In aluminum casting operations, transferring molten aluminum between melting furnaces and holding furnaces can lead to heat loss, oxide formation, and increased operator safety risks. An система алюминиевых желобов provides a continuous and controlled method for transporting molten aluminum while maintaining temperature stability and reducing manual handling.

AdTech aluminum launder segments are designed for connecting melting furnaces with holding furnaces in die casting and aluminum casting production lines, helping foundries improve melt transfer efficiency, reduce energy consumption, and maintain better molten aluminum quality.

What Is an Aluminum Launder System Used For?

An aluminum launder is a refractory-lined channel system used to transfer molten aluminum from one furnace to another without using transfer ladles or forklifts.

In a typical die casting application, the launder system connects an existing gas-fired melting furnace with multiple electric resistance holding furnaces located near die casting machines. Molten aluminum flows continuously through the insulated launder, reducing the need for repeated pouring operations.

Compared with traditional transfer methods, an aluminum launder system helps:

Reduce molten aluminum handling steps
Minimize temperature loss during transfer
Lower oxidation caused by turbulence
Improve workplace safety by reducing manual molten metal transportation

How Does an Aluminum Launder Improve Casting Efficiency?

Traditional molten aluminum transfer usually requires:

Pouring aluminum from the melting furnace into a transfer ladle
Moving the ladle to the holding furnace
Pouring aluminum again into the holding furnace

Each pouring operation exposes molten aluminum to air, increasing the risk of oxide formation and inclusions.

With an aluminum launder system, molten aluminum can flow directly from the melting furnace to holding furnaces. By eliminating unnecessary pouring steps, the system helps reduce:

Aluminum oxide generation
Hard spots caused by oxide inclusions
Heat loss during transportation
Labor requirements for molten metal handling

Key Features of Aluminum Launder Segments

Air Cylinder Operated Covers for Easy Maintenance

The launder system can be equipped with air cylinder-operated covers and holding furnace heating lids, allowing operators to easily access the system for cleaning, inspection, and maintenance.

High Insulation Performance with Calcium Silicate Lining

The launder uses highly insulated calcium silicate board lining materials that provide:

Excellent thermal insulation
Reduced heat loss during aluminum transfer
Natural non-wetting properties with molten aluminum
Easier cleaning and maintenance

This helps maintain molten aluminum temperature stability throughout the transfer process.

Bolt-On End Cap Design for Flexible Metal Supply

A working tap integrated into the bolt-on end cap allows molten aluminum supply to remote holding furnaces that are not directly connected to the main launder system.

This provides greater flexibility when expanding or modifying aluminum casting production lines.
