Generally renewable resources are those through the use, consumption, processing, combustion, after discarding the program, still in a certain period (predictable) formed in the repeat, and has self-renewal and self-healing features being the sustainable use a class of natural resources or natural resources. And non-renewable resources corresponds in the construction of sustainable development should be strengthened to promote the use of green resources. Such as: soil, solar, wind, water, plants, animals, microorganisms, geothermal, tidal energy, biogas and natural biological communities, forests, wetlands, grasslands, aquatic organisms and other renewable natural resources at this stage given the nature of space-time conditions, can continue to regenerate update, multiply growth, to maintain or expand its reserves, relying on provenance and regeneration. Renewable energy refers to the energy used by a variety of recycling, rigorous, it is a human lifetime would not run out of energy. Renewable energy does not include current limited energy, such as fossil fuels and nuclear power. Not only the number of non-renewable resources are limited, aluminum, at a certain time with the space scale, the number of renewable resources are limited. In other words, renewable resources are not "inexhaustible" resources, it is a dynamic concept. Aluminum and aluminum alloys can be used a variety of methods smelting. Often using a coreless induction furnace and trough induction furnace, crucible furnace and open hearth furnace reflective (use natural gas or fuel oil combustion) and resistance furnaces and electric radiant. Charge a wide range, from high-quality pre-alloyed ingot until special charge constituted by the low-level waste can be used. However, aluminum ball, even in the most suitable conditions for melting and pouring of molten aluminum also vulnerable to the adverse effects of three types: - at high temperatures, copper and aluminum wire, with the passage of time, the aluminum price, hydrogen absorption leads to an increase in the melt was dissolved hydrogen. ? In high temperature conditions, as time goes on to ask, melt oxidation. · Loss of alloying elements.
