    摘要
  • 摘要: 對高碳鉻軸承鋼連鑄坯白亮帶和中心碳偏析的形成機理及其影響因素進行了系統的分析研究,提出了改善偏析的措施.同時進行了連鑄鋼與模鑄鋼內在質量和疲勞性能的對比試驗.結果表明,連鑄軸承鋼坯存在輕微的碳偏析(Wc/Wco=0.92~1.10),其材質的疲勞壽命達到了模鑄鋼的水平.

     

    Abstract: The mechanism of "white band" and central carbon segregation formation of high-carbon chromium bearing steel concasting billets have been discussed.Comparative tests of metallurgical quality and fatigue property between the concasting steel and ingot casting steel showed that the carbon segregation (wc/wco) in steel produced by concasting process was 0.92~1.10 and the fatigue life of the former steel was equal to that of the latter steel.
