通过对各种处理剂处理的蠕虫状石墨铸铁凝固过程的研究，共晶反应时石墨的析出过程已经明确。

Solidification process of CV graphite iron with the addition of various CV-graphitizing materials and the crystallization behavior of the graphite during the eutectic reaction was clarified .

第二阶段形成蠕虫状石墨，因包围球状石墨的奥氏体部分熔解，使它与熔液接触生长。

The CV graphite was formed in the second stage and grew in contact with the liquid due to partial dissolution of the austenite shell surrounding the graphite spheroid .

在含硫0.030%的铁水中，锑量增至0.017%时，所得试样的蠕化率开始上升，尤其是在薄断面上更为显著，石墨形貌也开始出现与常态蠕虫状石墨相异的现象；

Increasing the Sb content to 0.017 % in a melt of 0.030 % S , the CG percentage begins to increase , especial in a thin section , and graphite morphology begins to change ;

结果表明，中硅蠕虫状石墨铸铁在很多性能方面优于铬钼铜合金铸铁，并已成功地应用于大马力柴油机活塞环上。

The result has shown that medium silicon content VG cast iron is superior to Cr-Mo-Cu alloy cast iron , and the material has been successfully applied to the piston ring of the greater horse-power diesel engine .

蠕虫状石墨能与片状石墨间相互连续生长过渡，认为蠕虫状石墨为一定变质元素含量及凝固速度条件下石墨晶体特有的组织形态，无须球化衰退或石墨球破碎为其生长前提。

The graphite of vermicular structure is a special one which is growing up under certain conditions of modifying element Ce and solidification rate with no need to decay the nodularization or to break the graphite nodules prior to its growth .
