Abstract
In consideration of the collisions between particles and impingement of particles on wall, a mathematical model for calculation of slag accumulation for submerged nozzle in SRM was established and simulation was carried for a large scale motor. The results show that the model presented is reliable and accurate; the impingement and adherence of large particles, resulting from particle collisions, on walls is the main contributor to slag accumulation; and the local structure of grain near the inlet of submerged nozzle has an effect on slag accumulation process.
