General comment on data set ecoQuery: https://ecoquery.ecoinvent.org/3.10/cutoff/dataset/23131/documentation This dataset describes the hot rolling of steel in Austria. The data are based on an Austrian company which produces reinforcing steel including the hot rolling process. Since the steel billets are produced on site, they are generally still hot when entering the hot rolling process, only a small share of the billets have to be reheated. This increases the energy efficiency of the hot rolling. The steel production is not included in this dataset.;There are two co-products that are used in other industries: Scale (material formed through oxidation of the cooling billet) can be used in steel production, cement production, and refractory production. Heat is used in the communal district heating grid. This process starts with the arrival of steel billets. Hot rolling steel into rebars or coils. Bending is not included in this dataset.

Time representativeness
Data set valid until 2023
Time representativeness description The process is expected to be valid for the next 10 years. The energy efficiency and emissions may improve in the next years.
Technological representativeness
Technology description including background system The hot rolling process descibes the production of rebars and coils for reinforcing steel from steel billets. Rebars have a diameter of 8-40mm and a length of 6-30m. Coils have a diameter of 8-16mm and weigh 1.7, 3.0 or 5.0. The average steel grade is B550 or B500 (550 or 500 MPa).

Data sources, treatment and representativeness
Data treatment and extrapolations principles In case the company did not provide accurate data, data from the dataset "hot rolling, steel [RER]" were used.
Data source(s) used for this data set
Sampling procedure The data was provided directly by the steel production company. For the year 2017, the input material flows were given in absolute numbers and per ton of produced steel.

General comment Measured Value. During the cooling of the steel, there is a material loss through oxidation at the surface. This material loss is called scale. Scale is first stored and then sold. It can be used in steel production, cement production, and refractory production.
