Controlled Molten Aluminum Transfer

In aluminum casting operations, melting is only one stage of the furnace process. After melting, molten aluminum must be transferred to downstream casting equipment. For this reason, hydraulic tilting, molten aluminum level detection, and safety control are important technical features of an aluminum melting tilting furnace.

For aluminum foundries processing aluminum and aluminum alloy scrap, these parameters can be considered together with melting rate and gas consumption when evaluating furnace equipment.

Hydraulic Tilting for Molten Aluminum Discharge

The furnace described in the PDF uses a rectangular, single-chamber hydraulic tilting structure with two hydraulic tilting cylinders. Tilting speed can be continuously adjusted through a proportional valve and coordinated with casting speed or controlled by the casting machine. The hydraulic system has a design pressure of 16 MPa.

For a hydraulic tilting aluminum melting furnace, this configuration connects furnace movement with the molten aluminum discharge process. The tilting operation can therefore be adjusted according to process requirements rather than relying only on a fixed tilting action.

Tilting Speed and Casting Rhythm

The proposal specifies a fixed fast lifting and lowering speed of 100 mm/min and an emergency return speed of ≥500 mm/min. Tilting speed can be continuously adjusted through the proportional valve according to operating requirements.

When evaluating a tilting aluminum melting furnace, buyers can therefore examine hydraulic pressure, cylinder configuration, and tilting-speed control in addition to furnace capacity.

Laser Level Detection and ±2 mm Control Accuracy

The furnace uses a laser rangefinder to continuously detect molten aluminum level, while an encoder measures the furnace tilting angle. The electronic closed-loop control system specifies molten aluminum level control accuracy of ≤±2 mm.

Two stainless-steel probes are also provided as maximum-level limits. If the rangefinder fails, the furnace tilts excessively, or the maximum liquid level is reached, the system is designed to initiate an automatic return operation.

Why Molten Aluminum Level Control Matters

For an aluminum casting line, molten aluminum transfer needs to coordinate with downstream equipment. Level-control accuracy, tilting-angle detection, and protection logic can therefore serve as measurable technical parameters when evaluating an aluminum melting furnace.

The ≤±2 mm figure is the control-accuracy specification stated in the PDF and should be evaluated together with the actual casting equipment, molten aluminum temperature, and site conditions.

Regenerative Combustion for the Melting Process

The furnace also uses a regenerative natural gas combustion system. A pair of burners alternates between combustion and exhaust, recovering heat from flue gas through regenerative media and using it to preheat combustion air. 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. The test uses 100% aluminum ingots and defines the melting endpoint as molten aluminum reaching 720°C.

For B2B buyers evaluating an aluminum melting tilting furnace, melting capacity, combustion configuration, hydraulic tilting, and molten aluminum level detection can be reviewed together as part of the technical specification.
