Title:
EXTERNALLY HEATED VACUUM CONTINUOUS SINTERING FURNACE
Document Type and Number:
WIPO Patent Application WO/2020/108409
Kind Code:
A1
Abstract:
An externally heated vacuum continuous sintering furnace, comprising a vacuum transition chamber (1), an externally heated sintering chamber (2) and a cooling chamber (3) which sequentially communicate with one another, wherein isolation valves are respectively arranged at two ends of the vacuum transition chamber (1) and two ends of the cooling chamber (3); the vacuum transition chamber (1), the externally heated sintering chamber (2) and the cooling chamber (3) respectively form independent spaces by means of the isolation valves; and the vacuum transition chamber (1), the externally heated sintering chamber (2) and the cooling chamber (3) communicate with vacuum units (8). A multi-stage heating structure is employed in the externally heated sintering chamber (2), a transition chamber conveying mechanism is provided in the vacuum transition chamber (1), a cooling chamber conveying mechanism is provided in the cooling chamber (3), and a material box in the externally heated sintering chamber (2) is transferred to the cooling chamber conveying mechanism by means of the transition chamber conveying mechanism. The present invention inherits all of the advantages of an internally heated multi-chamber vacuum sintering furnace and overcomes the defects of complex structure and high cost. By means of the ingenious connection to a magnetic field press and dry isostatic pressing, the furnace may be changed so as to operated in a sealed system, and the oxygen content may be well controlled.
