Dataset description

Continuous casting of ladle-treated alloy steel into semi-finished billets/blooms suitable as feedstock for bar/rod rolling. Included explicitly per the route option sequence.

Technology description

Production of further-worked alloy steel bars/rods starting from primary steelmaking in an integrated steel plant (blast furnace–basic oxygen furnace), followed by casting to semi-finished product (billet/bloom), hot rolling to bar/rod, then additional downstream operations beyond hot/cold processing to obtain the finished manufactured product at plant.; Continuous casting of ladle-treated alloy steel into semi-finished billets/blooms suitable as feedstock for bar/rod rolling. Included explicitly per the route option sequence.; The flow is a finished manufactured product and the mix is a production mix at plant; route is modeled as a plant-level product system up to the finished bar/rod output.; ‘Further worked than hot- or cold-processed’ implies at least one additional post-rolling/post-drawing finishing step (not specified in the flow), represented generically as downstream finishing operations.; Energy and GHG accounting for steelworks operations can follow steel-plant internal accounting boundaries described in the primary cluster reference, but product-specific finishing detail is not provided in the given sources.

Geographic context

Casting is modeled as occurring at the same China plant as upstream steelmaking, consistent with an integrated steelworks route.
