AI Technical Summary

Technical Problem

The existing aluminum square bar casting process uses fixed casting parameters, which cannot adapt to the dynamic fluctuations in the properties of molten aluminum, resulting in a decline in the quality of the aluminum square bars.

Method used

By employing customized intermediate alloys and refining processes, combined with intelligent degassing equipment and temperature and speed control, the purification and forming process of molten aluminum is optimized, including smelting, refining, crystallizer forming, and subsequent processing.

Benefits of technology

The quality of aluminum square bars has been improved by homogenizing the composition, removing impurities, and controlling the cooling and solidification process, thus ensuring the uniformity of the microstructure and the stability of the performance of the aluminum square bars.

Abstract

本发明涉及铝方棒铸造技术领域,尤其涉及一种用于电解铝阳极导杆的铝方棒铸造工艺,解决了现有技术中存在铸造参数固定,无法适配铝液特性动态波动,最终导致降低了铝方棒质量的问题,本发明通过先选用纯度不低于99.70%的铝合金基材搭配定制化中间合金,经碱洗酸洗预处理后按指定重量备料,随后将原料熔炼并精准调控成分,经电磁搅拌均匀后用无钠精炼剂处理,刮渣铺覆覆盖剂后氩气除气静置提升纯净度,再让铝液流经密封流槽预热回收、除气过滤后送入结晶器,控制牵引速度与冷却水量并喂钛硼丝优化晶粒成型,最后对坯料锯切矫直、酸洗打磨并经多道检测,最终得到合格的电解铝阳极导杆用铝方棒。
