如果答案满意另加500分,说到做到,诚信为主
铝元素在地壳中的含量居第三位，仅次于氧和硅，是地壳中含量最丰富的金属元素。在金属品种中，仅次于钢铁，为第二大类金属。随着有色金属技术的发展,铝及铝合金以它特有的优势被广泛应用于工业，农业，国防等各个行业，特别是近几年汽车行业高速发展，使得铝合金铸件的使用规模不断扩大及质量要求也越来越高，因此对铝合金熔化保温设备技术水平的要求也越来越高
铝合金保温炉是用于铝合金材料熔化后名铝水的保温静置。本文作者设计的铝合金保温炉，炉体带有一个保温室和两个取铝口及回铝口，分别进行铝水的静置保温和铝水的提取浇铸及回放。将熔化后的铝合金液体静置于保温室内，可以保证稳定不断地提供所需温度的铝液。本炉子具有热效率高、金属烧损低、金属液质量高、温度控制精确的特点，能连续提供铝液等特点

我来补答

Aluminum is the crust's third most abundant metal,only behind oxygen and silicon,.In the metal species,aluminium is he second largest category of metals,second to iron and steel,With the development of non-ferrous metals technology,aluminum and aluminum alloy are widely used in industry,agriculture,national defense and other industries for its unique advantages,Especially for the rapid development of automobile industry in recent years,the use of aluminum alloy casting components have been expanding and the quality requirements have become more and more higher,and therefore the technilogy requirements on aluminum melting insulation equipment have increasingly heightened.
Aluminum holding furnace is used for heat holding after the aluminum alloy melt into liquid aluminum .This aluminum holding furnace was designed with a heat chamber,two take-back ports and one aluminum filling port,respectively for liquid aluminium insulation & heat holding,pick up & casting and refulling.The molten aluminum alloy placed indoors which can provide the necessary liquid aluminium stability and continuly.The furnace has some characteristics; high thermal efficiency,low metal burning lose,high quality liquid metal and accurate temperature control,it can provide higt quailty liquid aluminum continuously.
