Rectangular Smelting Furnace Group / 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.
