前言因铝合金熔点低,易熔化,所以象熔体除气等重要问题,一般不太被重视,认为只要用氯气或其他较简便的操作进行处理便可以了.但是,随着对产品质量的要求日益提高,近年来,从节能和防止公害的角度来看,铝合金熔炼便成为一个值得注意的问题,对此,已开始进行新的尝试并设法改进精炼方法. Preface Due to the low melting point of aluminum alloy, easy to melt, so as the melt out of gas and other important issues, generally less valued, as long as the use of chlorine or other relatively simple operation to handle it.However, as the quality of the product In recent years, aluminum melting has become a notable problem in terms of energy saving and pollution prevention, and new attempts have been made to improve the refining method.
