The establishment of modern renewable resource recycling system is to improve resource utilization, achieve the objective requirements of sustainable economic development and realistic choice. According to China's 12th Five-Year Master Plan, even for a long time in the future, our country should the transformation of economic growth mode as the main line, the currently high level of economic development, maintain an average annual growth rate slow, resource shortage is the biggest constraint One of the factors. Vigorously develop and use of renewable resources is the foundation and an important way to the development of circular economy. With the rapid economic and social development, a growing number of waste materials, and native resources are dwindling, renewable resources, recycling role in promoting economic development will show highlights. It can be said, renewable resources industry is a sunrise industry in the twenty-first century, a large number of energy saving, reduction of pollutant emissions and effective protection of the environment, especially in the mining costs rising resource prices gradually rise, the recycling of renewable resources It can greatly reduce the production cost Qingdao acquisition machine aluminum, saving resources and energy, reduce pollution, protect the ecological environment. 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 with molten pure sand casting test piece does not appear pinhole Qingdao acquisition machine aluminum, when added to low tissue and substandard aluminum-silicon alloy ingots, Qingdao pinhole serious test block acquisition machine aluminum, 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 of Qingdao acquisition machine aluminum, silicon content of 7%, the 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.
