Sulphur removal in ironmaking and oxygen steelmaking

2020-4-9  Calcium carbide For the reaction of sulphur with calcium carbide (reaction (4)) it is assumed that the formed carbon does not dissolve in already carbon-saturated HM16. When CaC 2 is used in steel desulphurisation, where there is no carbon saturation, the dissolution of carbon in iron should be taken into account. CaC 2) =
