High-Temperature Brazing Furnace
Product Details
2. Product Overview
Our High-Temperature Continuous Brazing Furnaces are engineered for high-strength joining of stainless steel, carbon steel, and copper components. Specifically optimized for copper brazing processes, these furnaces utilize controlled atmospheres (Hydrogen, Nitrogen, or Ammonia Cracking) to produce clean, bright, and oxide-free joints. Whether you are manufacturing plate heat exchangers or automotive fuel rails, our equipment delivers industrial-grade reliability and precision.
3. Key Features & Benefits
-
High-Temperature Mastery: Capable of stable operation at temperatures up to 1150°C (2100°F), ideal for copper-based filler metals and stainless steel parent materials.
-
Atmosphere Purity & Control: Advanced gas management system ensures a reducing atmosphere (H2 or dissociated ammonia), eliminating the need for flux and ensuring a bright surface finish.
-
Ultra-Durable Muffle Design: Features heat-resistant alloy muffles designed to withstand prolonged high-temperature exposure without warping, extending service life.
-
Precision Mesh Belt Drive: High-strength, heat-resistant mesh belts with synchronized tension control ensure smooth transport of heavy or delicate assemblies.
-
Rapid Cooling Technology: Integrated water-cooled jacket sections provide controlled cooling rates, preventing carbon precipitation and maintaining material integrity.
-
Energy-Efficient Multi-Zone Heating: Independent PID control across multiple zones ensures a precise brazing curve and minimizes energy waste.

7. FAQ
Q: What is the best atmosphere for copper brazing stainless steel?
A: For copper brazing, a reducing atmosphere like dissociated ammonia (75% H2, 25% N2) is most common. It prevents oxidation and allows the copper filler to wet and flow perfectly over the stainless steel surfaces without flux.
Q: Can this furnace handle different filler metals?
A: Absolutely. While optimized for copper brazing (melting point ~1085°C), the furnace is also suitable for nickel-based brazing and silver brazing by adjusting the temperature profile and belt speed.
