Description
таллическим листом, затем на него помещают металлические противни или решетки, на которое };кладывают в несколько слоев металлические заготовки из железо-кобальтового сплавдС содержащего 2О-30% кобальта , 0,1-1,1% хрома, остальное железо, например 27КХ, предварительно обезжиренное в органическом р«:творителе. Решетки и противни укладывают, в несколько русов в зависимости от высоты контейнера.a metallic sheet, then metal pans or grates are placed on it} on which metal blanks of iron-cobalt alloy C containing 2O-30% cobalt, 0.1-1.1% chromium, the rest iron, for example, 27KH, are placed in several layers, pre-skimmed in organic p ": Creator. Grates and trays are placed in several Rus depending on the height of the container.
Контейнер с металлическими заготов1(ами. помещают в рредварительно нагретую до « 800 электричесу ую печь (щахтного или муфельного «ипа) и выдерживают в течение 0,4-1,1 ч, после чего охлаждают со скоростью 1ОО-150 с/ч до ЗОО°С, а затем сThe container with metal blanks1 (amy. Is placed in an electrically heated furnace (800 or muffle “ip)” preliminarily heated to “800” and kept for 0.4–1.1 h, then cooled at a rate of 1OO-150 s / h to ZOO ° C and then with
произвольной скоростью, с целью уменьшени содержани кислорода в атмосфере контейнера окисление деталей производ т в присутсрВИИ мелко раздробленного антрацита (4-20 об%), св зывающего -избыточное количество кислорода и создающего защитную атмосферу состава % 80,7-78 Нз ; 8,75-3;2 Оу ; 0,8-1,6 СО ; 6,8-14,1 СО- ; 1,55-1,0 Лг 0,6-1,6 0,5-0,3 СНд .arbitrary speed, in order to reduce the oxygen content in the container atmosphere, parts are oxidized in the presence of finely divided anthracite (4–20%), binding — excess oxygen and creating a protective atmosphere of% 80.7-78 Nz; 8.75-3; 2 Oy; 0.8-1.6 SD; 6.8-14.1 SO-; 1.55-1.0 Lg 0.6-1.6 0.5-0.3 SND.
Металл, обработанный по предлагаемому способу, обладает высокими магнитными свойствами (значени и выще норм по ГОСТ 10160-75) и высокой пластичностью (см. таблицу. Кроме того, способ позвол ет исключить предварительный отжиг деталей, совместив его с оксидированием, тем самым значительно снизить трудоемкость.The metal processed by the proposed method has high magnetic properties (value and higher than the norms according to GOST 10160-75) and high plasticity (see table. In addition, the method eliminates the preliminary annealing of parts, combining it with oxidation, thereby significantly reducing labor intensity.
