The low cost and good processability of cast aluminum parts, as well as the ability to save resources and energy through remelting and regeneration, have been widely used and developed. The research and development of the electric furnace double melting process and equipment for the blast furnace adopt advanced iron desulfurization and filtration technology, thin walled high-strength cast iron manufacturing technology, cast iron composite material manufacturing technology, and surface or local strengthening technology for cast iron parts; The complete set of technology for warm ocean ductile iron adopts special processes and equipment such as metal mold casting, metal mold sand covered casting, and continuous casting.

        Due to its excellent properties such as low density, high specific strength, and corrosion resistance, cast aluminum lightweight alloys will be more widely used in various industries such as aviation, aerospace, automotive, and machinery. Especially in the automotive industry, replacing steel and iron castings with aluminum and nickel alloy castings to reduce fuel consumption and improve energy utilization is a long-term development trend. Among them, emphasis is placed on solving pollution-free, efficient, and easy to operate refining technology, metamorphic technology, grain refinement technology, and rapid detection technology before the furnace. To further improve material performance and maximize the potential of materials, high-quality aluminum alloy materials, especially aluminum based composite materials, can be developed to meet the performance requirements of different working conditions.
