  1. 1. Co-injection of basic fluxes or BF flue dust with PC into a BF charged with 100% pellets effects on slag formation and coal combustion

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lena Sundqvist Ökvist; [2004]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : Based on 100% pellets operation at BF No. 3 at SSAB Tunnplåt in Luleå a new pellet with CaO/SiO2=1 was developed during early nineties. The pellet showed good results in metallurgical laboratory test but caused slag formation problems in the bosh. READ MORE

  2. 2. Optimisation of the slag formation in a blast furnace charged with 100% pellets

    University dissertation from Luleå : Luleå tekniska universitet

    Author : Lena Sundqvist Ökvist; [2001]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

    Abstract : This work is based on experiences from industrial blast furnaces. Process irregularities when testing self-fluxed pellets Process disturbances when charging increased proportions of coarse pellets Laboratory tests to evaluate the effect of basic fluxes on the slag formation in the bosh and in the raceway have been carried out.
