Reduced Atmosphere Mesh Belt Furnace Copper Brazing 1050C 40kW Exothermic Gas

The SLR reduced atmosphere mesh belt furnace uses a generated exothermic or endothermic gas atmosphere to braze copper and to anneal steel parts without the oxidation and scaling that occur in air. Operating at a working temperature of 1050C, the furnace produces strong, clean copper brazed joints and bright annealed surfaces at a lower atmosphere cost than hydrogen based systems, making it an economical choice for many production brazing and annealing lines. A 360mm wide nickel chromium mesh belt conveys the workpieces through six controlled zones and a cooling section, while the sealed tunnel and balanced gas curtains keep the reducing atmosphere stable along the entire furnace length, delivering consistent metallurgical results across large production batches.

• Economical Reducing Atmosphere: A generated exothermic or endothermic gas atmosphere protects the workpieces from oxidation, delivering clean copper brazed joints and bright surfaces at a lower operating cost than pure hydrogen systems.
• 1050C Brazing and Annealing: Six heating zones provide a controlled profile up to 1050C, supporting both copper brazing of steel assemblies and oxide free annealing of steel and alloy parts.
• Stable Sealed Tunnel: A gas tight chamber with inlet and outlet curtains and interlocked exhaust maintains a positive pressure reducing atmosphere that keeps air out and prevents scale formation.
• Reliable Belt Transport: The inverter driven mesh belt travels smoothly from 50mm to 300mm per minute under sprocket chain guidance, keeping parts stable and repeatable through the hot zone.
• Controlled Cooling: A protective atmosphere cooling section lowers the parts gradually, preserving the bright surface and the mechanical properties established during the hot cycle.
• Robust Industrial Control: The PLC and touch screen control system stores brazing and annealing recipes, monitors temperature and gas flow, and raises alarms for any deviation to protect both parts and equipment.

This reduced atmosphere mesh belt furnace is used for copper brazing of steel assemblies such as tubular frames, chains, brackets, motor housings and radiator components, and for oxide free bright annealing of steel stampings, wire products and machined parts. It is well suited to general metalworking operations that require a clean, bright surface after brazing or annealing but prefer a generated gas atmosphere to the higher cost and handling requirements of pure hydrogen. Manufacturers of furniture hardware, bicycle and motorcycle components, appliance parts and industrial chains use the furnace as the core of a continuous brazing or bright annealing line with predictable cycle times and stable quality.

Each furnace is assembled and gas tested before shipment to confirm the integrity of the sealed atmosphere chamber and the stability of the reducing gas profile. The delivery includes the furnace main unit, inspection certificates for the principal components, a full technical document set and spare heating modules and thermocouples. The equipment is packed in wooden cases with moisture barriers and cushioning for safe ocean transport. We provide on site installation guidance, commissioning and process development for your brazing and annealing requirements, and the furnace carries a defined warranty with responsive after sales support.

Please supply the assembly drawings or part list, the base metal and filler metal, the required joint strength, the throughput and the intended atmosphere, and we will confirm the zone arrangement, heating power and gas circuit. We will then prepare a technical proposal, layout drawing and commercial quotation for your review. Minimum order quantity is one unit, payment terms are T/T or L/C, and standard delivery is 80 to 110 days. Contact us today for a cost effective brazing and annealing solution.
