Core Technology

Negative-Pressure Combustion and Charging Tower Melting System

Denova’s centralized melting furnace combines negative-pressure combustion technology, a specially designed charging tower, and separated melting and holding zones. Hot combustion gases are utilized to preheat the aluminum charge in the upper charging tower before melting, while the separated melting and holding areas support continuous molten aluminum production and stable holding conditions. This design improves heat utilization, shortens the high-temperature melting stage, and helps reduce oxidation and energy consumption.

Performance Benefits

Melting Capacity up to
6.5 t/h

Available melting capacities range from approximately 0.5 to 6.5 tons per hour, supporting different production scales and high-throughput molten aluminum supply.

Natural Gas Consumption as Low as 50 Nm³/t

Efficient charge preheating and optimized combustion improve thermal utilization, enabling natural gas consumption as low as 50 Nm³ per ton of molten aluminum under applicable operating conditions.

Aluminum Loss as Low as 0.8%

Aluminum loss can be controlled at approximately 0.8% when using 100% aluminum ingots, and approximately 1.2% with a charge mix of 50% ingots and 50% return material.

Refractory Lining Life of Approximately 8-10 Years

A durable refractory design supports long-term furnace operation, helping reduce major maintenance frequency and lifecycle maintenance requirements.

Typical Applications

High-volume aluminum die casting production

Continuous molten aluminum supply for production lines

Large-scale aluminum alloy processing
