日本有用石英管吸引凝固法研究Al、Ti、Bi、Te、S等微量元素对铸铁凝固过程中生成氢气孔的影响,可以排除铸型的复杂影响,获得更单纯的实验条件,在氢被吸收的过程中不会产生氧化物,能测出临凝固前铁水中的氢含量。所谓石英管吸引凝固法,就是在控制H_2量的 In Japan, the influence of the trace elements such as Al, Ti, Bi, Te, S and so on on the formation of hydrogen pores in the solidification process of cast iron can be studied by Japan’s quartz tube suction solidification method. The complicated influence of the casting mold can be eliminated and pure experimental conditions can be obtained. The process does not produce oxides, can detect the hydrogen content of the hot metal just before solidification. The so-called quartz tube to attract solidification method, is to control the amount of H_2
