摘要

A low cost steel desulphurating agent includes, compared with the total weight of the agent, at least 10% of SiO₂, at least 10% of C2S, and at least 35% of at least one of calcium aluminate or calcium silico-aluminate. The desulphurating agent can include, compared with the total weight of the agent, the following mineralogical phases: 10 to 60% of C2S, 0 to 50% of C3A, 0 to 50% of C2AS, 0to 70% of C12A7, and 0 to 60% of CA.
