Description

Р1зобретение относитс  к обработке посто нных магнитов.The invention relates to the processing of permanent magnets.

Известен способ термомагнитной обработки посто нных магнитов, включающий нагрев и охлаждение в магнитном поле.The known method of thermomagnetic treatment of permanent magnets, including heating and cooling in a magnetic field.

Однако известный способ не позвол ет точно регулировать скорость охлаждени  в процессе обработки.However, the known method does not allow precise control of the cooling rate during processing.

Цель изобретени  - улучшение качества и снижение себестоимости изготовлени  магнитов .The purpose of the invention is to improve the quality and reduce the cost of manufacturing magnets.

Предлагаемый способ отличаетс  тем, что магниты охлаждают в подогреваемом теплоотборвике до 500-600° С, затем привод т охлаждение иа воздухе.The proposed method is characterized in that the magnets are cooled in a heated heat sink to 500-600 ° C, then the air is cooled.

Издели  помещают в печъ дл  нагрева под закалку, провод т выдержку и помещают в подогреваемый до заданной температуры теплоотборник . Теплоотборник с асбестовой оболочкой на наружной поверхности помещаетс  между полюсами намагничивающей устанрвки . После того, как температура в системе магнит - Теплоотборник снизитс  до 500-600°С, изделие извлекают и охлаждают на воздухе.The products are placed in a furnace for heating for quenching, holding is held and placed in a heat collector heated to a predetermined temperature. A heat sink with an asbestos sheath on the outer surface is placed between the poles of the magnetizing installation. After the temperature in the magnet-heat collector system is reduced to 500-600 ° C, the product is removed and cooled in air.

Оптимальный график охлаждени  получают подбором температуры и массы теплоотборника , при этом график охлаждени  остаетс  посто нным дл  партии изделий.An optimal cooling schedule is obtained by adjusting the temperature and mass of the heat sink, while the cooling schedule remains constant for the batch of products.

Теплоотборник может представл ть собой npect-форму, гнезда которой соответствуют геометрическим размерам обрабатываемых изделий . Дл  уменьшени  тепловых потерь наружную поверхность теплоотборника целесообразно покрывать теплоизол цией.The heat collector may be a npect-shape, the sockets of which correspond to the geometric dimensions of the processed products. In order to reduce heat losses, it is advisable to cover the outer surface of the heat sink with thermal insulation.

Предмет изобретени Subject invention
