перед окончательной прокаткой подвергают разбивке ширины.The proposed method is characterized in that the previously reduced slabs undergo a breakdown width before the final rolling.

Это позвол ет снизить анизотропию свойств прокатанного листа.This makes it possible to reduce the anisotropy of the properties of the rolled sheet.

На фиг. 1-4 показана последовательность операций при прокатке листов, по предлагаемому способу.FIG. 1-4 shows the sequence of operations when rolling sheets, according to the proposed method.

Прокатку листов производ т, например, из непрерывнолистовых сл бов. Последовательно осуществл ют следующие технологические операции: редуцирование исходных сл бов (см. фиг. 1) дл  уменьшени  их первоначальной ширины А в 1,25-3,0 раза до получени  промежуточной ширины Б (см. фиг. 2); порезку редуцированных сл бов на .размер В; промел уточный подогрев, кантовку; прокатку в уширительной клети до требуемой ширины листа Г (см. фиг. 3) и дальнейшую нрокатку в продольном пли поперечном направлении относительно исходных сл бов до получени  готовой продукции шириной Г и длиной Д (см. фнг. 4).Sheet rolling is performed, for example, from continuous sheet slabs. The following technological operations are carried out sequentially: reduction of the initial slabs (see Fig. 1) to reduce their initial width A 1.25-3.0 times to obtain an intermediate width B (see Fig. 2); cutting reduced slabs to. size B; swept weft heating, turning; rolling in the broadening stand to the required width of the sheet D (see Fig. 3) and further rolling in the longitudinal or transverse direction relative to the original slabs until the finished product is obtained in width D and length D (see Fig. 4).

Описываемый способ обеспечивает получение листов всей пеобходимой пшрпны, а также повышеппе механических свойств толстолистовой продукции вследствие увеличени  суммарной степенп деформации по сравнению с прокаткой известными способами.The described method provides for obtaining sheets of all the necessary quantities, as well as improving the mechanical properties of plate products due to an increase in the total degree of deformation compared to rolling by known methods.
