The mesh belt continuous brazing furnace is a widely used industrial furnace. It is an automated industrial equipment suitable for brazing large quantities of metal workpieces (stainless steel parts, copper parts, steel parts, aluminum parts). It is particularly suitable for continuous brazing heat treatment of automotive aluminium intercoolers, water tanks, automotive air conditioning condensers, evaporator heater water tanks, aluminium oil coolers, and other similar products.
Equipment structure
The components of the mesh belt continuous brazing furnace are: degreasing furnace → spray system → drying transmission → drying furnace → drying passive, brazing passive → front room → brazing furnace → water cooling (dry cooling) → strong air cooling → brazing furnace transmission.
The mesh belt is made of 316L stainless steel, which is resistant to high temperature (≤750℃) and corrosion by alkaline brazing filler metals. The brazing temperature range is 550℃～630℃, the temperature control accuracy is ±5℃, and the temperature difference in the furnace is ≤±3℃.
Brazing Furnace Operating Principle
The workpiece is conveyed by a stainless steel mesh belt. The workpiece is placed on the belt and enters the preheating section. It is then transported along the belt through the preheating, heating (melting the brazing material), and cooling process. Workpieces exiting the cooling section are protected by pure hydrogen gas within the muffle. The reducing properties of hydrogen ensure a bright surface and prevent oxidation.
Workpiece Welding
Workpiece welding involves heating the workpiece to melt the filler material (brazing filler metal). Capillary action allows the liquid filler metal to fill the gaps between the base metals. After cooling, the weld is achieved.
Manual loading → mesh belt drive → preheating → heating (melting brazing filler metal) → cooling → manual unloading
Application
Mesh belt continuous brazing furnaces are used in the steel and metallurgical industries. They are suitable for batch production of small and medium-sized stainless steel parts (tableware, knives, hardware, etc.), such as bright quenching and tempering of martensitic stainless steel and bright annealing of austenitic stainless steel. They can also be used for brazing and bright heat treatment of other stainless steel, carbon steel, brass, and copper parts in the refrigerator, air conditioner, electronics, and microwave magnetron industries.
