Mathematical modelling of batch melting process in cold-top electric furnace

Abstract

One dimensional heat transport model is formulated to solve melting rate of batch as well as unsteady temperature distribution in thickness direction of batch. Heat exchange of batch with decomposed gas, volumetric change of batch during melting and tide of foam are considered. Numerical simulation is performed to demonstrate the temperature distribution during both heating and melting period. The simulation also presents steady melting rate for foam thickness and response of the rate for tide of foam. The calculated result provides time-temperature history to estimate reaction path of batch and characteristics of rough melt.
