Product Functions
Harnessing globally leading dual-regenerative combustion and intelligent control technology, we deliver an ultra-efficient, high-performance, and exceptionally stable aluminum melting solution—slashing comprehensive operating costs by up to 40%.
Key Benefits
Extreme Energy Efficiency
- Achieve up to 90% thermal utilization with exhaust temperatures below 80°C. Reduce energy consumption by 30-40% compared to conventional furnaces.
Rapid Melting Speed
- Equipped with an exclusive 200kW high-speed burner, our system delivers industry-leading aluminum heating performance and significantly boosts productivity.
Eco-Friendly & Low Emissions
- NOx emissions as low as 50-80 mg/m³ meet strict environmental standards and support your corporate carbon neutrality goals.
Fully Automated Intelligent Control
- Features PLC-based one-touch operation, automatic temperature regulation, and precise air-fuel ratio control—no need for dedicated operators.
Globally Leading Dual-Regenerative Combustion Technology
How It Works
Our system uses alternating left and right burners—one side burns while the other recovers heat. Switching every 60 seconds, it preheats combustion air to 800°C while keeping exhaust temperatures under 80°C, maximizing heat recovery and efficiency.
Reliability & Innovation
- We replaced failure-prone traditional mechanisms with a servo motor + specialized valve system, using algorithmic control to accurately regulate gas flow. This dramatically enhances lifespan and reliability.
- Advanced diffusion combustion technology limits NOx emissions to 50-80 mg/m³, far exceeding national standards.
- Each furnace helps reduce CO₂ emissions by 40% and NOx by 50%—lowering costs for your business while supporting national carbon peak goals.
Applications & Materials
Ideal For: Die-casting factories, automotive parts, motorcycle components, hardware manufacturing, and metal recycling.

If you're in the business of refining and casting gold bars, the Gold Barring Furnace is the core piece of equipment you need. Designed for high-precision metal processing, these furnaces combine flexibility, safety, and efficiency to meet the rigorous demands of modern gold production.
Why Choose a Gold Barring Furnace?
- Tilt Design for Safety and Precision
The gold barring furnace incorporates a center tilt design that ensures safer and more controlled metal pouring. This reduces the risk of spillage or accidents, a crucial feature when handling molten gold at temperatures up to 1300°C. With both hydraulic and motor-driven tilt options available, users can choose the method that best fits their production scale and safety requirements. - Multiple Energy Options
Flexibility in energy sources is a key advantage. Gold barring furnaces support natural gas, LPG, diesel, electric and can be equipped with AFR burners to optimize combustion efficiency. This variety allows gold production companies to adapt to their local energy supply and reduce operational costs. - High-Efficiency Burners
Equipped with advanced burners that operate efficiently under diverse working conditions, these furnaces not only maximize energy usage but also minimize environmental impacts. The burner design helps reduce harmful emissions, aligning with modern sustainability standards. - Modular Design for Easy Integration
The furnace features a modular design that can easily integrate into existing facilities. Its adaptable specifications make it suitable for small-scale operations as well as large refineries, catering to a wide range of production needs. Whether producing gold bars daily or handling specific smelting tasks, this furnace meets the highest industry standards.
Application and Benefits
This furnace is ideal for gold bar production companies of various sizes. Its core strengths include:
- Efficient and Environmentally Friendly: Advanced burner technology ensures energy savings and low emissions.
- Safe and Easy to Operate: With a tilt mechanism designed for both safety and precision, it makes handling molten gold much simpler.
- Low Maintenance Costs: The durable electric gear drive system ensures long-term, stable operation, reducing both downtime and maintenance costs.

From efficient energy use to reliable performance, we ensure that our furnaces meet the most demanding production environments.
Solving Three Major Problems in Traditional Aluminum Melting Furnaces
In traditional aluminum melting furnaces used for gravity casting, there are three big issues that cause trouble for factories:
1. Melting takes too long.
It takes more than 2 hours to melt aluminum in a 1-ton furnace. The longer the furnace is used, the slower it gets. It only improves a little when the crucible (the container that holds the aluminum) is replaced. Because melting is so slow, companies often have to buy several furnaces to keep production going.
2. Crucibles don’t last long.
The crucibles wear out quickly, get damaged easily, and often need to be replaced.
3. High gas consumption makes it expensive.
Regular gas-fired furnaces use a lot of natural gas—between 90 and 130 cubic meters for every ton of aluminum melted. This leads to very high production costs.
