  1. 1. Top Gas Blowing Technique to Prevent Slopping in Ladle and Basic Oxygen Steelmaking Process

    University essay from KTH/Materialvetenskap

    Author : Abdullah Harazeen; [2022]
    Keywords : slag; slag foaming; slopping prevention; BOS; LD converter; ladle furnace; foaming index; and cold model experiment;

    Abstract : In the steel industry, slag foaming plays a crucial role in many steel processes, given its positive impact on the thermal efficiency of the furnace and its life span. However, excessive foaming causes an overflow in the converter known as “slopping”. READ MORE

  3. 2. Utilization of Pulp and Paper Waste Products in the Metal Industry : Initial testing of carbon-containing waste material briquettes

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Ingrid Johansson; Walter Deltin; [2018]
    Keywords : pulp and paper waste products; recycling; biosludge; fiber reject; drop test; slag foaming with briquettes; circular materials;

    Abstract : Today, a huge part of waste products from pulp and paper industries ends up in landfill which is both economically and environmentally adversely. This report examines the possibilities of using those products as a slag foamer and fuel in different furnaces in the metal industry. The waste products contain valuable elements, especially carbon.

  4. 3. The effect of carbonaceous iron on slag foaming

    University essay from KTH/Materialvetenskap

    Author : Josefin Svensson; [2018]
    Keywords : ;

    Abstract : The practise of slag foaming has become increasingly important within the scrap-based steelmaking, conducted in the electric arc furnace, due to its many advantages. In addition to increasing the efficiency in the furnace, the foaming protects the furnace equipment from wear and reduces noise pollution. READ MORE

  5. 4. The Viability of Oxygen Gasblowing as a Foaming Slagsuppression System for Slopping Prevention in BOF-Processes

    University essay from KTH/Materialvetenskap

    Author : Teodor Haglund; Joar Huss; [2016]
    Keywords : BOF; Foaming slag; Slopping prevention; Gas jet;

    Abstract : Slopping in BOS-processes poses many problems, most significantly to work environmentand process effectiveness. Due to the current weaknesses in slopping prediction systems afoaming slag suppression system with immediate effect is needed to prevent slopping. READ MORE

  6. 5. Effect of the presence of a dispersed phase (solid particles, gas bubbles) on the viscosity of slag

    University essay from KTH/Mikro-modellering

    Author : Galina Albertsson; [2009]
    Keywords : Mathematical modelling; Physical modelling; Slag viscosity; Slag foaming.; Математическое моделирование; физическое моделирование; вязкость шлака; вспенивания шлака; 数学建模，物理建模，炉渣粘度，泡沫渣; Matematisk modellering; fysisk modellering; slaggviskositet; slaggskumning;

    Abstract : The viscosities of a set of silicone oils containing different size ranges of charcoal or paraffin particles as well as the viscosities of silicone oil foams were measured at room temperature in order to determine the effect of dispersed phase on the viscosity of a liquid and its effect on foaming ability. The effective viscosity of the samples increased with volume fraction of the second phase. READ MORE
