. Meanwhile, the solute elements are focused gradually in the kern zone, and the maximum value is gotten at the Kiss point zone. In particular, Fe content of the Kiss point zone is much higher than...; solute field; flow field; centerline segregation; Kiss point 双辊薄带铸轧技术被认为是21世纪冶金行业最有发展潜力的技术之一,该工艺是将高温金属液浇入一对相对转动结晶辊间形成熔池,金属经过结晶辊冷却和轧制作用,直接加工为成品薄带.而芯部夹层和偏析问题是困扰双辊薄带铸轧技术发展的难题之 一[1].夹层和偏析不仅会使产品......
Kiss point附近区域.Vortex 2不仅影响熔池固液两相区所占比例,而且能使偏聚在Kiss point附近富溶质铝液返回到熔池进行混合再分配.涡流的存在不仅可以促使富含溶质的铝液返回到熔池中进行再混合均匀化,另一方面该涡流的存在还能够以较大的速度冲击枝晶臂,以及芯部较高的温度能熔断枝晶,这两方面都有利于增加形核率,促使Kiss点区域温度场均匀化从而有助于芯部等轴晶的形成[12]. 图2... by the casting and rolling experiments of the aluminum alloy 6061. Key words: twin-roll strip casting; centerline segregation; flow field; Kiss point height Foundation item: Project(51374184) supported......
force for strip casting of 1Cr17 ferritic stainless steel was predicted using theoretical model and artificial intelligence. Solution zone was classified into two parts by kiss point position during... to build model for kiss point position. The results show that calculation accuracy for verification data of 94.67% is in the range of ±7.0%, which indicates that the predicting accuracy of this model......
to predict the rolling force in the bimetal solid-liquid cast-rolling bonding (SLCRB) process. The solid-liquid bonding zone was assumed to be below the kiss point (KP). The deformation resistance... is of great significance to the stability of cast-rolling forming. Key words: bimetal clad strip; solid-liquid cast-rolling bonding; rolling force calculation model; kiss point; thermal-flow coupled......
