氟盐连续铸轧法生产Al-Ti-B中间合金的研究

Research on the Continuous Casting of Al-Ti-B Intermediate Alloy by Fluoride Salt

Al-Ti-B中间合金是一种高效实用的铝合金晶粒细化剂。对氟盐连续铸轧法生产Al-Ti-B中间合金的工艺过程进行了总结、分析,着重研究了氟盐的加入顺序、熔体的过热温度、搅拌及静置时间、轧制和稀土对中间合金的性能的影响,并提出生产中应注意的环节及改进方法。随着高性能Al-Ti-B中间合金的出现,Al-Ti-B在细化剂市场上的主导地位将不断巩固。

Al-Ti-B intermediate alloy is a kind of aluminum alloy grain refiner efficient. The process of fluoridesalt continuous casting method to produce Al-Ti-B intermediate alloy are summarized and analysed, the influence of thefluoride addition order, melt superheat temperature, mixing and settling time, rolling and rare earth on the perform-ance of the intermediate alloy are studied. And the attentions should pay to during the production link and improvement method are pointed out. With the advent of high performance Al-Ti-B intermediate alloy, Al-Ti-B dominance inthe refining agent on the market will continue to consolidate.
