摘要
研究了Al-5Ti-1B晶粒细化剂添加方式和添加量对3102合金铝箔铸轧坯料晶粒大小的影响。结果表明:当Ti含量(质量分数,下同)为0.03%~0.06%,其中以丝状形式加入量在0,01%以上,其余以块状形式加入时,可得到晶粒尺寸在0.1mm以下、晶粒大小分布均匀的3102铸轧坯料。另外还分析和论述了控制3102铸轧坯料晶粒粗大应采取的操作技术措施和最佳工艺参数。
Effects of adding ways and addition of Al-5Ti-B master alloy on grain size of 3102 aluminum foils in casting-rolling process are investigated. The results show that the 3102 aluminum alloy billets with uniformly distributed grain below 0.1mm in size can be prepared by adding Ti content of 0.03%~ 0.06% , where silk-like Ti addition is over 0.01%, the other is bulky. The operation and optimized processing parameters of controlling coarse grain in 3102 aluminum billet are approached.
