Abstract
본 발명은 Bi(비스무트)를 합금원소로 하는 알루미늄 합금을 제조항에 있어 Bi를 효과적으로 첨가하는 방법에 관한 것으로서, 이는 대체적으로 저융점(271.4℃) 금속으로 액체상태에서도 알루미늄(Al)에 부분적으로만 용해가 되고, 또한 고체상태에서는 비중이 9.8 이나, 융점부근에서는 비중이 1이 되는 금속이기 때문에 합금화가 쉽게 이루어지지 않는 비금속 특성을 가지고 있는 비스무트(Bi)를 합금중에 투입함에 따른 종래기술의 문제점을 해소하고자 하는 것이다.The present invention relates to a method of effectively adding Bi in the production of an aluminum alloy containing Bi (bismuth) as an alloying element, which is a low melting point (271.4 ° C.) metal, partially in aluminum (Al) even in a liquid state. The problem of the prior art is that bismuth (Bi), which has a non-metallic property that is not easily alloyed because it is dissolved and has a specific gravity of 9.8 in the solid state but has a specific gravity of 1 in the vicinity of the melting point, is introduced. To solve the problem.
따라서 본 발명은 Bi 첨가를 선재형태로 투입하고 투입된 Bi를 용융 Al에 균일하게 교반하여 합금화를 촉진시켜주므로서 Al-Bi 모합금의 편설에 따른 불량율을 줄일 수 있으며, 또한 각 공정을 자동적으로 처리히므로서 작업성 내지는 생산성을 향상시킬 수가 있는 효과를 제공할 수가 있다.Therefore, in the present invention, the addition of Bi in the form of a wire rod and uniformly agitated Bi into molten Al promotes alloying, thereby reducing the defect rate according to the Al-Bi master alloy unevenness, and also automatically processes each process. By doing so, it is possible to provide an effect of improving workability or productivity.
