摘要/Abstract

摘要： 塞棒结瘤是限制轴承钢连铸稳定性的关键因素。以GCr15轴承钢连铸用后铝碳塞棒为研究对象,通过XRF和SEM对用后塞棒结瘤层进行了分析。结果表明:用后铝碳塞棒结瘤层平均厚度为2.61 mm,结瘤物组成主要为氧化铝、氧化钙和氧化镁。塞棒脱碳层与钢中夹杂物作用形成了硅铝酸钙、铝镁酸钙和尖晶石的变质层,变质层为多孔结构。塞棒表面的硅酸锆分解形成的氧化锆层能够阻碍钢液向脱碳层中渗透,氧化锆上层的结瘤层主要为铝镁酸钙、尖晶石、铝酸钙和钢,呈交错分布,其中铝镁酸钙呈多孔聚集体,铝酸钙呈圆球状。结合对塞棒结瘤形成机制的系统分析,针对性地提出了减少塞棒结瘤的措施。

Abstract: Stopper rod clogging represents the primary constraint on operational stability during bearing steel continuous casting.This study focuses on post-service Al₂O₃-C stopper rods from GCr15 bearing steel continuous casting.The clogging layers were analyzed using XRF and SEM techniques,revealing an average clogging thickness of 2.61 mm,with Al₂O₃,CaO,and MgO as primary constituents.The interaction between the decarbonized layer of the stopper rod and non-metallic inclusions in molten steel generates a metamorphic layer composed of calcium aluminosilicate,calcium magnesium aluminate,and spinel,characterized by a porous microstructure.The zirconia layer formed through thermal dissociation of zirconium silicate effectively impedes molten steel infiltration into the decarbonized layer.The overlying Nodules deposits on zirconia predominantly exhibit an interpenetrating microstructure of calcium magnesium aluminate,spinel,calcium aluminate,and steel matrix,where calcium magnesium aluminate manifests as porous agglomerates while calcium aluminate demonstrates spheroidal morphology.Based on systematic analysis of clogging formation mechanisms in stopper rods,targeted countermeasures were formulated to mitigate clogging phenomena.
