Brazing consists in joining different metal pieces together using a filler material, typically silver, aluminium or copper. In this process, the pieces are not joined through fusion, but using a procedure that is halfway between welding and bonding. In this procedure, a filler material is melted which then penetrates the metal by capillarity. The filler material is then cooled to solidify. This technique is commonly used in the production of compressors for household electrical appliances, radiators, heaters and heat exchangers.
Continuous ovens for brazing
Brazing typically takes place inside continuous ovens for brazing that can reach temperatures of approximately 1150°C. The pieces to be treated move inside the continuous ovens on conveyor belts made in special materials to withstand the high temperatures.
Costacurta’s conveyor belts for high temperatures are dimensioned based on the operating conditions, the sizes of the pieces to be treated and the workload. They are normally made of stainless steel 314 (W. Nr. 1.4841), NiCr 37/18 (W. Nr. 1.4864), INCONEL 600 (W. Nr. 2.4816), INCONEL 601 (W. Nr. 2.4851) and NiCr 80/20 (W. Nr. 2.4869).
Distinctive characteristics of the Costacurta conveyor belts for continuous ovens for brazing:
- Precision of the mesh geometry and quality of the alloys used
- Wide range of mesh available
