- 摘要:
- 铝钛硼作为最常用的铝合金细化剂之一,在现场使用过程中存在细化能力无法完全发挥的问题。研究铝钛硼添加时间对铝钛硼吸收率及对组织细化效果的影响。结果表明,添加时间与吸收率和组织细化效果均呈反比关系;延迟添加铝钛硼合金的时间节点,B元素的吸收率和细化效果逐渐提高;浇包内铝-钛-硼添加的较佳时间为开始除气8 min时添加。
Al-Ti-B is one of the most commonly used refining agents for aluminum alloys.In the process of field use,there was a problem that the refining ability cannot be fully developed.The effects of Al-Ti-B addition time on Al-Ti-B absorptivity and microstructure refinement were studied.The results show that the addition time is inversely related to the absorptivity and the effect of microstructure refinement.The absorptivity and refining effect of element B are gradually improved when the time node of adding Al-Ti-B alloy is delayed.The proper time to add Al-Ti-B in the casting ladle is 8 min after the start of degassing.
