Simulation of strip casting process by twin roll method. (2nd Report. Analyses of solidification and temperature for steel, and inelastic stresses).

Abstract

The simulation technique of solidification and temperature distribution developed and verified by experiment in the first report was applied to the process of strip casting of a steel. The effect of operating condition, such as casting speed, diameter of roll, depth of molten metal and roll gap, on the shape of solidified shell and the temperature were examined by numerical calculation. Mode of stresses in the shell under steady material flow was also evaluated by use of elastic-viscoplastic constitutive relation, and the comparison between the results and the stresses was carried out by simple elastic-plastic model.
