Main Applications

The circular melting furnace is primarily used for the high-temperature melting process of solid aluminum and aluminum alloy ingots. It is widely applied in the melting and refining processes of recycled aluminum and is particularly suitable for the initial melting stage in the production of high-quality aluminum alloy ingots, bars, sheets, rims, and castings. This equipment is highly efficient, energy-saving, and environmentally friendly. Additionally, it can be used for the melting process of other non-ferrous metals such as copper, zinc, and lead. Its design focuses on performance optimization, energy efficiency, and environmental protection requirements, providing an ideal solution for the metal processing industry.
