ジャーナル フリーA study is made on the addition of elements to promote the white solidification of cast iron for the purpose of spectrographic analysis.
The results obtained are summarized as follows:
(1) Even if a thin plate sample is made by casting the melt in a copper mold, it is impossible to restrain the graphitization for samples having the saturation degree of carbon above 1.1.
(2) Little effect is observed when 1 to 5 per cent of tin is added to increase the chilling tendency and hence to improve the analytical precision.
(3) Addition of 1 per cent of chromium or tellurium ensures the white solidification of almost all samples whose saturation degrees are less than 1.3, and besides analytical precision and accuracy are improved for silicon and manganese by using these auxiliary elements.抄録全体を表示PDF形式でダウンロード (8534K)
