Abstract: This paper introduces the structure of mould liquid steel level control system in continuous casting and uses the fuzzy dual-mode control algorithm to control the liquid steel level. Prepared with the traditional method, the advanced control system is more efficiently to smooth away the change and disturbance during the producing. The experiment result shows that the method is valid.

Key words: Fuzzy dual-mode control, Fuzzy inference, Liquid steel level
