Aluminum deoxidizer can be used for deoxidizing molten steel and reducing the melting point of deoxidation products. The dataset includes major raw, auxiliary materials and energy consumed during production, but infrastructure such as production equipment and factory construction is not included within the system boundary of the dataset. The life cycle inventory is compiled from data obtained from multiple sources. The production process of aluminum deoxidizer includes batching and homogenization, semifinished product inspection, pelletizing, collection, drying, inspection, and packaging.
