① smelting and recovery: the current furnace 5% aluminum smelting furnace, oil furnace 91% aluminum box, gas furnace 4%, forming a remelting 1 ton of kneading ingot fuel consumption higher than the industrialized countries 55.17% , While the energy consumption of the practice ingot (rolling ingot and kneading ingot) is much higher than that of industrialized countries. In addition, the overall energy consumption of aluminum smelting furnace is still at a low level. The company is located in:
② casting, rolling and kneading: the lack of high-grade goods; small machines and more kneading equipped with more backward Anji aluminum boxes, low power; equipped with a low degree of automation can not be completed quickly isothermal kneading, producing fine profiles; mold Poor quality. The company is located in:
③ surface treatment: surface treatment is aluminum processing process of high power consumption, high water consumption, high pollution links.
