| Technology description including background system | The data set represents the steel production in Germany based on the main production steps which take place within an electric steelmaking plant. The main process step hereby is the melting of scrap in the electric arc furnace (EAF), thus the consumed energy is mainly electric power. The major feed stock for the EAF is ferrous scrap, which may comprise of scrap from inside the steelworks (e.g. cut-offs), cut-offs from steel product manufacturers (e.g. vehicle builders) and post-consumer scrap (e.g. end of life products). As in the integrated steel plant including blast furnaces and converters, a slag is formed from lime to collect undesirable components in the steel. Thus lime is an additive as well as coal (carbon) as reducing agent. Oxygen lances and / or oxy-fuel burners are used to assist in the early stages of melting. For every material fraction the transport is considered in the data set. For the production of carbon steel and low alloyed steels, following main operations are performed: raw material handling and storage, furnace charging with/without scrap preheating, EAF scrap melting, steel and slag tapping, ladle furnace treatments for quality adjustment, slag handling and finally continuous casting. The output of the continuous casting is the steel slab. Afterwards the slab is manufactured in a wire drawing process. The main property of reinforced steel is its bond with the surrounded concrete. To improve the bond the wire is ribbed. In the disposal phase, mechanical dismantling is accounted for in module C1 for steel products (excavator), for all other metals a manual dismantling is assumed (no loads). Collecting losses are neglected. It is assumed that all metals reach the end of the waste status immediately after dismantling. This means that the loads for processing and the credits for the substitution of primary material are shown in Module D. The transport in module C2 to the treatment plant takes place with a truck (50km). Module D includes loads for sorting, remelting, slag treatment, landfill, filtration of dusts and dross treatment. Credits are given for the net scrap amount (amount returned minus secondary material content, minus processing losses) for the average material mix (from different alloys). | ||
