Continuous high temperature brazing furnace is a continuous heat treatment production line. It is mainly used to control the forming of powder metallurgy products. The ideal continuous brazing process is carried out under controlled atmosphere. The production line is characterized by advanced control, remarkable energy saving, easy maintenance and quality assurance. Continuous high temperature brazing furnace heating furnace cuboid, with steel, plate welded together, made of stainless steel long furnace put in furnace, heating elements in the furnace upper and lower sides, between the furnace and the furnace shell filled with insulation material, water-cooled layer structure, the inner layer with stainless steel welded together, coat with 4 mma3 iron sink, sink three sections of each paragraph in 2 inch pipe connection, under the action of high pressure water pump to circulating water cooling; The heating furnace body is connected with the water cooling jacket, and the mesh belt is worn in the furnace tank. Driven by the rotating mechanism, the mesh belt feeding port runs to the water cooling jacket feeding port.
