【Abstract】 In this paper, it is pointed out that mathematical models for continuous casting or casting ingot, which have been published so far, are obtained from phase transforming with single element system, but melting or solidifying in iron- and steel making is really phase trans forming with several elements system. As a starting point from this, a new mathematieal model for continuous casting is established, as well as, its corresponding algorithms are presented to apply to numerical simulation and automatic control in industrial process.更多还原
