Vertical vacuum brazing furnace

This Vertical Vacuum Brazing Furnace is mainly used for vacuum brazing of blades made of various high-temperature alloys, stainless steel and other materials. The equipment has a vertical, single-chamber structure, horizontal loading, external circulation, molybdenum-lanthanum alloy heating, and fully automatic control. It has a good user interface, making the user's operation and monitoring simpler and more intuitive. This equipment has advanced and reasonable structural design, and its main supporting products and functional components are imported from abroad. It has advanced level and superior performance, and can adapt to long-term, safe, stable and reliable operation and meet the user's requirements.
