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.
Key Features of a Gas Fired Melting Furnace

Why Choose Us?
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.
Why Energy Efficiency Matters in Gas Fired Melting Furnaces
Upgrading to a Gas Fired Melting Furnace can significantly reduce your energy consumption. The furnace’s dual regenerative heat exchange system recycles the heat that would otherwise be lost through exhaust gases. This helps to reduce energy waste by up to 30%, offering you substantial cost savings over time. Whether you are melting aluminum, copper, or other metals, this innovative feature allows for a more environmentally friendly and budget-conscious approach to metal melting.
What Makes Gas Fired Melting Furnaces Stand Out?
1. Faster, More Efficient Metal Melting
Thanks to its superior heat insulation and rapid heating capabilities, a Gas Fired Melting Furnace heats up quickly, melting metal faster than conventional furnaces. For industries like die casting, where speed and precision are critical, this feature can boost productivity significantly.
2. Improved Metal Purity
The furnace’s advanced heat management system minimizes oxidation, especially with metals like aluminum, which is highly prone to oxidation. This ensures your metal remains pure during the melting process, which is especially important for industries requiring high-quality metal parts.
3. Long-Term Durability
A Gas Fired Melting Furnace is built to last. The combination of high-performance graphite crucibles, upgraded burners, and advanced thermal insulation ensures that the furnace lasts longer, requiring fewer repairs and replacements. This makes the furnace a cost-effective investment over time.
Applications of Gas Fired Melting Furnace
A Gas Fired Melting Furnace is ideal for industries that require high-quality molten metal. Some key applications include:
| Industry | Application |
|---|---|
| Die Casting | Provides consistent, high-temperature molten metal, ensuring the precision required for high-quality parts. |
| Aluminum Foundries | Perfect for continuous operations that demand reliable and uniform temperature control. |
| Automotive and Aerospace | Used for metal melting applications where high precision and purity are critical. |
| Recycling | Ideal for recycling scrap metal and turning it into reusable materials. |
Cost-Saving Advantages of Gas Fired Melting Furnace
| Advantage | Benefit |
|---|---|
| Energy Efficiency | Reduces fuel costs by up to 30% through heat recovery. |
| Fewer Maintenance Costs | Durable components such as high-performance burners and graphite crucibles lead to lower maintenance costs. |
| Longer Furnace and Crucible Lifespan | With enhanced durability, the furnace and crucibles last longer, reducing the need for frequent replacements. |
