Magnesia-carbon bricks can be used in the linings of converters and electric arc furnaces, as well as the slag lines of ladles. This dataset includes major raw and auxiliary materials, energy consumption, and atmospheric emissions in the production process; 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 production process of magnesia-carbon bricks includes raw material procurement, batching and mixing, feeding and mixing, forming, framing and pressing, baking, machining, inspection, and packaging.
