Abstract
Изобретение относитс к металлургии и может примен тьс при производстве металлических полос, преимущественно изотропной электротехнической стали. Цель изобретени - улучшение магнитных свойств стали, уменьшение разнотолщинности полосы и повышение надежности способа. Способ включает гор чую прокатку слитков на сл бы, нагрев и гор чую прокатку сл бов на подкат с использованием прокатки с неравными окружными скорост ми валков, холодную прокатку в одну или две стадии с промежуточным отжигом, заключительный отжиг, отличающийс тем, что по меньшей мере в одной клети гор чую прокатку сл бов на подкат ведут с использованием приводного валка диаметром D1 и неприводного валка диаметром D2, причем D2/D1 = 1,002...1,2. Кроме того, по меньшей мере в одной клети одну и ту же сторону полосы деформируют приводным валком и по меньшей мере в одной клети деформируют неприводным валком. 1 з.п.ф-лы, 1 табл.The invention relates to metallurgy and can be used in the production of metal strips, mainly isotropic electrical steel. The purpose of the invention is to improve the magnetic properties of the steel, reduce the strip thickness variation and increase the reliability of the method. The method includes hot rolling of ingots into slabs, heating and hot rolling of rolling slabs using rolling with unequal peripheral roll speeds, cold rolling in one or two stages with intermediate annealing, final annealing, characterized in that at least In one stand, hot rolling of slabs to the tackle is carried out using a drive roll with a diameter D 1 and a non-drive roll with a diameter D 2 , and D 2 / D 1 = 1.002 ... 1.2. In addition, in at least one stand, the same side of the strip is deformed with a drive roller and in at least one stand is deformed with a non-drive roller. 1 hp ff, 1 tab.
Description
Изобретение относитс к металлургии и может примен тьс при производстве металлических полос преимущественно изотропной (динамной) электротехнической стали.The invention relates to metallurgy and can be used in the production of metal strips of predominantly isotropic (dynamo) electrical steel.
Цель изобретени - улучшение магнитных свойств стали, уменьшение раз- нотолщинности полосы и повышение надежности способа.The purpose of the invention is to improve the magnetic properties of the steel, reduce the strip thickness and increase the reliability of the method.
Пример После прокатки слитка на сл б и его нагрева до 1350°С провели гор чую прокатку сл ба на подкат толщиной 2,3 мм с применением в чистовой прокатке предлагаемого способа. Прокатку с одним неприводным валком вели в двух последних клет х (кл. 10Example After rolling an ingot on a slab and heating it to 1350 ° С, a hot rolling of a slab on a tackle with a thickness of 2.3 mm was carried out using finishing method of the proposed method. Rolling with one non-driving roll was conducted in the last two cages x (Cl. 10
и 12) чистовой группы стана 1700 ЛПЦ-2 Кар МК.and 12) the finishing group of the mill 1700 LPC-2 Kar MK.
С целью сравнени р д образцов обработали, выполн прокатку по известному способу и в неоптимальном режиме предлагаемого способа.In order to compare a number of samples processed, performed rolling by a known method and in a suboptimal mode of the proposed method.
Далее вели холодную прокатку подката до конечной толщины 0,5 мм (в толщине 0,53 отжиг при в защитной атмосфере) и заключительный отжиг при 8004.Then, cold rolling was carried out to a final thickness of 0.5 mm (in a thickness of 0.53 annealing under a protective atmosphere) and final annealing at 8004.
Подкат, полученный по известному способу, имел разнотолщиность до 0,09 мм, а полученный предлагаемым способом - ниже 0,05 мм.Tackle, obtained by a known method, had thickness variation up to 0.09 mm, and obtained by the proposed method - below 0.05 mm.
