MODELLING OF SINGLE-ROLL CONTINUOUS STRIP CASTING
摘要
A numerical model was developed to predict velocity field, temperature distribution and phase change occurring during single-roll continuous strip casting, when the ratio roll diameter to strip thickness is high. The thin-shear layer equations for mass, momentum and energy conservation are used as the governing equations, and they are coupled by the thermophysical properties and the solid/liquid interface. Their solution is performed by a control-volume based marching procedure with an adaptive grid. Simulations are presented for aluminum, and the solidification length from the nozzle exit is parametrically investigated as a function of roll speed, initial mean velocity, and heat transfer coefficient.
