铜包铝复合棒充芯连铸设备的开发

为了实现以铝代铜,开发铜铝复合材料,设计和制造了一台制备铜包铝复合棒坯的充芯连铸试验机.该机器的特点为:结晶器为水冷铜套内衬石墨套;在高度方向上设置一高一低直径不同的加热器,下加热器与结晶器相连接在此试验机上;充芯与连铸同时进行.利用该设备,成功地连铸出芯部直径为φ24mm,外层厚度为8mm的铜包铝双金属复合棒.

Continuous core-filling cast equipment for the bimetal composite materials of copper cladding aluminum

In order to develop copper-aluminum composite materials, a new equipment of continuous core filling cast for the bimetal composite materials of copper cladding aluminum was designed and produced, The characteristics of the new equipment were that, the crystallizer was composed of water jacket copper sleeve in which graphite sleeve was set; two melting furnaces with different diameters were vertically distributed, and the low furnace of melting copper was linked the crystallizer; and continuous casting and core filling were proceeded at the meantime. The bimetal composite of copper cladding aluminum was made successfully with the diameter of aluminum of Ф24 mm and the thickness of copper of 8 mm.
