Melting Capacity and Casting Process Integration

In recycled aluminum and aluminum alloy production, a melting furnace must do more than melt raw materials. The process may also include skimming, refining, temperature adjustment, and preparation of molten aluminum for casting.

The PDF describes a rectangular, single-chamber tilting aluminum melting furnace with regenerative natural gas combustion. It is designed for melting aluminum and aluminum alloy scrap and for subsequent molten aluminum treatment before casting.

≥4 t/h Melting Rate

The specified performance guarantee includes a melting rate of ≥4 t/h. The acceptance test uses 100% aluminum ingots as the raw material, with melting time calculated until the molten aluminum reaches 720°C.

For overseas B2B buyers, this testing condition is important when comparing an aluminum melting tilting furnace with other equipment. Actual production performance can vary according to raw material composition, charging frequency, target temperature, and operating conditions. Therefore, the ≥4 t/h figure should be understood as a performance guarantee under the specified test conditions.

Regenerative Combustion System

The furnace uses a pair of regenerative natural gas burners that alternate between combustion and exhaust. The system recovers heat from flue gas to preheat combustion air. The proposal specifies combustion air preheating of around 1000°C, main exhaust temperature around 200°C, and stated regenerative heat recovery efficiency above 85%.

Hydraulic Tilting for Casting Integration

The furnace uses hydraulic tilting with proportional speed control. A laser rangefinder continuously detects molten aluminum level, while an encoder measures the furnace tilting angle. The electronic closed-loop system specifies molten aluminum level control accuracy of ±2 mm.

For aluminum casting operations, these specifications provide practical reference points for evaluating melting capacity, molten aluminum control, and integration between the regenerative tilting aluminum melting furnace and downstream casting equipment.
