Numerical model of aluminothermic reduction vessel preheating and charge heating with graphite heating rods

The model predicts that available electrical equipment is sufficient for preheating the empty reduction vessel up to 1600°C in less than 4 h. Owing to the model, the geometry of the heating rod was optimized to maintain its temperature below 2500°C. However, it was found that a modification of the electrical equipment would be required to heat the vessel charge with the heating rods submerged into it.
