Description

11зобретение относитс  к способам нолучени  магнитотзердых сплавов системы железопикель-алюминнй-кобальт-медь-тнтан , наход щих широкое применение в радиотехнической, приборостроительной и других отрасл х промышленности .11, the invention relates to the methods of obtaining magnetically graded alloys of the iron nickel-aluminium-cobalt-copper-tntane system, which are widely used in the radio engineering, instrument-making and other industries.

Посто нные магниты на этих сплавов ввиду высокого сродства комнопентов к -кислороду имеют большое количество неметаллических включений и окислов, что приводит к их повышенной хрупкости, ухудшению обрабатываемости , снижению магнитных .характерисТИ )Л.Due to their high affinity for α-oxygen, permanent magnets on these alloys have a large number of nonmetallic inclusions and oxides, which leads to their increased brittleness, deterioration of workability, reduction of magnetic characteristics.

Целью изобретени   вл етс  повышение прочностных и магнитиых свойств Л улучшение обрабатываемости сплава.The aim of the invention is to increase the strength and magnetic properties of L and improve the machinability of the alloy.

Дл  этого предложено перед введе;п ем добавок расплав раскисл ть серой, вводимой в виде сульфида железа.To this end, it has been proposed to introduce the additive mixture in the form of sulfur melted sulphide in the form of additives.

Предложенный способ опробован при выплавке сплава ЮНДК35Т5БА.The proposed method was tested in the smelting alloy UNDK35T5BA.

Сплав был выплавлен в индукционной печн ЛПЗ-67 с кварцитовым тиглем под шлаком из стбкла. FeS2 вводили в виде колчедана в два приема: Fe-Со-Ni-Си--/9ре52-The alloy was melted in the LPZ-67 induction furnace with a quartzite crucible under the slag from the steel cell. FeS2 was introduced in the form of pyrites in two steps: Fe-Co-Ni-Cu - / 9re52-
