Molybdenum foil vacuum brazing furnace

  • 7 Jul

Molybdenum foil vacuum brazing furnace is widely used for brazing structural parts that are difficult to be connected by general methods, especially for vacuum brazing of titanium alloy, stainless steel and other metal materials. In the process of welding various structural parts in high temperature vacuum brazing furnace, the deposition of filler metal will cause deformation and cracking of molybdenum plate in furnace. Under normal use, molybdenum plate of high temperature vacuum brazing furnace will appear deformation and cracking failure due to cold and hot shock deformation and metallographic structure change of molybdenum plate itself, and the time is about 5 years.

In the use of high temperature vacuum brazing furnace brazing applied to ternary catalytic converters in the automotive industry metal honeycomb carrier craft process, a large number of application of a large number of volatile nickel-based filler metals, part of the vacuum brazing furnace vacuum unit discharge, otherwise a considerable part of the deposition of adhesive in the furnace and the insulating layer is mainly in the face of high temperature molybdenum screen deposition is obvious. A large number of nickel-based solder deposits lead to deformation, cracking and other failure forms in the furnace liner molybdenum screen of high temperature vacuum brazing furnace, and the failure time is relatively short. Generally, the furnace liner molybdenum screen needs to be replaced in about 1 year.
