矽、铝、锰都是常用的脱氧剂,对于它们脱氧产物的组成,可以用实际检定法及热力学数据来考查,二者并可互作参考。实际检定方法的缺点是只能检定骤然冷却后的固体试样,从而推测其在液体中的存在形态;而用热力学数据来考查时,往往因为高温实验困难,数据散乱,而得出各种不同的结果。因此对矽、铝、锰脱氧产物组成的问题,至今还存在着不同的看法。本文目的为重新分析文献上已有的脱氧数据来对脱氧产物的组成作一考查。
Silicon, aluminum and manganese are commonly used deoxidizers. For the composition of their deoxidation products, they can be examined by the actual verification method and thermodynamic data, and the two can be used as reference for each other. The disadvantage of the actual verification method is that only the solid sample after the sudden cooling can be tested to speculate the existence form in the liquid. When the thermodynamic data is used for the examination, often due to high temperature experimental difficulties, the data are scattered, the result of. Therefore, the composition of silicon, aluminum, manganese deoxidation products, there are still different views. The purpose of this paper is to re-analyze the literature on the existing deoxy data to make a test of the composition of deoxy products.
