Description
1,one,
Изобретение относитс к способа термической обработки листов магнитопроводов в контроли1руемой атмосфере, которые .примен ютс , например, в электротехнической промышлениости .The invention relates to a method of heat treatment of sheets of magnetic conductors in a controlled atmosphere, which are used, for example, in the electrical industry.
Известен способ тер мичесКой обрНботки Листов магнитопроводоВ, включающий обжиг масла, оксидацию иа воздухе в вод ных пан рах в восстановительной атмосфере при температуре от 600 до 1300°С, «изкотемпературный отжиг при 750-950°С.The known method of thermal processing of magnetic conductor sheets, including oil burning, oxidation and air in water panels in a reducing atmosphere at a temperature of 600 to 1300 ° C, “is annealing at 750–950 ° C.
Дл иитенсификации процесса термической обработки предложен способ, по -которому операции обжига масла: и оксидации поверхности листов провод т перед отжигом совместно прН температуре оксидации.In order to imitate the heat treatment process, a method has been proposed in which the oil burning operation: and the oxidation of the surface of the sheets are carried out before the annealing together at the oxidation temperature.
Способ заклю.чаетс в следующем.The method is as follows.
Обжиг масла и оксидацию поверхности листов в воздушной или (Паро-воздушной атмосфере провод т при 600-650°С в течениеThe burning of oil and the oxidation of the surface of the sheets in an air or (vapor-air atmosphere is carried out at 600-650 ° C for
22
30-50 мин, отжиг при температуре 850- 870°С в течение 1,5-2 час в контролируемой атмосфере, охлаждение до температуры 600-650°С со скоростью не более 100°С в 1 час.30-50 min, annealing at a temperature of 850-870 ° C for 1.5-2 hours in a controlled atmosphere, cooling to a temperature of 600-650 ° C at a rate of not more than 100 ° C in 1 hour.
Совмещение операций обжига масла и оксидации поверхности листов магнитопроводов сокращает длительный процесс и удещевл ет его.The combination of oil firing and surface oxidation of the sheets of magnetic cores reduces the long process and makes it cheaper.
Предмет изобретенийSubject of inventions
Способ термической обработки листов МаГНитопроводов , включающий обжиг Масла, отжиг при температуре 750-950°С в контролируемой атмосфере и оксидацию при 600- 650°С в паровой и воздушной атмосфере, orличающийс тем, что, с целью интенсификации процесса, операции обжига масла и оксидации поверхности листов провод т перед отжигом совместно ирн температуре оксидации.The method of heat treatment of sheets of magnet piping, including burning oils, annealing at a temperature of 750-950 ° C in a controlled atmosphere and oxidation at 600-650 ° C in a steam and air atmosphere, or because, in order to intensify the process, the operation of burning oil and oxidation the surfaces of the sheets are carried out before annealing together, at the oxidation temperature.
