In addition to the plant's ingot analysis of main components and impurities outside scrap recycling plant, is 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%, 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. Renewable energy is one that can collectively scrap recycling renewable energy market, including biomass, solar energy, solar energy, biogas, etc. [1]? Biomass energy mainly refers Ya-sweet sorghum, refers to a variety of take it inexhaustible energy, strictly speaking, is not exhausted within the period of human history Energy Renewable energy does not include current limited energy, such as fossil fuels and nuclear energy benefits: 1, the development and utilization of renewable energy sources is to implement the scientific development concept and building a resource-saving society to achieve sustainable development of the basic requirements of adequate, safe and clean energy supply for economic development and social progress of basic protection. China's large population, low per capita energy consumption, energy demand growth pressure contradictions of energy supply and economic development is very prominent solve China's energy problem fundamentally scrap recycling, continue to meet the needs of economic and social development, protection of the environment and achieve sustainable development, in addition to greatly improve energy efficiency, accelerate the development and utilization Renewable energy is an important strategic choice, but also to implement the scientific concept of development, the basic requirements of building a resource-saving society. 2, the development of renewable energy is to protect the environment, an important measure to address climate change. At present, China's environmental pollution problems highlighted, fragile ecosystems, a large number of mining and use of fossil energy and environmental impact of large expensive scrap recycling, particularly the high proportion of coal in China's energy consumption structure, rapid growth in carbon dioxide emissions, renewable energy, clean environment greater impact on climate change. , development and utilization without increasing greenhouse gas emissions development and utilization of renewable energy, optimizing energy structure, protecting the environment, reducing greenhouse gas emissions, climate change plays an important role in the scrap recycling plant |..
