Ferrosilicon heating agent is added during the early stages of converter and electric furnace smelting to better provide heat, increase molten steel temperature, and accelerate slag formation. This dataset includes main 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 of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The manufacturing process of ferrosilicon heating agent includes material receiving, weighing, mixing, conveying, pelletizing, drying, and packaging.
