Abstract

A model has been derived for empirical evaluation and predictive analysis of the effect of temperature on the sinter production rate. The established model; ã=32.095-0.0067á showed that the sinter production rate was dependent on the sintering temperature within the range (864-11000C). The validity of the model was rooted in the expression 32.095-y =0.0067á, where both sides of the expression were approximately almost equal. The model-predicted and experimental data proximately agreed that beyond a temperature of 9630C, the sinter production rate decreased with increase in the operation temperature. Sinter production rates per unit rise in the operation temperature as obtained from experiment and derived model were evaluated as -0.0064 and -0.0067m2/h respectively. The maximum deviation of mode-predicted data from the corresponding experimental values was less than 15%, which is quite within the acceptable deviation limit of experimental results.
