Embodiment Construction
[0020] Such as Figure 1 to Figure 6 As shown, a continuous operation high-temperature vacuum atmosphere firing furnace is mainly composed of a furnace body 2, a vacuum device 4, an air supply device 5 and a heating device 6.
[0021] Such as Figure 1 to Figure 4 and Figure 6 As shown, the furnace body is linear, and the two ends of the furnace body are respectively provided with a feed bin 1 and a discharge bin 3 . Furnace doors 12 and 25 are respectively arranged between the two ends of the furnace body and the inlet and outlet bins. The discharge bin is provided with a discharge bin door 23 to communicate with the outside world; the feed bin is provided with a feed bin door 13 to communicate with the outside world. The furnace body, the feed bin and the discharge bin form three interconnected or closed spaces. The inner furnace bottom of the furnace body is paved with a track 10, on which a heating trolley 14 is arranged, and the product 15 to be processed is installe...

The invention belongs to a continuous-operation high-temperature vacuum atmosphere sintering furnace which is mainly composed of a furnace body, a vacuumizing device, an air supply device and a heating device. A feed bin and a discharge bin are arranged at two ends of the furnace body, furnace doors are respectively arranged between the two ends of the furnace body and the feed bin and the discharge bin, the feed bin and the discharge bin are respectively provided with a feed bin door and a discharge bin door, tracks are paved at the bottom of an inner furnace of the furnace body, a material heating vehicle is arranged on the tracks, the material heating vehicle in the furnace body is propelled by a driving device, two side walls in the furnace body and the top of the inner furnace are constructed by fireproof materials to form a closed thermal insulation casing, a plurality of heating units of the heating device penetrate through a fireproof material layer at the top of the inner furnace to be located in a space in the thermal insulation casing, and a feed vehicle for bearing the material heating vehicle and a push-pull hydraulic cylinder device for pushing and pulling the material heating vehicle are arranged in the feed bin and the discharge bin. The continuous-operation high-temperature vacuum atmosphere sintering furnace has the advantages of being reasonable in structure, high in production efficiency, high in heat utilization rate, low in energy consumption, capable of performing high-temperature vacuum atmosphere sintering production continuously, large in volume, high in yield and good in using effect.
Description
technical field [0001] The invention relates to a continuously operating high-temperature vacuum atmosphere firing furnace, in particular to a high-temperature synthesis or firing kiln under a non-oxidizing atmosphere. Background technique [0002] Nitriding is an important material in the production of high-temperature ceramics. Nitriding synthesis and nitriding firing must be carried out in high-purity nitrogen, and the time for nitriding synthesis or reaction sintering needs to be longer than 30 to 70 hours. In the past, nitrogen The chemical furnaces are produced intermittently. This kind of operation is that the furnace is operated once, and the furnace lining is exposed to the air. It is difficult to guarantee the purity of nitrogen in the furnace (99.99%); the second is that the production efficiency is low; Waste 40% of energy consumption. [0003] In the production of powder metallurgy and magnetic materials, many products need to be fired in vacuum or non-oxidizin...
