Analysis of Thermal Stress and Deformation of Casting Roll in Twin Roll Strip Casting Process

쌍롤형 박판주조공정에서 주조 롤의 열응력 및 열변형 해석

  • Published : 2002.09.01


The casting roll design is one of the most important requirements in twin roll strip casting process. Coupled analyses of heat transfer and deformation for the cast roll are carried out by use of the finite element program MARC to examine the thermal stress and deformation. The effects of several factors on thermal stress and deformation are also investigated. The amount of thermal stress increases when the ni thickness increases and when the casting speed and the copper sleeve thickness decrease.
