Vessels And Horizontal Castings

Abstract
A mathematical model of micro morphology generation in solidification process
has been developed using cellular automaton approach, and heterogeneous
nucleations from the wall and the grain growth kinetics are simulated by using
the Monte-Carlo simulation. In the next place, the change in the micro
morphology from the dendritic to the equiaxial, has been analyzed in the same
way, under the condition that the liquid metal in the vessel is excited from
magnetic stirrer. The results are compared with those obtained by the
experiments on vessel casting, twin roll casting and horizontal continuous
casting, and the applicability of the method has been verified.
