GCr15轴承钢低氧控制研究

Research and development of european standard steel EA1N for railway vehicles axle

氧含量是衡量GCr15轴承钢洁净度的主要指标,本文分别对影响钢中氧含量的因素进行研究,分析铝氧反应的热力学条件,通过控制铝含量、精炼渣碱度与A值,获得高纯净度的轴承钢。

Oxygen content is the main index to measure the cleanliness of GCr15 bearing steel.This paper studies the factors affecting the oxygen content in steel,analyzes the thermodynamic conditions of aluminum oxygen reaction,and obtains high purity bearing steel by controlling aluminum content,alkalinity of refining slag and A value.
