Deoxidizers can be used for deoxidizing molten steel, reducing the melting point of deoxidation products, promoting the flotation of deoxidation products, and modifying the morphology of inclusions. This dataset includes the main raw materials, auxiliary materials, and energy used in the production process; infrastructure such as production equipment and plant construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data sourced from multiple references. The production process of deoxidizers includes raw material mixing, crushing, weighing, and grinding operations.
