Rectangular Aluminum Melting / Holding Furnace

Primary Applications

The rectangular melting furnace is primarily used for high-temperature melting of solid aluminum and alloy ingots, with functions to maintain the temperature of molten aluminum. It also effectively handles the melting of difficult-to-melt alloys. This equipment is particularly suitable for the melting and refining processes of recycled aluminum.

In addition, this advanced, energy-efficient, and environmentally friendly device excels in the initial melting stage required for producing high-quality aluminum alloy ingots, aluminum alloy rods, aluminum plates, aluminum strips, aluminum wheels, and aluminum die-cast products. It not only meets the needs of aluminum alloy melting but can also be extended to melting processes for other non-ferrous metals such as copper, zinc, and lead.

Overseas Project Support

For export projects, Lanyu can configure the rectangular aluminum melting and holding furnace around local fuel or power conditions, plant layout, automation level, operator workflow and environmental requirements. It is suitable for plants that need a stable molten aluminum supply, flexible furnace sizing and integration with casting or transfer systems.
