Hot rolling - steel (hot rolling - steel)

Emissions generated by the activity within the product supply chain as described in ecoinvent v3.10. This is delivering the service of 'hot rolling steel'. Hot-rolling refers to a mill process in which the steel is rolled at a temperature above its recrystallization temperature with a heat that typically exceeds 1000° F. The hot metal is passed between two rolls to flatten it lengthen it reduce the cross-sectional area and obtain a uniform thickness. Then the steel is cooled at room temperature.The service includes input materials energy and water consumption production infrastructure emissions and waste treatment but it excludes the input of steel to be rolled. Hot-rolled steel typically has a scaly surface finish and it suitable for structural components and other applications where incredibly precise shapes and tolerances are of less importance like railroad tracks I-beams agricultural equipment sheet metal and automotive frames. The cut-off classification is allocatable product. The activity type is ordinary transforming activity. The reference product amount is 1.
