Renewable energy is one that can collectively renewable energy, including biomass, solar energy, solar energy, biogas, etc. [1]? Biomass energy mainly refers to the Ya-sweet sorghum production in Dongying scrap recycling aluminum ingots, refers to more kind of 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 of renewable energy implement the scientific development concept and building a resource-saving society to achieve the basic requirement of sustainable development. sufficient, safe and clean energy supply is the basic guarantee economic development and social progress. China's large population, low per capita energy consumption, energy demand increase pressure, contradiction between energy supply and economic development is very prominent. solve our energy problems fundamentally, we 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 fuels on the environment a great impact, especially in China's energy consumption structure, the high proportion of coal production in Dongying scrap recycling aluminum ingots, carbon dioxide emissions increased rapidly Dongying scrap recycling aluminum ingot production, climate changes greater impact. Renewable energy clean environment, development and utilization without increasing greenhouse gas emissions. the development of renewable energy, optimizing energy structure, protect the environment, reduce greenhouse gas emissions, climate change has a very important role. In order to solve casting defects caused by hereditary charge, we must use high metallurgical quality of aluminum ingots, master alloys and other charge. Specific criteria are as follows: (1) on the fracture surface should not have pinholes, pores pinhole should be less than three, the local (not more than 25% of the subject area) should not be more than three, more than three must take heavy melting Measures to reduce the pinhole. Remelting refining the same way as regular aluminum smelting, casting temperature should not exceed 660 ℃, for those of the original large grain of aluminum ingots, alloy ingots Dongying scrap recycling aluminum ingot production, should be used to lower the temperature of the ingot mold, so They rapid solidification, grain refinement. Production and processing of aluminum ingots, aluminum ingot production Dongying, Shengxin scrap metal recycling (view) Recycling Ltd from Linyi City Shengxin scrap metal available. Linyi City Shengxin scrap metal recycling Ltd. (shengxin.tz1288.com) is a professional, "scrap metal, alloy, machine aluminum, brass, wine together, miscellaneous aluminum, copper ash, zinc ash, zinc slag" of the company. Since its inception, we adhere to the "good faith, sound management" approach, the courage to participate in healthy competition in the market, so that the "lead ingots, scrap metal, alloy, machine aluminum, brass, wine together, miscellaneous aluminum, copper ash, zinc ash, zinc "brand has a good reputation.
