Connecting Aluminum Melting with Casting

In aluminum alloy melting and casting operations, an aluminum melting tilting furnace needs to do more than melt aluminum. The furnace must also transfer molten aluminum in a controlled way to downstream casting equipment.

The furnace described in the PDF uses a rectangular, single-chamber hydraulic tilting structure. It is designed for melting aluminum and aluminum alloy scrap, followed by skimming, refining, and temperature adjustment before molten aluminum is discharged for the next process.

Hydraulic Tilting for Controlled Discharge

This hydraulic tilting aluminum melting furnace uses two hydraulic tilting cylinders and proportional-valve control for continuous adjustment of tilting speed. The proposal states that the tilting speed can be coordinated with casting speed and can also be controlled by the casting machine. The fixed fast lifting and lowering speed is 100 mm/min, while the emergency return speed is specified at ≥500 mm/min. The hydraulic system design pressure is 16 MPa.

For a casting line, this arrangement allows molten aluminum discharge to be coordinated with downstream process requirements rather than relying only on manual furnace movement.

Molten Aluminum Level Accuracy of ±2 mm

The furnace uses a laser rangefinder to continuously detect molten aluminum level and an encoder to measure the furnace tilting angle. An electronic closed-loop control system is specified, with molten aluminum level control accuracy of ≤±2 mm. Two stainless-steel probes provide maximum-level protection, while automatic return functions are specified for rangefinder failure, excessive tilting, or maximum liquid level conditions.

These features provide measurable parameters for evaluating the integration of an aluminum melting furnace with downstream casting equipment.

Regenerative Combustion for the Melting Process

The furnace also uses regenerative natural gas combustion. A pair of burners alternates between combustion and exhaust while regenerative media recover heat from flue gas for combustion-air preheating. The proposal specifies combustion-air preheating around 1000°C, main exhaust temperature around 200°C, and stated heat recovery efficiency above 85%.

The performance guarantee specifies a melting rate of ≥4 t/h and unit gas consumption of ≤65 Nm³/t-Al under defined test conditions.

For overseas B2B buyers, these parameters can be considered together when evaluating a tilting aluminum melting furnace for aluminum melting and casting-line integration.
