    Author : Leo Carlsson; Pär Jönsson; Peter Samuelsson; Mikael Vejdemo-Johansson; Henrik Saxen; KTH; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Electric Arc Furnace; Electrical Energy Consumption; Statistical Modelling; Machine Learning; Interpretable Machine Learning; Predictive Modelling; Industry 4.0; Ljusbågsugn; Elenergiförbrukning; Statistisk Modellering; Maskininlärning; Tolkningsbar Maskininlärning; Prediktiv Modellering; Industri 4.0; Teknisk materialvetenskap; Materials Science and Engineering; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The steel industry is in constant need of improving its production processes. This is partly due to increasing competition and partly due to environmental concerns. One commonly used method for improving these processes is through the act of modeling. READ MORE

  4. 2. Application of Process Integration for Electric Arc Steelmaking

    Author : Philip Lingebrant; Jan-Olov Wikström; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy Engineering; Energiteknik;

    Abstract : In today`s steel industry about one third of the total steel production is produced by electric arc steel making. The production of steel is a very energy intensive industry, but when considering the total cost of the final steel mill product, it is the cost of raw materials that are dominating. READ MORE

  5. 3. Minimisation of Chromium Leaching from Low-Alloy Electric Arc Furnace Slag by Mineral Modifications

    Author : Ida Strandkvist; Fredrik Engström; Rainer Backman; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; slag; leaching; minerals; Process Metallurgy; Processmetallurgi;

    Abstract : Iron and steel are produced continuously as a vital part of modern life. The largest by-product of metal production is slag. Slag is an essential part of the production of steel since, in the furnace, the molten slag removes impurities from the metal. When the slag which consists of oxides, solidifies minerals form.

  6. 4. Management of technology in the process industries:  Matching market and machine

    Author : Peter Samuelsson; Pär Jönsson; Rob Boom; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; process industries; manufacturing; innovation; configuration; strategizing; capability; configuration modelling; process industries; production system; physical modelling; AOD; converter geometry; injection; mixing times; electric arc furnace; EAF; post-combustion; high-impedance; network disturbances; operational results; Metallurgical process science; Metallurgisk processvetenskap;

    Abstract : The process industries span multiple industrial sectors and constitute a substantial part of the entire manufacturing industry. Since companies belonging to this family of industries are often very asset intensive, their ability to respond to changes is often limited in the short term. READ MORE

  7. 5. Energy and scrap optimisation of electric arc furnaces by statistical analysis of process data

    Author : Erik Sandberg; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Modern process logging systems for electric arc furnaces have the capability of storing large quantities of data, both in terms of variables and number of heats. The objective of this research is to evaluate how this data can be used for improvement of operating practices and optimisation of energy and scrap utilisation. READ MORE
