Recovery Rates (%)
Calculation Formulas
Si Deficit = (Target Si - Scrap Si) × Total Metal / 100 / (Si Recovery / 100)
FeSi75 (kg) = Si Deficit / 0.75
Mn Deficit = (Target Mn - Scrap Mn) × Total Metal / 100 / (Mn Recovery / 100)
FeMn75 (kg) = Mn Deficit / 0.75
Pig Iron (kg) = C Deficit / 0.04 (Pig ~4% C)
* This calculation gives approximate values. In actual casting conditions, factors such as temperature, slag basicity, and holding time affect recoveries.
