Internal (Convection) Cooling of CCM Rolls Under Scale Formation Conditions

详细

A procedure for the evaluation of the thermal conditions for the rolls of continuous casting machines operating in the conditions of scale formation in the cooling channel is proposed. The procedure allows a differentiated approach to the determination of the axisymmetric and maximum surface temperature of the rolls with allowance for the magnitude and behavior of the thermal load and the cooling and scale formation conditions on the heat-exchange surfaces. It can be used to predict the roll service life and to rate the quality of cooling water.
