高品质轴承钢LF--VD过程非金属夹杂物演变规律OA北大核心CSCDCSTPCD
Evolution rules of inclusions in high quality bearing steel produced by LF--VD process
对国内一钢厂EAF→LF→VD→CC工艺生产的高品质GCr15轴承钢进行系统取样,针对DS类非金属夹杂物随机性强的特点,利用能够进行大面积试样检测的ASPEX自动扫描电镜分析统计钢中非金属夹杂物的成分、尺寸、数量等信息。研究发现：GCr15轴承钢冶炼过程中非金属夹杂物主要为MgO- Al2 O3- CaO复合夹杂物和MnS,同时有少量的SiO2- Al2 O3和MgO-Al2 O3复合夹杂物；夹杂物尺寸主要集中在3~8μm,并有少量DS类夹杂物出…查看全部>>
High quality GCr15 steel produced by EAF-LF-VD-CC process was systematically studied by sampling in various sta-ges for a domestic factory. For the random characteristics of DS inclusions, the evolution rules of inclusions in bearing steel smelting process were investigated by ASPEX inclusion quick analysis equipment, which can scan the specimen surface in large enough area. The results indicate that the main inclusions are MgO-Al2 O3-CaO and MnS, and there …查看全部>>
