  2. 1. Modeling of Gas Flows in Steelmaking Decarburization Processes

    Author : Zhili Jack Song; Pär Jönsson; Seppo Louhenkilpi; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; VOD; nozzle; jet; vacuum; BOF; LD; AOD; post combustion; flue; CFD;

    Abstract : The purpose of the current study is to increase the understanding of different steelmaking processes at the decarburization stages by use of mathematical modeling. More specifically, two De-Laval nozzles from a VOD (Vaccum Oxygen Decarburization) process, which is used for producing stainless steels with ultra-low carbon grades, was investigated for different vessel pressures.

  4. 2. A study of some aspects of gas-slag-metal interactions : Towards dynamic process model and control

    Author : Mattias Ek; Sichen Du; Stuart Millman; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; process modeling; phosphorous capacity; penetration depth; slag foaming; mixing time; inclusion removal;

    Abstract : The present thesis deals with the development of a new type of dynamic model for metallurgical reactors. It also covers some of the theoretical aspects of steelmaking that is necessary to include in such an application. The thesis consists of modeling work, high temperature experiments and cold model experiments. READ MORE
