High-temperature hydrogen furnace for sintering ceramic tube

Abstract

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.

Description

technical field [0001] The invention relates to the technical field of hydrogen-burning furnaces, in particular to a high-temperature hydrogen-burning furnace for sintering ceramic tubes. Background technique [0002] Ceramic steel pipes are essentially different from traditional steel pipes, wear-resistant alloy cast steel pipes, cast stone pipes, steel-plastic, steel rubber pipes, etc. The outer layer of ceramic steel pipes is steel pipe, the inner layer is corundum, and the Vickers hardness of the corundum layer is as high as 1100- 1500 (Rockwell hardness is 90-98), which is equivalent to tungsten-cobalt hard gold, and its wear resistance is more than 20 times higher than that of carbon steel pipes. Grinding machine cuts the main grinding wheel of hardened steel. The corundum layer in the ceramic steel pipe can wear off the corundum grinding wheel. The wear resistance of the ceramic steel pipe mainly depends on the corundum layer with a thickness of several millimeters in...

AI Technical Summary

Problems solved by technology

[0003] Ceramic tubes are sintered by high-temperature hydrogen-burning furnaces. However, in the use of traditional hydrogen-burning furnaces, the firing of ceramic tubes requires manual assistance. High-temperature firing and manual operation will increase the risk of labor, and traditional The cooling rate of the ceramic tube is slow during the firing process, which increases the production cost. Therefore, we urgently need to design a high-temperature hydrogen-burning furnace for ceramic tube sintering to solve the above problems
