摘要
A model-based strategy is provided for determining casting roll operating temperature in a continuous thin strip casting process. A first temperature sensor produces a first temperature signal indicative of the temperature of cooling liquid supplied to the casting rolls and a second temperature sensor produces a second temperature signal indicative of the temperature of cooling liquid temperature exiting the casting rolls. A computer determines a heat flux value as a function of the first and second temperature signals, and computes the operating temperature of the casting rolls as a function of the heat flux value, the second temperature signal and a number of constants defined by fixed-valued operating parameters of the continuous thin strip casting process. A control strategy is also provided to modify one or more operating parameters of the continuous thin strip casting process as a function of the casting roll temperature.
