  2. 1. Characterisation of Muko iron ores (Uganda( for defferent routes of iron production

    Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; iron ore; iron; characterization; physical and metallurgical properties; sinter; pellet; blast furnace; direct reduction; Muko; Uganda; Materials science; Teknisk materialvetenskap; SRA - Production; SRA - Produktion;

    Abstract : Iron and its products, especially the various forms of steel, have been and still are a vital material in many sectors of life. It is utilized in many industrial activities ranging from production of heavy duty mechanical equipment to light electrical appliances and home appliances. With the world‟s iron ore consumption estimated to stand at 1. READ MORE

  4. 2. Investigating the parameters that influence the behaviour of natural iron ores during the iron production process

    Author : Abraham Judah Bumalirivu Muwanguzi; Andrey V Karasev; Henrik Saxèn; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; natural iron ore; iron production; characterization; physical and metallurgical properties; sinter; pellet; direct reduction; low temperature degradation; sample weight; sample positioning; microstructure; reduction degree; solid conversion; Volumetric Model; Grain Model; Random Pore Model; Muko; Uganda;

    Abstract : In the iron production processes, sinters and pellets are mostly used as raw materials due to their consistency with respect to physical and chemical properties. However, natural iron ores, as mined, are rarely used directly as a feed material for iron processing. READ MORE

  5. 3. IronArc a New Process for Pig Iron Production : A Numerical and Experimental Investigation Focusing on Mixing

    Author : Kristofer Bölke; Mikael Ersson; Pär Jönsson; Stein Tore Johanssen; KTH; []

    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. Alternative reducing agents in metallurgical processes : Experimental study of thermal characterization of shredder residue material

    Author : Samira Lotfian; Noureddine Menad; Luleå tekniska universitet; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Coal used in metallurgical processes can participate in reduction reactions to produce metals and alloys from oxides. Base metals production leads to generation of slag, which contains valuable metals that can be recovered and recycled. There are several options to treat the slag, depending on the metal content in the slag. READ MORE
