Description
Technical Field
The utility model belongs to the technical field of kiln facility, concretely relates to oven structure of push plate furnace.
Background
The push plate furnace is mainly used for sintering (custom called as sintering) of electronic ceramics, special ceramics, alumina and zirconia ceramics, honeycomb ceramics, rare earth, magnetic materials, lithium battery anode materials, chemical powder, tricolor fluorescent powder, crystalline silicon photovoltaic cell materials, alumina substrates, aluminum nitride substrates and the like.
The pusher furnace belongs to a continuous furnace, is suitable for continuous operation for a long time, and is used for placing non-powder and non-granular materials, such as the alumina substrate, the aluminum nitride substrate and the like, on a pusher. Compared with the roller furnace, the driving medium of the push plate furnace is the push plate and the push plate can be made of corundum high-temperature resistant materials, so the long-time use temperature of the push plate furnace can reach more than 1700 ℃, for example, 1730 ℃ (1800 ℃ under oxygen atmosphere), while the roller furnace can use a recrystallized silicon carbide roller rod, but the long-time use temperature of the roller furnace is usually about 1300 ℃. The roller bed furnace can be designed to be infinitely long in theory, so that the roller bed furnace which is in service in China, namely is in use, is not uncommon, but the length of the pusher furnace is reasonably controlled because the pusher furnace advances in a mode of mutual pushing and pushing of the pusher plates. For example, the length of the pusher furnace with medium and low temperature is usually about 30-40m, while the length of the pusher furnace with high temperature is usually about 20m, because once the arch occurs, serious accidents can be caused, but the pusher furnace is not really limited by the foregoing examples.
