In addition to the plant's ingot analysis of main components and impurities, but still low accompany organizational checks and fracture. Practice has proved that the use of containing serious shrinkage, pinhole, and the bubble of molten aluminum, it is difficult to obtain dense castings, and even cause the entire furnace, casting the entire batch of scrap. Some people in the study of the influence of Al-Si alloy ingot aluminum pinhole found no pinholes when casting molten pure sand test block, when added to low tissue and substandard aluminum-silicon alloy ingots, pinhole test block severe, and large grains. The reason for this is due to the genetic material. When the Al-Si based alloy and genetic improvement of surface increases as the content, silicon content of 7% Henan motorcycle recovery, genetic significantly. Continue to increase the silicon content to the eutectic composition, hereditary and slightly reduced. To solve the casting defects caused by hereditary charge, we must use high metallurgical quality of aluminum ingots, master alloys and other charge. 2012 national plan new towns of affordable housing projects started seven million units or more, basically completed 5 million units, according to the current standard of decoration, aluminum consumed more per square meter, about 1.4-1.5 kg to calculate Shandong motorcycle recovery, will aluminum alloy 2012. The increase in demand 35-37.5 million tons. In addition, China's current urbanization rate is only 46% of Hunan motorcycle recovery, the development of urbanization will effectively increase demand for aluminum. With energy-saving cars, to reduce the weight of the demands of car will gradually replace steel with aluminum in the future, automotive aluminum will have a huge market, mainly for the automobile hood and doors. Aluminum wheels are in the car the second widely used in the field of aluminum alloy. Because light weight, good heat dissipation and has a good appearance, alloy wheels gradually replaced the steel wheels.
