Aluminum casting has the advantages of low cost, good technology, remelting and saving resources and energy, so the application and development of this material will be endless. For example, the research and development of EAF duplex smelting process and equipment; the extensive use of advanced hot metal desulfurization and filtration technology; thin-walled high-strength cast iron manufacturing technology; cast iron composite manufacturing technology; cast iron surface or local strengthening technology; isothermal nodular cast iron shell technology; the use of metal mold casting, metal mold sand covered casting, continuous casting and other special processes and equipment.
Products produced by aluminum casting manufacturers are widely used, involving a considerable number of product areas and industrial categories. In these applications, the quantity, variety, requirement, quality and quantity of metal materials should be considered comprehensively to promote the development of automobile industry. Due to a series of excellent properties such as low density, high specific strength and corrosion resistance, cast light alloy cast aluminum will be widely used in aviation, aerospace, automobile, machinery and other industries. In order to reduce the oil consumption and improve the utilization rate of oil source, it is a long-term development trend to replace steel and iron castings with aluminum and nickel alloy castings. It mainly solves the problems of refining technology, modification technology, grain refinement technology and rapid detection technology. In order to further improve the properties of materials and give full play to the potential of materials, aluminum alloy materials, especially aluminum matrix composite materials, can be developed to meet the performance requirements under different working conditions.
(1) When pouring aluminum castings, the coarse sprue is easy to produce inclusions, so for large aluminum castings, one or two groups of sprue can be used for pouring, each group of sprue is composed of several finer sprues.
(2) For large-scale aluminum castings with more diaphragms, it is very important to avoid casting defects and discharge the casting itself.
(3) When semi metal casting and top pouring process is adopted, in the case of inconvenient riser setting, the aluminum casting manufacturer can set funnel-shaped gate in key parts, the gate liquid level keeps dropping, and it can be re poured for many times to achieve full pouring effect.
