China Aluminum Industry Net. 1. Energy-saving and environmental protection trends in melting furnaces are becoming increasingly important. Modern melting furnaces now use advanced furnace designs and improved refractory materials to enhance insulation, increase thermal efficiency, and make better use of waste heat, thereby reducing overall energy consumption. For example, regenerative automatic control combustion systems, magnetic stirring, and split furnace doors are being implemented. Electrolytic aluminum liquid is directly used as raw material, and desulfurization and dust removal technologies help lower emissions. Energy conservation and environmental protection are now essential directions for the casting industry's development.
2. The trend toward purer molten metal is also gaining momentum. The quality of the ingot largely depends on the purity of the melt—low gas content, minimal slag, and reduced impurities are crucial. Grain refinement techniques are being improved to ensure better microstructure. Tilt-type holding furnaces help minimize the impact and turbulence of molten aluminum, reducing secondary pollution. Purification systems such as permeable bricks or rotating rotors are widely used, along with online purification systems that offer stable and effective performance.
3. In casting mold technology, low-level crystallizers and automated control systems are becoming more common. The use of automatic lubrication or graphite plates (rings) in gas-slip crystallizers significantly improves the surface quality of ingots, especially for high-magnesium aluminum alloys. This leads to better straightness, thinner shells, and less machining required during operations like sawing, trimming, and milling, thus increasing casting yield. Pulsed water technology controlled automatically is applied in hollow ingot casting, solving issues like "core squeezing" and reducing cracks at the bottom of hard alloy ingots.
4. Reducing production costs is another key trend. Optimizing the production process increases efficiency and minimizes metal loss. Techniques like rapid melting and isothermal smelting help reduce metal burning. Some aluminum alloys can now be produced using electrolytic aluminum as a raw material. Companies involved in aluminum processing can also cut costs by purchasing ingots and casting them into coils for hot and cold rolling, making the entire process more cost-effective.
5. Enhancing casting technology is a major focus, with developments in large-scale ultra-high-strength alloy casting, electromagnetic casting, and intelligent casting. Composite casting methods are being adopted, not only saving energy but also boosting productivity and yield. These innovations are driving the industry toward more efficient, sustainable, and high-quality production processes.
