2. 1. Influence of Ladle-slag Additions on BOF-Process Parameters

   Author : Anders Dahlin; Pär G. Jönsson; Joel Gustavsson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; BOF; slag formation; ladle slag; recycling; steel; composition; energy; Metallurgical process engineering; Metallurgisk processteknik;

   Abstract : The influence of ladle-slag additions on the BOF-process performance were investigated in plant trials. The aim of the study was to recycle ladle slag from secondary steelmaking to the LD-converter to save lime and improve the slag formation. READ MORE

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

5. 3. Study of Sulfide Capacity of Slag and Sulfur Removal from Hot Metal

   Author : Adolfo Firmino Timoteo Condo; Du Sichen; Robert Eriksson; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Metallurgical process science; Metallurgisk processvetenskap;

   Abstract : The present study aims at investigating the desulfurization process in hot metal and sulfide capacity of slags. The missing experimental data of sulfide capacities in Al2O3-CaOMgO-SiO2 system at 1713 K, 1743 K, 1773 K, 1823 K, 1873 K and in the Al2O3-CaO-SiO2 system at 1873 K were investigated under wellcontrolled oxygen potentials.

6. 4. Mineralogical influence of different cooling conditions on leaching behaviour of steelmaking slags

   Author : Fredrik Engström; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Process Metallurgy; Processmetallurgi;

   Abstract : The Swedish steelmaking industry produces large amounts of by-products. In 2006, the total amount of slag produced reached approximately 1 375 000 metric tons, of which 30% was deposited. Due to its strength, durability and chemistry, steel slag is of interest in the field of construction due to it's similarities with ordinary ballast stone. READ MORE
