Description
Предлагаемый способ обжига углеграфитокерамических заготовок с повышенным содержанием св зки отличаетс от известных тем, что издели либо недопустимо деформируютс , либо деформируютс и спекаютс друг с другом или с окружающим пересыпочным материалом, предохран ющим изделие от окислени .The proposed method of burning carbon-ceramic preforms with a high content of binder differs from the known ones in that the products are either unacceptably deformed or deformed and sintered with each other or with the surrounding transfer material that prevents the product from oxidation.
Применение такого способа позвол ет улучшить качество изделий. Способ заключаетс в том, что, с целью устранени деформации и трещиноватости заготовок (труб или блоков), примен етс раздельный обжиг изделий в виде стали.The use of this method allows to improve the quality of products. The method consists in the fact that, in order to eliminate the deformation and fracturing of the blanks (pipes or blocks), separate firing of products in the form of steel is used.
Перва стади обжига (до 400°) протекает в услови х минимального насыщени смол ными парами пространства, окружающего обжигаемое изделие, и создани повышенных конвекционных газовых потоков с примесью окислительных реагентов (воздух, кислород, хлор и т. д.).The first stage of roasting (up to 400 °) proceeds under conditions of minimal saturation with resinous vapors of the space surrounding the product being calcined and creating elevated convection gas flows with admixture of oxidizing agents (air, oxygen, chlorine, etc.).
Втора стади обжига от 400° до 1000° ведетс в услови х насыщени смол ными парами указанного пространства при пониженных скорост х конвекционных потоков. Пониженные конвекционные потоки с насыщенными парами св зки обеспечиваютс применением мелкой засыпки и дополнительной загрузкой пека в торцы печи.The second stage of roasting from 400 ° to 1000 ° is carried out under conditions of saturation with the resin pairs of the specified space at lower rates of convection currents. Reduced convection currents with saturated binder vapors are provided by the use of fine backfilling and additional loading of pitch into the furnace ends.
