化学成分对TEMF法快速测定高炉生铁中硅含量的影响

Influences of Chemical Composition on Rapid TEMF Silicon-Determinating for Hot Metal

利用TEMF法（即热电动势法）测硅仪，测定了C，S，P和Mn元素等含量不同的高炉生铁样品的热电动势，研究了热电动势的变化，得出C，S，P的影响可忽略，Mn稍有影响的结论。

The thermal electromotive force, Et,of the pig iron samples with different C, S, P and Mn content is measured by means of TEMF silicon-determinating device. The variety of Et is studied and the conclusions are drawn that the influences of C,S,P on silicon-determinating can be neglected but the influences of Mn can not.
