摘　　要：通过对CrNiMo军工钢真空脱气的可行性研究,经真空脱气后,发现钢中气体和有害夹杂含量得以明显降低,因而大大减少了CrNiMo军工钢发生纵裂和轴心间裂纹的机率;提高了钢材的使用寿命。Through the CrNiMo military steel vacuum degassing of the feasibility study, the vacuum degassing, were found in the steel content of gases and harmful inclusions can be significantly reduced, thus greatly reducing the occurrence of CrNiMo military axis between crack and fracture risk ; increase the service life of steel.
