Abstract:
A method of monitoring surface temperature of at least one casting roll of a thin strip casting process, the method comprising the steps of:determining an inlet temperature (TI) and an outlet temperature (TO) of cooling liquid circulated through a cooling system of the at least one casting roll; computing a heat flux value (Q) as a function of the inlet and outlet temperatures, the heat flux value indicative of an amount of heat removed from the at least one casting roll by the cooling system; developing a correlation between the surface temperature of the at least one casting roll (TROLL), the heat flux value and the outlet temperature; mapping a first threshold surface temperature to a first threshold outlet temperature using the correlation; monitoring the outlet temperature; and generating a signal if the outlet temperature exceeds the first threshold outlet temperature, the signal thereby indicative of the surface temperature of the at least one casting roll exceeding the first threshold surface temperature.
