  2. 1. A physical modeling study of top blowing with focus on the penetration region

    Author : Annie Nordquist; Per Jönsson; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Materials science; physical modelling; top blown converters; lances; blowing; penetration; swirl; Materialvetenskap; Materials science; Teknisk materialvetenskap;

    Abstract : This thesis work aimed at increasing the knowledge regarding phenomena occurring when gas is injected using a top-blown lance on to a bath. All results are based on physical modeling studies carried out both using low and high gas flow rates and nozzle diameters ranging from 0.8 mm to 3.0 mm. READ MORE

  4. 2. Mathematical and Physical Simulations of BOF Converters

    Author : Xiaobin Zhou; Mikael Ersson; Pär Jönsson; Hans-Jürgen Odenthal; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; physical model; mathematical model; mixing time; kinetic enregy; Materials Science and Engineering; Teknisk materialvetenskap;

    Abstract : The purpose of this study is to develop mathematical models to explore the mixing and its related phenomena in converter bath. Specifically, first, a mathematical model of a physical model converter, which was scaled down to 1/6th of a 30 t vessel, was developed in this study. READ MORE
