铝合金熔炼铸造能源与资源节约

Energy and resources conservation in melting and casting of aluminum alloy

在铝材生产中,熔炼、铸造工序是能源与资源消耗多的工序,因此,节约资源、降低烧损与能耗有着重要意义。降低能耗还可以相应地减少温室气体与有害、有毒物质排放,对环保有利。中国当前铝合金熔炼铸造能源与资源节约的主要措施:调整加工用锭坯供应结构,大幅提高电解铝厂供应的锭坯,由2013年供应的42%提高到"十三五"末的65%-70%;加快走出去的力度,到国外去办铝厂,将在国外生产的铝合金锭坯运回来,争取2020年出口的铝材与铝制品全部以进口锭坯加工,这是最大的资源与能源节约;加强废铝回收与有效再生利用;加强创新,大力采用新装备、新技术与新工艺;加强管理,精心操作,管理中还有较大的能源与资源节约潜力。

Melting and casting consume most energy in the process of aluminum production,where saving energy and reducing melting loss really make sense. Besides,energy saving can also reduce the emission of greenhouse gases,harmful and noxious substances,so as to make the environment better. Currently,China is taking major measures to save energy and resources in the process of aluminum melting and casting. We seek to reorganize the supply mix of ingots for processing,by way of increasing ingots supplied by electrolytic aluminum manufacturers from 42% in 2013 to 65%- 70% at the end of ＂the thirteenth fiveyear development＂. We speed up efforts to establish aluminum plants overseas,so as to bring aluminum ingots produced abroad back to China,in which way we are striving to produce aluminum materials and products for export with nothing more than imported aluminum alloy ingots in 2020. This is the greatest degree of resources and energy saving Meanwhile,we are improving recovery and recycling of aluminum scraps,advancing innovation by developing new equipments,creative technique and upgraded processes,and reinforcing management of operation,where energy can be conserved more effectively.
