Description
Основными сплавами, примен емыми дл посто нных магнитов з издели х, требующих сочетани высоких остаточной индукции (Вг) и коэрцитивной силы (Не), вл ютс железоникельалюмикиевые сплавы и их производные с добавками кобальта, меди и других элементов.The main alloys used for permanent magnets for products requiring a combination of high residual induction (Br) and coercive force (He) are iron-nickel-aluminum alloys and their derivatives with additions of cobalt, copper and other elements.
Наибольшей магнитной энергией обладают Сплавы типа магннко, содержащие 22-25% кобальта, 12-15% никел , 6,5-9,5% алюмини , 3-4% меди и остальное железо.Magnetic Magnetic Alloys have the highest magnetic energy, containing 22–25% cobalt, 12–15% nickel, 6.5–9.5% aluminum, 3–4% copper, and the rest iron.
Известно, что магнитные свойства посто нных магнитов завис т не только от химического состава и тер-мической обработки, но и от структуры сплава и увеличение магнитной энергии от данного объема магнита обеспечиваетс созданием направленной кристаллизации.It is known that the magnetic properties of permanent magnets depend not only on the chemical composition and thermal treatment, but also on the structure of the alloy and the increase in magnetic energy on a given magnet volume is provided by the creation of directional solidification.
В основу предлагаемого способа изготовлени посто нных л ап1Итов с направленной кристаллизацией положен известный способ получени последней путем заливки формы сплавом, нагрева формы и охлаждени плоскости полюса магнита.The basis of the proposed method for the production of fixed lithiums with directional solidification is a known method of obtaining the latter by pouring a mold with an alloy, heating the mold and cooling the plane of the magnet pole.
Особенностью предлагаемого способа вл етс объемный нагрев указанной формы, выполненной из керамических блоков в печи при температуре 1380-1400°.A feature of the proposed method is volumetric heating of a specified form, made of ceramic blocks in a furnace at a temperature of 1380-1400 °.
На фиг. 1 и 2 в продольном и поперечном разрезах показана печь дл осуществлени указанного объемного нагрева формы с последующим резким охлаждением в заданном направлении.FIG. Figures 1 and 2 show, in longitudinal and transverse sections, a furnace for carrying out said volumetric heating of the mold, followed by quenching in a given direction.
Нечь имеет рабочую камеру /, выложенную огнеупорным кирпичом 2 и изолированную листовым асбестом 3 и теплоизол ционным материалом 4. Карборундовые нагреватели 5, создающ1 е температуру 1400°, расположены вдоль боковых стенок рабочей камеры.Nech has a working chamber /, lined with refractory brick 2 and insulated with sheet asbestos 3 and insulating material 4. Carborundum heaters 5, creating a temperature of 1400 °, are located along the side walls of the working chamber.
Дл надежного электрического контакта между токопоиводами и карборундовыми нагревател ми 5 -последние одним концом упираютс в стаканчики 6, закрепленные на асбоцементной плите 7. С противоположной стороны они поджимаютс болтами 5. В своде печи имеютс окно 9 дл контрол температуры нагрева и заливки формы жидким сплавом и окно 10 дл холодильника // с гибкими шлангами, For reliable electrical contact between the current collectors and the carborundum heaters 5 - last one end of the abutment cups 6, mounted on the asbestos-cement slab 7. On the opposite side they are pressed by bolts 5. In the arch of the furnace there are a window 9 to control the temperature of heating and pouring the form with a liquid alloy and window 10 for a refrigerator // with flexible hoses,
