WebDec 1, 2024 · It is shown that, at a constant melt rate, the shrinkage cavity has no effect on the ESR process as its radius is less than 0.025 m, and only a small influence on the slag flow when the radius reaches 0.05 m. As the radius increases over 0.05 m, an increasingly evident influence on the slag zone appears via the weakened center downward flow and ...
