Iron Powder Reduction Mesh Belt Furnace 950C 40kW Hydrogen 400mm Belt Conveyor

The SLR iron powder reduction mesh belt furnace is designed to reduce iron oxide and other metal oxide powders to their metallic form in a high purity hydrogen atmosphere at a working temperature of 950C, producing low oxygen, high compressibility powders for powder metallurgy and metal injection molding feedstock. A 400mm wide nickel chromium mesh belt carries a shallow, uniform bed of powder through six controlled heating zones, then through a protective cooling section, all within a sealed hydrogen atmosphere that is maintained by balanced inlet and outlet curtains. Temperature uniformity of plusmn 3C and stable gas composition are essential for complete, uniform reduction, and the furnace is engineered to deliver both consistently at production scale.

• Hydrogen Reduction Atmosphere: A gas tight furnace chamber with balanced curtains maintains a high purity hydrogen atmosphere that reduces oxide powders fully while protecting the freshly formed metal from re oxidation.
• Uniform 950C Reduction: Six independently controlled heating zones with PID control maintain plusmn 3C uniformity, ensuring complete and consistent reduction across the full belt width and depth.
• Controlled Cooling Under Protection: A protective atmosphere cooling section lowers the reduced powder gradually, preventing re oxidation and stabilizing the powder before it leaves the furnace.
• Even Powder Bed Handling: The 400mm belt and uniform gas distribution are designed to carry a shallow, level powder bed, promoting even reduction and consistent product quality.
• Reliable Belt Drive: The large wrap angle friction drive and inverter controlled transmission move the belt smoothly from 30mm to 200mm per minute for stable, repeatable operation.
• Secure Gas and Process Control: The PLC touch screen system manages reduction recipes, monitors temperature and gas flow, and provides interlocked alarms for over temperature, low pressure and gas faults.

This iron powder reduction mesh belt furnace is used for the reduction of iron oxide powders to sponge iron powder, the reduction of copper, cobalt, tungsten and other metal oxide powders, and the final reduction and annealing of atomized powders used in powder metallurgy, metal injection molding and additive manufacturing feedstock. It also supports the reduction annealing of mill scale and process residues. Powder producers rely on its stable hydrogen atmosphere and uniform high temperature zone to achieve low oxygen content and high compressibility, while the continuous belt design allows consistent, high volume production of high quality reduced powders.

Every furnace is assembled and pressure tested before shipment, and the hydrogen atmosphere chamber is verified for tightness to guarantee safe, stable reduction conditions. 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 and internal bracing to withstand international transport. Our engineers provide on site installation, commissioning and process development for your powders and reduction targets, and the furnace is backed by a defined warranty and dependable service.

Please provide the feed powder type and oxide content, the required oxygen level and particle characteristics, the throughput and the intended atmosphere, and we will confirm the zone configuration, heating power, cooling section and gas circuit. 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 the standard lead time is 90 to 120 days.
