摘　　要：用半连续铸造法生产6063铝合金棒材,晶粒度控制较为严格,确保产量的前提下,通过调节铝液熔炼或静置温度提高成品晶粒度合格率受到客观条件的制约。为了得到更好的晶粒细化效果,采用炉前进给铝钛硼杆的方法,总结某生产厂试用炉前细化方法前后,6063铝合金准152棒材晶粒度等级数据,得出保证理想晶粒度细化结果的合理铝钛硼杆添加量,可以为同行提供参考。The grain size is strictly controled in the production of 6063 wrought aluminium alloy bars with the method of semi-continuous casting, increasing the grain size of finished ingot is objectively restricted just by adjusting the temperature of alumina liquid refining or quiescence. A good result has been required by bath feeding Al-Ti-B bars. The grain size rank data of 6063 wrought aluminium alloy bars of φ152 mm befor and after bath feeding Al-Ti-B bar test were generalized,and the appropriate addition of bath feeding Al-Ti-B bars was obtained to ensure ideal grain refinement result.
