Description
1one
Изобретение относитс к очистке поверхности металла от загр знений, в частности к технологии подготовки поверхности дета пей типа пластин из пермалло перед отжиом в вакууме.5The invention relates to the cleaning of the metal surface from contamination, in particular, to the technology of preparing the surface of parts such as permallo plates before being wound in vacuum.
Известен способ обезжиривани деталей перед отжигом, включающий термовихревой обжиг при температуре 650-750 0 в течение от 6 мин и более.There is a known method of degreasing parts before annealing, which includes thermal vortexing at a temperature of 650-750 0 for 6 minutes or more.
С целью удалени зольных участкогвШIn order to remove the ash areas
предложен способ, отличающийс от известного тем, что обжиг провод т при температуре 4ОО-46О°С.a method is proposed which differs from the known one in that the calcination is carried out at a temperature of 4OO-46 ° C.
Предложенный способ обезжиривани деталей перед отжигом включает следующие one-15 рации: детали засыпают в сетчатые корзины или конверты и загружают в электричесую печь типа , нагретую до темпера-; уры 4ОО-46О°С.The proposed method of degreasing parts before annealing includes the following one-15 radios: parts are poured into mesh baskets or envelopes and loaded into an electric furnace of the type heated to temperature; ury 4OO-46O ° C.
Укладку деталей производ т таким образом , чтобы кансда деталь свободно омьта- лась со всех сторон воздухом.iParts are laid in such a way that the component can be freely swept from all sides with air.
Врем выдержки при данной температуре 2О-4О мин в зависимости от конструкции электропечи и величины деталей.The exposure time at this temperature is 2O-4O min, depending on the design of the electric furnace and the size of the parts.
Данный способ обеспечивает удаление жировых загр знений и их зольных остатков .This method removes fatty contaminants and their ash residues.
Предмет изобретени Subject invention
Способ обезжиривани деталей перед отжигом, в1Ш1очающий термовихревой обжиг в течение 2О-4О мин, отличающий с тем, что, с целью удалени зольных остатков, обжиг провод т при температуре 4ОО-46ООС.The method of degreasing parts before annealing, which includes thermal eddy calcination for 2 ~ 4 O min., Characterized in that, in order to remove the ash residues, the calcination is carried out at a temperature of 4OO - 46 OС.
