Description
Изобретение относиж к изготовлению изделий из nopoiuiKOiB огнеупорных материалов и металлов методом гор чего прессовани .The invention relates to the manufacture of products from nopoiuiKOiB refractory materials and metals by the method of hot pressing.
В на1сто щее врем известны пресс-формы дл гор чего прессовани при температурах выше 800-900°С, в Которых формообразующие элементы (матрицы и пуансоны) выполнены из окиси берилли , окиси цир.кони , циркоаа, окист алюмини , нитрида алюмини .Molds for hot pressing at temperatures above 800–900 ° C, in which the shaping elements (dies and punches) are made of beryllium oxide, zirconium oxide, zircoa, aluminum oxide, aluminum nitride, are currently known.
Цель изобретени - повышение механической прочности праос-формы.The purpose of the invention is to increase the mechanical strength of the Praos form.
Это достигаетс тем, что матрица и пуансоны выпойнены из поллкристаллического самосв занноро карбида кремни .This is achieved by the fact that the matrix and punches are lined from self-crystallized silicon carbide polycrystalline.
На чертеже схемаши ческв изображена предлагаема преос-фОрма.The schematic drawing of cheskos depicts the proposed preos-form.
В корпусе / у|К|реплен индуктор 2, в центре которого установлена матрица 3, пуансоны 4 и 5. Формообразующие элементы изготовлены .из поли,крИ1СтаЛЛичеакого самосв занного карбида кремни .In the casing / y | K | replen inductor 2, in the center of which is installed the matrix 3, punches 4 and 5. Forming elements are made of poly, crI1StaLLic self-bonded silicon carbide.
Издели прессуют в предлагаемой прессформе по обычному ЦИКЛу.The products are pressed in the proposed mold in a conventional CYCLE.
Формообразующие элементы подвергают индукционному нагреву токами высокой частоты (2500 гц) машинного гене|ратора мощностью 100 кет. При. потребл емой мощности 70-80 кет и со8ф 0,95-0,98, така форма нагреваетс до 1600°С. В ореос-форме прн применении таких формообразующих элементов были спрессованы при. температуре 1400°С и давление авыще 150 кг/см иадели диаметром 80 мл1.Forming elements are subjected to induction heating by high-frequency currents (2500 Hz) of a machine generator with a capacity of 100 kW. At. power consumption is 70-80 kW and co8f 0.95-0.98, this form is heated to 1600 ° C. In oreos-form prn the use of such formative elements were pressed at. temperature is 1400 ° C and the pressure is as high as 150 kg / cm and the saddle has a diameter of 80 ml1.
Описываема пресс-форма дл гор чего прессова1ни цри температуре выще 800- 900°С может быть использована дл Щ|прокого промыщленното внедрени .The described mold for a hot press at a temperature higher than 800 to 900 ° C can be used for Schu |
Предмет изобретени Subject invention
Лреос-фо.рма дл гор чего прессовани , включающа индуктор., .матрицу и пуа соны, отличающа с тем, что, с целью многократного использовани пресс-формы и повышени ее механической прочности при высоких те.мпературах, матрица и пуансоны выполнены из поликристалличеакого: самосв занного карбида Кремни .Lreos-foorma for hot pressing, which includes an inductor, a matrix and pulses, characterized in that, in order to reuse the mold and increase its mechanical strength at high temperatures, the matrix and punches are made of polycrystalline : self-bonded silicon carbide.
