Gas Fired Annealing Furnace

Annealing Furnace & Oven
The annealing process involves heating metal parts (such as steel, copper, aluminum, or alloys) to a specific temperature below their melting point, holding them at that temperature (soaking), and then cooling at a controlled rate. Gas burners provide direct or indirect heating through combustion, with precise temperature and atmosphere regulation to ensure optimal metallurgical properties.
  • Free combination on demand to meet various working conditions

Features and Construction.

  • High-Efficiency Gas Burners

    Equipped with advanced burners offering high turndown ratios and precise flame control to optimize fuel usage.

  • Robust Furnace Chambers

    Constructed with high-temperature refractory insulation and heavy-duty steel shells to handle continuous operation and thermal cycling.

  • Accurate Temperature Control

    Integrated thermocouple systems, programmable logic controllers (PLC), and optional SCADA/HMI systems ensure tight temperature uniformity (±10°C or better).

  • Optional Protective Atmosphere

    Can be designed for operation in air or under inert/reducing atmospheres (e.g., nitrogen, endothermic gas) to minimize oxidation and scale formation.

  • Batch and Continuous Configurations

    Available in bell-type, box-type, car-bottom, or pusher-style designs to suit various loading methods and production needs.

  • Flexible Loading Capacities

    From small lab-scale units to large industrial furnaces capable of handling several tons per batch.

Applications.

  • Steel Stress Relief and Soft Annealing

  • Copper and Brass Recrystallization

  • Aluminum Annealing for Automotive Components

  • Forgings and Heat-Treated Parts

  • Glass Molds and Castings Annealing

  • Heavy-Duty Machinery Component Processing

Technical Advantages.

  • Lower Operating Costs

    Natural gas or propane is more economical than electricity in many regions, especially for high-temperature, large-volume operations.

  • Faster Heat-Up Times

    Direct flame heating and high BTU input allow for shorter processing cycles.

  • Scalable and Modular Design

    Easily expandable or customized to integrate with conveyors, loaders, or automated handling systems.

  • Durability for Harsh Conditions

    Built to withstand demanding industrial environments with minimal maintenance downtime.

  • Eco-Friendly Options

    Available with low-NOx burners and heat recovery systems to reduce emissions and improve energy efficiency.
