影响热型连铸制备纯铝线材的工艺因素研究

Investigation of processing foctors influencing heated-mo ld continuous castin of pure aluminum wire rod

在自制的水平式热型连铸设备上进行了工艺实验 ,结果发现 ,铸型温度、连铸速度、冷却距离对液固界面的位置有着显著影响 .要想得到成功的热型连铸铸锭 ,铸型温度。

Pure aluminum wire of 5 mm in diameter is p ro duced with the self made horizontal heated mold continuous casting equipment. The influence of processing factor such as mould temperature, casting speed, and cooling distance on the position of solidification front is discussed. It is es tablished that processing factors have a remarkable effect on the position of th e solidification front. In order to get a good ingot, the mould temperature must be kept above the melting temperature of the cast metal and processing factors must be match each other very well.
