In aluminum rod, wire, and electrical conductor manufacturing, the melting stage determines melt purity, energy cost, metal yield, and continuous line uptime. The RLB Aluminum and Aluminum Alloy Melting Furnace series delivers a complete family of industrial melting and holding systems engineered to convert aluminum ingots, recovery materials, recycled packaging scrap, crushed castings, and lightweight waste into high-purity molten aluminum suitable for 1#, 3#, 5#, 6#, and 8# series alloys — including EC1350, 5005/5154, 6101/6201, 8176/8030, and related high-conductivity grades used in AAC, AAAC, and ACSR conductors.
Available in sky-melting + round holding, double-chamber, rectangular tilting, and fixed configurations, these furnaces combine advanced regenerative combustion, precise PID temperature control (±5 °C uniformity), and intelligent HMI + PLC automation. The result is 20–40% energy savings versus conventional furnaces, oxidation losses typically below 1.5% (often 0.8–1.2% under optimized conditions), and full compliance with European and American standards — while supporting Saudi Green Initiative and Vision 2030 low-carbon objectives.
Regenerative Combustion Technology – Proven Energy & Emission Performance
The core of every RLB furnace is a dual-bed regenerative combustion system. High-temperature flue gas (typically 1100–1200 °C) transfers heat to ceramic regenerator media, then exits at below 150–230 °C. Simultaneously, combustion air is preheated to approximately 700–900 °C. This recovers over 90% of waste heat, raises thermal efficiency to 75–85% (versus 50–55% for traditional cold-air furnaces), and cuts natural gas consumption to roughly 45–60 m³ per ton of aluminum (versus 75–90 m³).
Additional metallurgical and process advantages include:
- Precise PID temperature control with ±5 °C bath uniformity ensures consistent alloy chemistry for high-conductivity EC1350 and 6xxx/8xxx series rods.
- Optional electromagnetic stirring promotes rapid homogenization, reduces temperature gradients, and minimizes oxide formation.
- Online rotary degassing (inert gas) and ceramic foam filtration systems routinely achieve hydrogen levels below 0.15 ml/100 g Al and low inclusion counts critical for electrical conductors.
- Oxidation/burn-off losses typically <1.5% (frequently ≤0.8–1.2%), maximizing yield from contaminated packaging scrap and lightweight waste.
- Heavy-duty steel shell with premium multi-layer refractory lining delivers long service life under continuous high-temperature operation in GCC climates.
- Low-NOx staged combustion and reduced flue-gas volume support stringent environmental regulations.

Advanced Configurations Tailored to Production Scale
Four proven configurations cover continuous rod lines and flexible scrap-based operations:
- Sky Melting + Round Holding Furnace — Ideal for continuous aluminum rod production at 5–10 t/h. Continuous melting with separate holding and refining chambers maintains steady metal supply to the casting wheel.
- Double-Chamber Melting Furnace — High flexibility for mixed ingot and scrap charges. Alternating melting and refining cycles support uninterrupted downstream casting.
- Rectangular Tilting Furnace (Rod/Bar) — 10–35 t capacity with hydraulic tilting and laser flow control for precise, stable delivery of molten aluminum to rod or bar casting systems.
- Rectangular Fixed/Tilting Furnace (Ingot/Bar/Strip) — 4–20 t/h melting rate (7–100 t total capacity) for packaging scrap, crushed castings, and lightweight waste conversion into ingots, bars, plates, or tape.
Core Features Across All Models
Regenerative burners compatible with natural gas, LPG, heavy oil, diesel, or coal gas; intelligent HMI + PLC with recipe storage, real-time monitoring, data logging, and full-line synchronization; hydraulic tilting + laser flow control; optional electromagnetic stirring, online degassing, and ceramic foam filtration; automated scrap charging systems available to reduce labor and improve safety.

Seamless Integration with Continuous Casting & Rolling Lines
Every melting furnace is engineered for direct integration with aluminum rod continuous casting and rolling lines. Molten metal is delivered via matched launders and flow-control systems to produce high-quality 9.5 mm, 12 mm, and 15 mm EC-grade and alloy rods for AAC, AAAC, and ACSR conductors. Most installations achieve seamless synchronization with less than 4 hours of downtime.

Optional stirring, degassing, and filtration packages, combined with continuous casting machines or ingot casting lines, create complete turnkey aluminum production solutions.
Sustainability, ROI & Vision 2030 Alignment
- Energy Savings: 20–40% lower fuel consumption vs conventional furnaces; typical payback 12–20 months.
- Low Carbon Footprint: Regenerative heat recovery + low NOx burners support Saudi Green Initiative and Vision 2030 goals.
- High Metal Yield: Oxidation losses <1.5% and excellent scrap utilization maximize profitability.
- Reduced Emissions: Flue gas <150 °C with optional after-treatment meets stringent GCC environmental regulations.
