  2. 1. Strategic and operational capabilities in steel production : Product variety and performance

    Author : Joakim Storck; Bengt Lindberg; Christer Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel production; system dynamics; product variety; production strategy; cost models; Manufacturing engineering; Produktionsteknik;

    Abstract : Steel producers that employ niche market strategies are continuously seeking to reduce production cost while maintaining adiverse product mix. The business model is typically based onmarketing of high–strength special or stainless steels. READ MORE

  4. 2. Planning production and supply chain in energy intensive process industries

    Author : Martin Waldemarsson; Helene Lidestam; Martin Rudberg; Magnus Karlsson; Sophie D'Amours; Linköpings universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process industry; Energy-intensive production processes; Energy system; Energy management; Production planning; Supply chain planning; Case studies; Mixed Integer Linear Programming; Modelling; Specialty chemicals; Pulp; Steel;

    Abstract : To make a difference among the energy intensive process industries, this dissertation addresses production planning and supply chain planning problems related to industrial energy management issues. The energy issue is turning more and more important from different angles, involving price as well as environmental problems due to climate change leading to political pressure on all energy users.

  5. 3. The Construction of Construction : The Wenner-Gren Center and the possibility of steel building in postwar Sweden

    Author : Frida Rosenberg; Timothy Anstey; Helena Mattsson; Timothy Hyde; KTH; []
    Keywords : architecture history; architecture technology; Wenner-Gren Center; steel; construction; construction sites; architecture practice; prototype; knowledge production; the Swedish Institute of Steel Construction; postwar Sweden; arkitekturhistoria; arkitekturteknik; Wenner-Gren Center; stål; stålkonstruktion; byggplatser; arkitekturpraktik; prototyp; kunskapsproduktion; Stålbyggnadsinstitutet; svensk efterkrigstid; Architecture; Arkitektur;

    Abstract : The Wenner-Gren Center in Stockholm, built between 1954 and 1966, consists of three buildings dedicated to interdisciplinary and scientific research, designed by Sune Lindström and Alf Bydén of Vattenbyggnadsbyrån (VBB). The project was sponsored by Axel Wenner-Gren, and received support from the Swedish state through the donation of a property at the northern end of Stockholm’s thoroughfare Sveavägen. READ MORE

  6. 4. Steel Beyond Coal : Socio-Technical Change and the Emergent Politics of Steel Decarbonisation

    Author : Valentin Vogl; Miljö- och energisystem; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Steel; coal; climate change; decarbonisation; socio-technical transitions; sustainability;

    Abstract : The steel industry is responsible for 8% of all anthropogenic greenhouse gas emissions and is the second largest user of coal after the power sector. The main emission source in steel production is the blast furnace, which converts iron ore and metallurgical coal into pig iron that is then further refined into steel. READ MORE

  7. 5. A Study on Particle Motion and Deposition Rate : Application in Steel Flows

    Author : Peiyuan Ni; Pär Jönsson; Lage Jonsson; Mikael Ersson; Stein Tore Johansson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; steel flow; ladle teeming; continuous casting; non-metallic inclusion behavior; particle deposition; nozzle clogging; numerical simulation.;

    Abstract : Non-metallic inclusions in molten steel have received worldwide attention due to their serious influence on both the steel product quality and the steel production process. These inclusions may come from the de-oxidation process, the re-oxidation by air and/or slag due to an entrainment during steel transfer, and so on. READ MORE
