мешена подвижна  вопокниста  угперодсодержаща  лента 12,которую перемещают валки 13 и 14. Туннельна  камера 7 окружена сажевой волокнистой теплоизол цией 15 и корпусом 16. Газовые затворы 17 и 18 предназначены дл  подачи инертного газа в туннельную камеру 7. Устройство работает cлeдyющи r образом Графитовый нагреватель 3 довод т до заданной температуры (2400-28ОО С) при непрерывной работе газовых затворов 17 и 18„ После вывода печи в равновесный тепловой режим привод т в движение транспортерную 8 и углеродсодержашую ленту 12с помощью валков 10, 11 и 13, 14. По мере перемещени  обрабатываемых изделий 9 вдоль туннельной камеры 7 выдел ющиес  из изделий зольные примеси осаждаютс  на движущуюс  волокнистую углеродсодержашую ленту 12 и вынос тс  из туннельной камеры 7. Скорость перемещени  транспортерной ле лы 8 определ етс  заданным графиком подъе ма температуры и требуемой изотермической выдержкой при конечной температуре дл  ко кретного вида обрабатываемых изделий 9; скорость перемещени  волокнистой углеродсо держащей ленты 12 предопредел етс  скоростью осаждени  на ней зольных примесей и минимальной величиной допустимого технологического зазора между издели ми 9, лентой 12 и соответствующей поверхностью туннельной камеры 7, Эффект экранировани  усиливаетс  в предлагаемой печи вследствие того, что удельна  поверхность волокнистой углеродсодержашей пенты 12 на пор док превышает удельную поверхность компактных углеграфитовых переходников 2 и 4 и нагревател  3 туннельной камеры 7. В тех случа х, когда осаждение на поверхность обрабатываемого материала 9 зольных примесей  вл етс  нежелательным, направление перемещени  волокнистой углеродсодержащей ленты 12 выбираетс  противоположным направлению перемещени  транспортерной ленты 8. Формула изобретени  Конвейерна  печь дл  термообработки углеродистых материалов и изделий по авт. свид. № 499485, отличающа с  тем, что, с целью повыщени  эффективности работы за счет снижени  зарастани  зольными примес ми туннельной камеры, последн   снабжена дополнительной волокнистой углеродсодержащей лентой, размещенной с возможностью продольного перемещени  между обрабатываемыми издели ми и стенками камеры.An agitated perforated tape 12, which rolls 13 and 14 move. The tunnel chamber 7 is surrounded by carbon black thermal insulation 15 and the housing 16. Gas closures 17 and 18 are designed to supply inert gas to the tunnel chamber 7. The device works in the following way Graphite heater 3 brought to a predetermined temperature (2400-28OO C) with continuous operation of gas gates 17 and 18 After the furnace is brought to equilibrium thermal mode, the conveyor 8 and carbon-containing tape 12 are moved with the help of rolls 10, 11 and 13, 14. As the processed products 9 move along the tunnel chamber 7, the ash impurities released from the products are deposited on the moving carbon fiber tape 12 and removed from the tunnel chamber 7. The speed of movement of the conveyor layer 8 is determined by a predetermined temperature rise curve and the required isothermal exposure at temperature for a specific type of processed products 9; The speed of the carbon fiber with the holding tape 12 is predetermined by the deposition rate of ash impurities and the minimum allowable technological gap between the products 9, the tape 12 and the corresponding surface of the tunnel chamber 7. The shielding effect is enhanced in the proposed furnace due to the specific surface of the carbon fiber containing pen 12 an order of magnitude greater than the specific surface area of the compact carbon-graphite adapters 2 and 4 and the heater 3 of the tunnel chamber 7. In those cases and depositing on the treated surface material 9 ash impurities is undesirable, the direction of movement of the fibrous carbonaceous belt 12 is selected opposite to the direction of movement of the conveyor belt 8. The conveyor oven Formula invention for heat treatment of carbon materials and products according to the authors. swith No. 499485, characterized in that, in order to increase work efficiency by reducing the overgrowth of ash tunnel contaminants with ash, the latter is provided with an additional carbon fiber tape that is placed with the possibility of longitudinal movement between the workpiece and the walls of the chamber. . 1. one
