针对U74重轨钢大方坯进行了开坯前后中心碳偏析的演变分析,并进一步分析了电磁搅拌参数和连铸工艺参数对铸坯中心碳偏析的影响,采用回归分析探讨了电磁搅拌强度和连铸工艺参数过热度与铸坯中心碳偏析的关系.
Based on the analysis of the evolution of carbon segregation before and after billet bloom in U74 heavy rail steel bloom, the influence of electromagnetic stirring parameters and continuous casting process parameters on carbon segregation at the center of billet was analyzed. Relationship between Superheat Degree of Casting Process Parameters and Carbon Segregation at the Center of.
