NEU-SANKEN has developed various types of reverberatory furnaces according to market demand and improved the upstream and downstream supporting equipment to form a recycled aluminum production line with our own characteristics. It can process all kinds of waste aluminum materials containing iron, oil, and impurities from the market, bringing huge economic benefits to customers. We have a complete range of reverberatory furnaces, including circular furnaces, square furnaces, tilting furnaces, side - well furnaces, double - chamber furnaces, multi - chamber furnaces, rotary furnaces, UBC Decoating kilns, dust - removal equipment, etc. The melting capacity of the reverberatory furnace ranges from 0.5 to 12 t/h, and the holding capacity ranges from 3 to 120 t/ch. For a single melting furnace, the natural gas consumption per ton of aluminum is 55 - 58 Nm³/t.Al. The natural gas consumption per ton of aluminum for the upper and lower furnaces can be controlled within 70 Nm³/t.Al. The NOx emission is < 180 mg/m³ at 9% O₂. The newly launched patented technology, the top - mounted multi - point regenerative combustion system, combined with the internal and external circulation technology of molten aluminum, has higher thermal efficiency and better quality of molten aluminum. Compared with the traditional side - mounted burner, the service life of refractories is increased more than 30% and the burning loss is reduced more than 1%.
