【摘要】 通过相关数据的统计分析,找出了化学成分、结晶器使用次数、保护渣碱度、钢板厚度、装炉方式、冷却强度等对钢板星裂的影响规律。分析星裂产生的原因是,Cu原子、硅酸盐类夹杂物富集在奥氏体晶界,降低晶界强度,诱发星裂。更多还原

【Abstract】 Through statistic and analysis of interrelat ed data the effect rules of chemical composition,using frequency of mould,basic capacity of protecting slag,plate thickness,charging mode and cooling strength,e tc on star-like crack of plate were found.Beneficating of copper atom and silic ate t ype inclusions on austenite grain boundary was main cause decreasing the grain boundary strength and bringing out the star-like cracks.更多还原
