Изобретение относитс к технологии изготовлени магнитогроводов электрических MaiuHH и может быть использовано в электротехнической промышленности ,The invention relates to the manufacturing technology of magnetic electric wires MaiuHH and can be used in the electrical industry,
Известен способ изготовлени магнитопроводов электрических махиин, согласно которому на поверхность штампованных пластин нанос т слоР суспензии, содержащий диоксид кремни затем пластины укладывают в пакет и отжигают при 1500°С l .A known method of manufacturing magnetic magnetic cores, according to which a slurry of a suspension containing silicon dioxide is applied to the surface of the pressed plates, the plates are then placed in a bag and annealed at 1500 ° C.
Недостатком известного способа вл етс невысока механическа прочность получаемого соединени , вследствие чего пакет соедин ют заклепками .The disadvantage of the known method is the low mechanical strength of the resulting compound, as a result of which the bag is riveted.
Известен способ изготовлени магнитопроводов электрических машин, состо щий из нанесени на пластины изол ционного клеющего состава, ст гивани пакета, последующего отжига при 800 1300°С и повторного отжига при 600-700 С после механической обработки 2 .A known method of manufacturing magnetic machines of electrical machines consists of applying an insulating adhesive composition to the plates, shrinking the bag, then annealing at 800 1300 ° C and re-annealing at 600-700 C after machining 2.
Данный cnocoe вл етс наиболее близким к изобретению по технической сущности и достигаемому результату. This cnocoe is the closest to the invention in its technical essence and the achieved result.
Недостатком этого способа вл етс невысока механическа прочностьThe disadvantage of this method is low mechanical strength.
соединени отдельных пластин магнитопровода между собой и разрушение клеющего соединени при нагреве выше 700°С.connecting the individual plates of the magnetic circuit between them and the destruction of the adhesive compound when heated above 700 ° C.
По предлагаемому способу с целью повышени механической проч(ости соединени между пластинами и восстано лени магиитны.ч свойств магнитопрово да пластины магнитопровода предварительно никелируют,затем оксидируют, после чего нанос т спиртовую суспензию , содер аи1ую окислы кремни и немагнитные окислы мeтaллoвV)ll группы Периодической системы Д.И. Менделеева , оксидирование пластин провод т н греванием при 500-600°С на воздухе в течение 20-30 мин, окончательный отжиг пластин провод т в вакууме или инертной среде по режиму: нагрев отAccording to the proposed method, in order to increase the mechanical strength (the joints between the plates and the restoration of the magical properties of the magnetic circuit, the magnetic core plates are pre-nickel plated, then oxidized, after which an alcohol suspension is added, containing silicon oxides and non-magnetic metal oxides V) of the Periodic System II DI. Mendeleev, the oxidation of the plates is carried out by heating at 500-600 ° C in air for 20-30 minutes, the final annealing of the plates is carried out in a vacuum or inert medium according to the mode: heating from
20 до 900°С-1000°С со скоростью не бфлее 150 в час,выдержка 900-1100°С в течение 1 час, охлаждение со скоростью 150°С/час.20 to 900 ° С-1000 ° С with a speed of not more than 150 bpm, an exposure of 900-1100 ° С for 1 hour, cooling at a rate of 150 ° С / hour.
Способ изготовлени состоит из следующих операций. Никелирование пластин пермалло провод т обычным электрохимиическим способом дл получени на поверхности пластин пленки металлического никел . Оксидирование пластин провод т нагреванием их в течеThe manufacturing method consists of the following operations. Nickel plating of permallo plates is carried out in the usual electrochemical manner to produce metallic nickel films on the surface of the plates. The oxidation of the plates is carried out by heating them in flow.
