Gas Nitriding Mesh Belt Furnace Steel Components 570C 32kW 400mm Belt Continuous

The SLN gas nitriding mesh belt furnace is a continuous surface hardening unit that uses a controlled ammonia bearing atmosphere at a working temperature of 570C to diffuse nitrogen into the surface of steel components, forming a hard, wear resistant nitrided case without the distortion associated with conventional quenching. A 400mm wide mesh belt conveys the parts through three carefully controlled heating zones, allowing them to pass through the nitriding atmosphere at a belt speed set to achieve the required case depth. Temperature uniformity of plusmn 5C and stable gas composition ensure a consistent, repeatable nitrided layer, while the low process temperature keeps dimensional change to a minimum, making the furnace suitable for finished or near net shape components.

• Controlled Nitriding Atmosphere: A regulated ammonia bearing gas circuit with monitored dissociation maintains a stable nitriding potential, producing a consistent hard surface layer with predictable case depth.
• Low Temperature, Low Distortion: Processing at 570C diffuses nitrogen into the surface without the high temperature quench of conventional hardening, minimizing distortion and allowing near finished parts to be treated.
• Uniform Three Zone Heating: Three independently controlled zones maintain plusmn 5C uniformity, ensuring that all parts in the load develop the same case depth and surface hardness.
• Continuous Case Depth Control: The inverter controlled belt from 50mm to 300mm per minute sets the residence time in the nitriding zone, giving operators direct control over the achieved case depth.
• Gas Tight Safety Design: A sealed furnace chamber, sealed inlet and outlet and interlocked exhaust manage the ammonia atmosphere safely, with alarms for temperature and gas faults.
• Documented Process Control: The PLC touch screen system records temperature and gas data, stores nitriding recipes and supports quality documentation for critical components.

This gas nitriding mesh belt furnace is applied to the surface hardening of steel components such as gears, shafts, camshafts, crankshafts, valve parts, dies, moulds, screws, spindles and wear plates that require a hard, wear resistant surface combined with a tough core and minimal distortion. It is used in automotive, machine tool, textile machinery, hydraulic and general engineering sectors where dimensional accuracy must be preserved. Because nitriding is carried out at a relatively low temperature without quenching, finished or semi finished parts can be treated with very limited dimensional change, making the furnace an efficient continuous solution for critical components.

Each furnace is fully assembled and gas tested before shipment, and the nitriding circuit is verified to confirm atmosphere tightness and stable dissociation control. The delivery includes the furnace main unit, inspection certificates for major components, a complete technical document set and spare heating modules and thermocouples. The equipment is packed in reinforced wooden cases with moisture protection for safe international transport. Our engineers provide on site installation, commissioning and process development to achieve your required case depth and hardness, and the furnace is supported by a defined warranty and responsive service.

Please provide the component material, the required case depth and surface hardness, the part dimensions and the target throughput, and we will confirm the zone arrangement, heating power, gas circuit and belt speed range. We will then prepare a technical proposal, general arrangement drawing and commercial quotation. Minimum order quantity is one unit, payment terms are T/T or L/C, and typical delivery is 80 to 110 days.
