Round Aluminum Melting / Holding Furnace

Main Applications

The round furnace melts and refines solid aluminum, alloy ingots and recycled aluminum for ingot, billet, sheet, wheel and die-casting lines. Its circular body suits compact layouts and can be configured by capacity, fuel, lining and molten-metal transfer method. It can also be applied to copper, zinc and lead.

Overseas Project Support

For export projects, Lanyu can configure the round aluminum melting and holding furnace around local fuel or power conditions, plant layout, automation level, operator workflow and environmental requirements. The round furnace layout can be matched with compact workshops, dedicated alloy lines or molten metal transfer requirements.
