  2. 1. A Study on the Reaction between MgO Based Refractories and Slag-Towards the Development of Carbon-free Lining Material

    Author : Huijun Wang; Sichen Du; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; MgO refractory; lining material; carbon-free; clean steel; ladle glaze; slag penetration; dissolution mechanism; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : In present thesis, the fundamental studies on the reaction between MgO based refractories and slag were undertaken for the development of a carbon-free bonding MgO lining material. Alumina was selected as a potential binder material. Due to MgO-Al2O3 chemical reaction, the developed refractory was bonded by MgO·Al2O3 spinel phase. READ MORE

  5. 3. Development Towards Sustainable Ironmaking : The IronArc Process

    Author : Jonas Svantesson; Mikael Ersson; Robert Eriksson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; IronArc; Refractory wear; plasma generator; freeze-lining; Teknisk materialvetenskap; Materials Science and Engineering;

    Abstract : The IronArc process is a novel process for a more sustainable production of liquid pig iron using electricity for heating and hydrocarbons for reduction. This thesis aims to facilitate its use by investigating possible refractory solutions and the gas blowing in the process which is done by a plasma generator. READ MORE

  7. 5. A Study of the Heat Flow in the Blast Furnace Hearth Lining

    Author : Maria Swartling; Pär G. Jönsson; Xuegong Bi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Blast furnace; heat transfer; mathematical model; experimental; Metallurgical process and manufacturing engineering; Metallurgisk process- och produktionsteknik;

    Abstract : The aim of the present thesis was to study the heat flows in the blast furnace hearth lining by experimental measurements and numerical modeling. Thermocouple data from an operating furnace have been used throughout the work, to verify results and to develop methodologies to use the results in further studies. READ MORE
