Stress Relief Mesh Belt Furnace Welded Steel Parts 650C 36kW 600mm Belt

The SLS stress relief mesh belt furnace is a continuous heat treatment unit designed to relieve internal stresses in welded, formed, machined and cold worked steel assemblies before further processing or final use. Operating at a working temperature of 650C, the furnace heats the parts uniformly, holds them at temperature long enough to relax residual stresses, and then cools them under controlled conditions to avoid introducing new stresses. A wide 600mm mesh belt handles baskets and fixtures of parts, and four controlled zones with plusmn 5C uniformity ensure consistent results across the load. The furnace is widely used to improve dimensional stability, reduce cracking risk and prepare steel fabrications for machining or painting.

• Effective Stress Relief: A controlled 650C soak with a slow, uniform heating and cooling profile relaxes residual stresses from welding, forming, machining and cold work, improving dimensional stability and reducing cracking risk.
• Uniform Four Zone Heating: Four independently controlled zones with PID regulation maintain plusmn 5C uniformity, giving consistent stress relief even for mixed loads of different part sizes and weights.
• Wide 600mm Production Belt: The broad belt accepts baskets, fixtures and tray loaded parts, delivering high hourly throughput for fabricated and machined components of many shapes.
• Controlled Cooling Profile: A regulated cooling section brings the parts down gradually under air, preventing the reintroduction of thermal stresses and preserving the benefits of the relief treatment.
• Energy Efficient Operation: Thick ceramic fiber insulation and efficient heating keep installed power at a moderate 36kW while maintaining a stable stress relief temperature.
• Reliable Process Control: The PLC and touch screen system stores treatment recipes, records temperature profiles for documentation and raises over temperature and thermocouple alarms for safe operation.

This stress relief mesh belt furnace is used to relieve residual stresses in welded steel fabrications, formed and stamped parts, machined components, cold drawn and cold rolled parts, and castings before final machining or assembly. It is common in structural steel fabrication, automotive frame and chassis component production, agricultural machinery, construction equipment and general machinery manufacturing, where dimensional stability and freedom from cracking are essential. Because the process is continuous and uniform, mixed batches of fabricated and machined parts can be treated efficiently, and the parts leave the furnace clean and dimensionally stable.

Every furnace is assembled and temperature tested before shipment to verify uniformity across all four zones and along the full belt width. The delivery includes the furnace main unit, inspection certificates for the major components, a complete technical document set and spare heating modules, thermocouples and fans. The equipment is packed in reinforced wooden cases with moisture protection and bracing for safe ocean transport. Our engineers provide on site installation guidance, commissioning and process development for your parts, and the furnace is backed by a defined warranty and responsive after sales support.

Please provide the part material and dimensions, the fabrication or machining history, the required throughput and the target dimensional tolerances, and we will confirm the zone configuration, belt width, heating power and cooling arrangement. We will then prepare a technical proposal, layout drawing and commercial quotation. Minimum order quantity is one unit, payment terms are T/T, and standard delivery is 60 to 90 days.
