覆层金属具有单一金属所不具备的许多优异的物理、化学和力学性能，因此在许多领域得到了广泛的应用。制造熔覆层的传统工艺有很多种，如辊焊、扩散焊、爆炸焊接、挤压熔覆和铸造熔覆。其中，连铸具有生产效率高、生产成本低、界面结合良好等优点，是制备熔覆金属的理想工艺。该工艺可以通过一液一液、一液一固或一液一半固态的方式使两种金属直接接触，从而获得良好的冶金结合。因此，这一过程受到了从事材料加工的研究人员的广泛研究。研究了直接水冷连铸生产3003/4004铝合金覆层圆锭的工艺。3003铝合金耐腐蚀性好，强度低，熔点高；4004铝合金耐腐蚀性差，强度高，熔点低。3003/4004铝合金覆层材料结合了两种金属的优点，可以广泛应用于许多领域，特别是在汽车发动机和空调散热器上。为了获得良好的界面结合，在该工艺中采用了具有单面冷却能力的特殊内模。通过特殊的内模，两种合金可以使一种液体-一种固体或一种液体-一种接触。
Cladding metals have been widely applied to many fields because they have many excellent physical, chemical and mechanical properties that can not be obtained from the single metals. There are many conventional processes for manufacturing cladding metals, for example roll bonding, diffusion bonding, explosive welding, extrusion cladding and casting cladding. Among these processes, continuous casting is an ideal process to prepare cladding metals which has the advantages of high production efficiency, low production cost and good interface bonding. This process can make two metals contact directly by the ways of one liquid-one liquid, one liquid-one solid or one liquid-one semi- solid and then the good metallurgical bonding can be obtained. So, this process is extensively studied by researchers engaging in material processing. The process of the direct water-cooled continuous casting to fabricate cladding 3003/4004 aluminum alloy circular ingot is researched in this paper. The 3003 aluminum alloy has excellent corrosion resistance, low strength and high melting point, while the 4004 aluminum alloy has poor corrosion resistance, high strength and low melting point. The cladding 3003/4004 aluminum alloy material can combine the advantages of two metals and can be widely used in many fields, especially in car engine and air conditioning heat sink. To obtain the good interface bonding, a special inner mold with the single-side cooling capability was applied in this process. By the special inner mold, the two alloys can make the contact of one liquid-one solid or one liquid-one
