With the rapid development of the recycled aluminum industry, the upgrading of scrap aluminum recycling processes has become the key for enterprises to enhance competitiveness. In the recycled aluminum smelting process, impurity removal, temperature control and the stability of furnace equipment directly determine the quality of aluminum ingots and production efficiency. Focusing on the characteristics of recycled aluminum smelting, Huitai Technology has launched special recycled aluminum melting furnaces and supporting process solutions to help enterprises achieve efficient, low-consumption and environmentally friendly recycled aluminum production.
Key control points include:
  1. Raw material pretreatment: Classify, remove impurities and dry scrap aluminum to reduce moisture, oil stains and impurities entering the furnace, and reduce oxidative burning loss and harmful gas emissions during smelting.
  2. Precise control of smelting temperature: Adopt an intelligent temperature control system to stably control the smelting temperature at 720-750℃, avoiding aluminum liquid oxidation caused by excessive temperature or insufficient separation of impurities caused by low temperature.
  3. Optimization of refining and degassing process: Equipped with special refining agents and rotary degassing devices to remove hydrogen and inclusions in the aluminum liquid, improve the purity of the aluminum liquid, and provide high-quality raw materials for the subsequent casting process.
  4. Optimization of furnace structure: The recycled aluminum melting furnace uses anti-corrosion lining materials to extend the service life of the furnace body, and optimizes the flow field inside the furnace to improve the melting speed of scrap aluminum and reduce energy consumption.
Huitai Technology's recycled aluminum melting furnace can adapt to different types of scrap aluminum raw materials, realizing efficient conversion from scrap aluminum to high-quality aluminum ingots, helping enterprises reduce production costs and improve product quality.
