Slag forming agents can be used to solve the problem of slag separation in hot metal ladles, reduce the slag crusting rate, improve slag fluidity, and increase hot metal recovery. This dataset includes major raw and auxiliary materials, energy, and waste generated during production; infrastructure such as production equipment and factory construction are not included within the system boundary. The life cycle inventory is compiled from data obtained from multiple sources. The production process of slag forming agents includes procedures such as screening, crushing, fine grinding, mixing, and classification.
