Liquid steel (300 metric tons) initially containing 0.03 mass% sulfur, is desulphurised with calcium (1000kg) according to the reaction, Ca + [S] = Ca S. The slag (1 metric ton) lying on top of metal contains (in mass%) 50% CaO, 25% SiO2 and the rest is Al2O3. Only 10 mass% of the CaO injected reacts with the sulfur and the rest escapes as gas into the atmosphere.
