Annealing Mesh Belt Furnace Stainless Steel Parts 1050C 45kW Bright Inverter

The SLA continuous mesh belt annealing furnace is a bright annealing platform designed for stainless steel, nickel based alloy and soft magnetic components that must be delivered with a clean, oxide free surface. A 450mm wide nickel chromium belt transports parts through seven controlled heating zones, a rapid cooling section and a discharge zone, all within a nitrogen or nitrogen hydrogen protective atmosphere. Operating at a bright annealing temperature of 1050C, the furnace relieves internal stresses, refines grain structure and restores ductility without producing surface scale. The inverter driven drive system and precisely regulated atmosphere make the unit equally suitable for continuous volume production and for mixed, medium sized batches where metallurgical consistency is essential.

• Bright Annealing Without Scale: A sealed furnace tunnel with controlled atmosphere and balanced inlet and outlet curtains prevents surface oxidation, so stainless steel and alloy parts emerge bright, clean and ready for further processing.
• 1050C Seven Zone Uniformity: Seven heating zones with independent K type thermocouples and PID controllers maintain temperature uniformity of plusmn 3C, giving consistent recrystallization and grain structure along the length of the belt.
• Protective N2 H2 Atmosphere: A multi path gas system with individual flow meters maintains a controlled nitrogen or nitrogen hydrogen atmosphere that protects the workpiece surface during the high temperature anneal.
• Extended Cooling Section: A long controlled cooling zone allows the parts to cool gradually under atmosphere, preventing re oxidation and controlling the final hardness and microstructure.
• Inverter Driven Belt Transport: The variable frequency transmission provides smooth belt speeds from 30mm to 200mm per minute, letting operators tune residence time to match different material gauges and part weights.
• Integrated Process Data Logging: The PLC and touch screen control system records temperature and alarm events, supports multiple annealing recipes and offers MES communication for complete production traceability.

This bright annealing mesh belt furnace is used for annealing and solution treatment of stainless steel fasteners, stampings, springs, clips and surgical instrument blanks, as well as the final anneal of soft magnetic alloy laminations and nickel based alloy components. It supports stress relief annealing after cold working, recrystallization annealing to restore ductility and bright annealing where surface quality is a customer requirement. Typical users include manufacturers of stainless steel hardware, automotive trim and belt components, electrical steel laminations and precision metal parts. Because the furnace anneals continuously under atmosphere, it improves both the mechanical properties and the cosmetic quality of the finished components.

Every furnace is pre assembled and temperature tested before shipment, and the atmosphere chamber is pressure tested to guarantee a reliable, gas tight seal. The delivery package includes the furnace main unit, inspection certificates for major components, a complete technical document set and spare heating modules, thermocouples and relays. The equipment is packed in reinforced wooden cases with moisture barriers to withstand long distance ocean freight. Our engineering team provides on site installation guidance, functional commissioning and annealing process development support, and the machine is backed by a defined warranty and a long term spare parts commitment.

Please supply the component material, maximum part size, required throughput and the target surface and mechanical properties, and we will recommend the correct belt width, zone count, cooling length and atmosphere arrangement. We will then issue a technical offer, general arrangement drawing and commercial quotation for your evaluation. Minimum order quantity is one unit, payment terms are T/T or L/C, and the standard lead time is 80 to 110 days. Contact our engineers today for a detailed bright annealing proposal.
