Description
Трансформаторные кремнистые листы с содержанием Si выше 3% толщиной 0,05-0,10 мм обычно прокатываютс на станах холодной прокатки, предварительно подотретыми до 100- 200 , с весьма малой производительностью . Гор ча прокатка тончайших профилей кремнистой стали в 16-32 и более листов в пакете обш,еприн ты.ми методами ведет к низкому выходу тодных листов вследствие сварки или слипани , а также порезам листов.Transformer silicon sheets with a Si content above 3% with a thickness of 0.05-0.10 mm are usually rolled on cold rolling mills that have been previously sub-cut to 100-200, with a very low productivity. Hot rolling of the thinnest profiles of silicon steel in 16-32 and more sheets in a package, using methods, leads to a low yield of sheet sheets due to welding or sticking, as well as to cut sheets.
Изобретением предлагаетс способ прокатки тонких кремнистых листов пакетами, исключающий сварку (слипание ) и порезы листов и обеспечивающий высокую производительность и выход годного материала.The invention proposes a method of rolling thin silicon sheets in packages, eliminating welding (sticking) and cuts of sheets and providing high performance and yield of suitable material.
Способ заключаетс в ТОМ, что пакет листов перед прокаткой закладываетс в металлическую покрыщку, подогретую до температуры 650-800°, после чего Покрышка вместе с листами подвергаетс прокату. Листы нагреваютс и приобретают необходимую дл прокатки пластичность за счет тепла покрышки. Вместо закладывани пакета листов в подогретую покрышку можно вкладывать в пакет листов подогретый металлический лист.The method consists in the fact that the package of sheets before rolling is laid in a metal sheet heated to a temperature of 650-800 °, after which the tire together with the sheets is rolled. The sheets are heated and acquire the plasticity necessary for rolling due to the heat of the tire. Instead of laying the package of sheets into a heated tire, you can put a heated metal sheet into the sheet package.
