Description

В основном авт. св. К 73931 описан снособ изготовлени  посто нных магнитов, причем дл  улучшени  магнитных свойств, опоку с залитьЕм в нее сплавом помещают в магнитное поле сразу после заливки в нее сплава, когда последний находитс  ен1е в жидком состо нии.Basically auth. St. To 73931, a method of manufacturing permanent magnets has been described, and to improve the magnetic properties, the casting box with the alloy in it is placed in the magnetic field immediately after the alloy is cast in it, when the latter is in the liquid state.

Неудобство этого способа заключаетс  в том, что дл  его осуществлени  необходимо изготовл ть специальные опоки из немагнитного материала, снабженные магнитными иаконечниками.The disadvantage of this method is that in order to carry it out it is necessary to make special flasks of non-magnetic material, equipped with magnetic tips.

Предлагаемый способ предусматривает на.магничивамие сплава в гор чем состо нии вне опоки. Сплав заливаетс  в опоку обычным путем и затем отливка быстро выбиваетс  из опоки и помещаетс  между полюсными наконечниками электромагнита. До момента помеидени  отливки в магнитное поле она успевает затвердеть только с поверхности, внутренние же части отливки наход тс  еще в расплавленном состо нии . Дл  получени  хорощих магнитных свойств необходимо, чтобы отливка иoмeпJ,aлacь в магнитное поле при температуре не ниже 900.The proposed method provides for the magnetism of the alloy in a hot state outside the flask. The alloy is poured into the flask in the usual way and then the casting is quickly knocked out of the flask and placed between the pole pieces of the electromagnet. Until the moment of pomideni casting in a magnetic field, it manages to harden only from the surface, while the internal parts of the casting are still in the molten state. In order to obtain good magnetic properties, it is necessary that the casting of a metal is in a magnetic field at a temperature not lower than 900.

Другим преимуществом предлагаемого способа  вл етс  возможность регулировани  скорости охлаждени  отливки и выбора оптимального времени охлаждени  сплава, при которых магнитные CBoiicTBa готового изде.ш  будут наилучщими. Дл  этого от/ишка обдуваетс  воздухом 1ли наоборот, утепл етс  асбестом или другим подход щи.м материалом . Во врем  остывани  отливка все вpe.  находитс  в магнитном поле.Another advantage of the proposed method is the ability to control the cooling rate of the casting and to select the optimal cooling time for the alloy at which the magnetic CBoiicTBa of the finished product will be the best. For this, air is always blown from the hood to the contrary, insulated with asbestos or other suitable material. During the cooling of the casting all the time. is in a magnetic field.
