| 摘 要： | 针对RH工艺生产轴承钢,通过现场试验研究了RH真空处理时间对钢中全氧和显微夹杂物的影响.试验结果表明,延长RH真空时间可以进一步降低钢中全氧和显微夹杂物的数量,RH脱氧主要是通过显微夹杂物的去除,全氧与显微夹杂物随时间的变化关系基本一致;真空处理25min可使钢液中全氧和显微夹杂降低约60%,比14min时多降低约13%,并得出邢钢轴承钢生产条件下,RH精炼过程钢液的表观脱氧速度系数为-0.036min-1;工艺优化后147炉轴承钢产品的平均全氧为6.7×10-6.

| Abstract: | The influence of RH vacuum processing time on the total oxygen content and micro inclusion removal of bearing steel GCr15 was discussed. The results show that total oxygen content and micro inclusion amount will be decreased further by prolonging vacuum processing time,deoxidization during the RH process is caused by micro inclusion removal,and the relationship between the total oxygen content and RH vacuum processing time is in agreement with the relationship between the micro inclusion amount and vacuum p... |
