Technical Field

[0001] The utility model belongs to the technical field of hard alloy production, and in particular relates to a hard alloy sintering and dewaxing device. Background Art

[0002] As a metal that combines high strength, hardness, corrosion resistance, and high temperature resistance, the production process of cemented carbide involves a dewaxing and pre-burning stage (600-800°C); a solid-phase sintering stage (800°C eutectic temperature - 1340°C); a liquid-phase sintering stage (eutectic temperature - sintering temperature - 1400°C); and a cooling stage (sintering temperature - room temperature). In the production process of cemented carbide, cemented carbide needs to go through two processes: removing the wax from the surface and sintering. Usually, intermittent dewaxing and sintering are used, which has low production efficiency. In addition, during the dewaxing and sintering process of cemented carbide, cemented carbide is often heated statically, resulting in uneven heating of the cemented carbide, which affects the quality of the dewaxing and sintering processes. In addition, in the dewaxing process, the cooled wax liquid can easily clog the holes in the filter plate used for dewaxing. The existing filter plate is inside the dewaxing furnace, which makes it difficult to disassemble the filter plate.

[0003] Therefore, a cemented carbide sintering and dewaxing device is needed to solve the problems in the prior art of uneven static heating effect of cemented carbide blocks and easy clogging of filter plates by debris produced by dewaxing. Utility Model Content
