AI Technical Summary
In existing atmosphere sintering furnaces, the atmosphere does not make sufficient contact with the sample surface, resulting in low atmosphere utilization, increased operating costs, and poor performance.
The atmosphere's effective range is adjusted by employing internal and external gas barrier structures, and comprehensive contact between the atmosphere and the sample is achieved through a linkage structure. The atmosphere utilization rate is improved by utilizing the jet assembly.
It improves atmosphere utilization, reduces operating costs, and enhances the practicality and applicability of the device.
