Description
(54) ПРОХОДНАЯ МУФЕЛЬНАЯ ПЕЧЬ С КОНТРОЛИРУЕМОЙ(54) PASSAGE MUFFEL OVEN WITH CONTROLLED
АТМОСФЕРОЙATMOSPHERE
II
Изобретение относитс к термическб му оборудованию с контролируемой атмосферой , преимущественно к печам дл термообработки изце1шй электронной и радиотехническсЛ промыииюнности.The invention relates to thermal equipment with a controlled atmosphere, mainly to furnaces for the heat treatment of metal and radio electronic equipment.
Известна муфельна печь с контролируемой атмосферой, имеюща нагревательную камеру с герметичным металлическим муфелем.на концах которого расположены гвэовые затворы, преп тствующие попаданию воздуха в муфель гфи работе печи. Подача контролируемой атмосферы в муфель осуществл етс через трубопрсюоды, вставл емые внутри муфел с его торцов на незначитет ную длину 1.A controlled atmosphere muffle furnace is known, having a heating chamber with a hermetic metal muffle. At its ends there are guards valves preventing the ingress of air into the muffle of the furnace. The controlled atmosphere is fed into the muffle through pipe fittings inserted inside the muffle from its ends to an insignificant length 1.
Недостатком известней печи вл етс то, что газ подаетс в начальную и ную зоны муфел , а не в зону максимальной температуры, а это снижает качество термообработки изделий.The disadvantage of the furnace is that the gas is supplied to the initial and the nozzle zones of the muffle, and not to the zone of maximum temperature, and this reduces the quality of the heat treatment of the products.
Наиболее близким по технической сущности к предлагаемой вл етс проходна муфельна печь, содержаща рабочую камеру с металлическим муфелем и наг евател ми , образующими температурные зшы, систему ввода технологического газа в муфель, выполненную в виое распределительного коллектора с газсжыпускными отверсти ми. Распределительный коллектор расположен над муфелем между доками пресеварительного нагрева и спекани обрабатываемого материала 2.The closest to the technical essence of the present invention is a passage muffle furnace, containing a working chamber with a metal muffle and heaters, forming temperature shy, a system for introducing process gas into the muffle, made in the distribution manifold with gas outlet openings. Distribution manifold is located above the muffle between the docks of preheating heating and sintering of the processed material 2.
Однако эта печь также не обеспечивает равномерную подачу технологическо10 го газа по всей длине муфел и непосредственно в зону высокой температуры, что снижает качество обрабатываемых изаелнй .However, this furnace also does not provide a uniform supply of process gas over the entire length of the muffle and directly into the high temperature zone, which reduces the quality of the treated materials.
Цель изобретени - повышение качест The purpose of the invention is to improve the quality
IS ва термообработки изоелий за счет равномерного распределени технологического газа по всей длине муфел .IS va heat treatment of isoelia due to uniform distribution of the process gas along the entire length of the muffle.
