Description
При применении известных способов термической обработки изделий- , изготовленных «з углеграфитовых материалов (электродов, жаропрочных изделий, нагревателей, электрощеток, угольных разр дников и т. д.), заключающихс в обжиге их до температуры 1300° и графитации при температуре 2500-3000°, с изменением температуры свойства и структура этих материалов мен ютс равномерно по всему объему обрабатываемого издели . Между тем -в р де случаев требуетс , чтобы издели из углеродистых материалов имели неодинаковые физические и полупроводниковые свойства в различных местах сечени . К таким издели м относ тс щетки дл электрических машин, издели р - п-переходом, а также конструкционные детали дл химической промышленности.When using the known methods of heat treatment of products made of carbon graphite materials (electrodes, heat-resistant products, heaters, electric brushes, coal dischargers, etc.), which consist of burning them to a temperature of 1300 ° and graphitization at a temperature of 2500-3000 , with a change in temperature, the properties and structure of these materials vary uniformly throughout the entire volume of the workpiece. Meanwhile, in a number of cases it is required that products made of carbonaceous materials have different physical and semiconductor properties in different places of the cross section. Such products include brushes for electrical machines, products by the p-junction, as well as structural parts for the chemical industry.
Дл получени изделий из углеродистого материала с неодинаковыМИ свойствами в разных местах сече«и предлагаетс дл их термообработки примен ть индукционный нагрев токами высокой частоты.To obtain products from carbonaceous material with different properties in different parts of the section, it is proposed to apply heat-induced induction heating for their heat treatment.
При изготовлении двух- и трехслойных щеток прессованные заготовки после обжига графитируютс по предлагаемому способу на требуемую глубину по заданному режиму. Дл получени более резких отличий в свойствах разных слоев можно охлаждать издели водой или жидкими газами.In the manufacture of two-and three-layer brushes, the pressed blanks after firing are graphitized according to the proposed method to the required depth in a given mode. To obtain sharper differences in the properties of different layers, it is possible to cool the product with water or liquid gases.
Применение предлагаемого способа к издели м с р - п-переходом из углеграфито-вых материалов позвол ет совместить термообработку одного и того же издели при двух температурах: внутреннего сло при температуре 2000-2300° и внешнего -при 2900-3100°. При обработке при температуре 2000-2300° материал приобретает дырочную проводимость, а материал, обработанный, при 2900-3100°, имеет -электронную проводимость.The application of the proposed method to products with a p-n junction of carbon-graphite materials allows one to combine heat treatment of the same product at two temperatures: the inner layer at a temperature of 2000-2300 ° and the outer one at 2900-3100 °. When processing at a temperature of 2000-2300 °, the material acquires a hole conductivity, and the material treated, at 2900-3100 °, has an electronic conductivity.
о 132308- 2 Предмет изобретени o 132308- 2 Subject of the invention
Применение и«дукционного нагрева токами высокой частоты дл термообработки изделий -из углеродистых материалов, с целью придани им различных физических и полупроводниковых свойств в разных местах сечени .The use of duction heating by high-frequency currents for the heat treatment of products made of carbonaceous materials, in order to impart to them various physical and semiconductor properties in different places of the cross section.
