The invention discloses a high-temperature
hydrogen furnace for
sintering a
ceramic tube. The high-temperature
hydrogen furnace comprises a supporting table, a boat and a
corundum box, wherein the upper end of the supporting table is provided with a
sintering furnace, the two ends of the
sintering furnace are provided with a feeding hole and a connecting zone respectively, the feeding hole is connected to one end of the sintering furnace and communicates with the inside of the sintering furnace, and one end, far away from the feeding hole, of the sintering furnace is connected with the connecting zone; the sintering furnace is divided into five zones, the sintering furnace comprises a high-temperature zone and a
buffer zone, the
buffer zone is connected with the connecting zone, the high-temperature zone is arranged in the middle of the sintering furnace, a cooling zone is connected to the end, away from the sintering furnace, of the connecting zone, a guide rail is arranged on the supporting table, the guide rail penetrates through the sintering furnace, the cooling zone and a
discharge hole, and a push
handle is movably arranged on the surface of the guide rail. According to thehigh-temperature
hydrogen furnace, a condensation water connecting
pipe which is used for inputting water circularly is arranged, so that the condensate water can be circularly processed; and the guide rail which penetrates through the whole process can automatically move the
ceramic tube, so that less manual participation is achieved.
