Our advanced Furnaces are specifically engineered for the precise heat treatment of aluminum products, delivering unparalleled performance in both aging and annealing With Solutionizing and Degassing processes. Designed to handle the rigorous demands of the wire, cable, and aluminum processing industries, these custom-built furnaces ensure uniform temperature distribution for optimal material strength, flexibility, and complete degassing.

1. Batch Type – Aluminum Aging cum Annealing Bogie Hearth Furnace

(Available in Electric & Gas-Fired Compositions)

• Overview: Built with a track-mounted, motorized hearth (car bottom / trolley), this furnace allows heavy coils, spools, and wire baskets to be loaded mechanically outside the chamber before being driven inside.

• Core Functions:

  • Annealing: Softens cold-worked aluminum wire, stress-relieving the grain structure to restore electrical conductivity and mechanical ductility.

  • Artificial Aging: Performs precise low-temperature precipitation hardening (typically for AAAC / 6000-series alloy conductors).

• Heating System:

  • Electric: Utilizes high-grade resistance elements with thyristor (SCR) power control for clean, high-precision heating.

  • Gas-Fired: Uses direct-fired or indirect radiant tube burners with proportional combustion controls for lower operational energy costs.

• Key Feature: Equipped with high-volume recirculation fans to maintain tight temperature uniformity , critical for consistent alloy temper.

2. Continuous Aging cum Annealing with Solutionizing Type Furnace

(Available in Electric & Gas-Fired Compositions)

Designed for high-volume inline production, this continuous furnace processes wire rods, spools, or strands through defined temperature zones via roller hearths, mesh belts, or overhead chain conveyors.

• Function: Performs Solution Heat Treatment (heating aluminum alloys to around 500 deg C to dissolve alloying elements into a solid solution) prior to controlled aging or annealing.

Variations:

• (a) With Quenching System:

  • Integrates a rapid water-spray or drop-quench tank immediately at the outlet of the heating chamber.

  • Purpose: Rapidly freezes the supersaturated solid solution (SSSS), preventing premature precipitation—a required step before artificial aging to maximize wire tensile strength and conductivity.

• (b) Without Quenching System:

  • Utilizes controlled air-cooling or inert gas forced-cooling zones instead of liquid quenching.

  • Purpose: Ideal for standard full-annealing, soft-temper wire production, and gentle stress-relief where thermal shock and distortion must be avoided.

3. Wire Degassing / Cable Post-Curing Furnace

• Overview: A specialized thermal processing oven designed at 75- 120 Deg C primarily for post-processing XLPE/extruded insulated cables and pre-treating raw wire conductors.

• Core Functions:

  • Degassing: Thermally drives out residual volatile organic compounds (such as methane and peroxide byproducts) generated during cross-linking in heavy power and EHV cable insulation.

  • Post-Curing & Moisture Removal: Eliminates trapped gases and absorbed moisture from wire strands before jacketing or stranding, improving dielectric properties and insulation bonding.

• Key Feature: Built with heavy-duty exhaust handling, fresh-air purging circuits, and integrated LEL (Lower Explosive Limit) safety monitoring systems to safely handle flammable gas evacuation.

4. Custom Chamber for Stress Relieving / Other Heating Process Furnace

• Overview: Modular, tailor-made box, pit, or chamber furnaces designed to fit non-standard coil sizes, specialized production layouts, or unique metallurgical thermal cycles.

• Core Functions:

  • Stress Relieving: Low-temperature heat treatment 150-300 Deg C to relieve residual internal mechanical stresses induced during wire drawing, stranding, compacting, or coiling without compromising metallurgical temper.

  • Miscellaneous Processes: Reel preheating prior to extrusion line feeding, protective coating curing, or custom thermal testing.

• Key Feature: Highly customizable airflow configurations, specialized atmosphere control (e.g., nitrogen purging to prevent surface oxidation), and multi-zone PID program controls tailored to specific client specifications.
