在铝铸轧过程中使用Al-Ti-B丝应注意的几个问题

Pay Attention to Some Problem in Using Al-Ti-B Refiner during Aluminium Continuous Cast-rolling Process

试验对比研究了在铝铸轧过程中,添加进口Al-Ti-B丝、国产Al-Ti-B丝和未添加Al-Ti-B丝细化剂对产品性能的影响,以及Al-5Ti-1B丝中金属间化合物尺寸、弥散度,以及Al-Ti-B丝中Ti、B含量比值,Ti、B含量,Al-Ti-B丝添加量、添加方式等对细化铝晶粒效果的影响。

The Al-Ti-B refiner selection during the aluminium continuous cast rolling process was introduced.The effects of the size and dispersivity of intermetallic compounds in Al-Ti-B refiner as well as Ti/B ratio,Ti?B content in Al-Ti-B refiner on aluminium grain refining were studied.The Al-Ti-B refiner additive amount,and additive way also were studied.
