4. 2. Aspects on slag/metal equilibrium calculations and metal droplet characteristics in ladle slags

   Author : Johan Ekengård; KTH; []
   Keywords : ;

   Abstract : In the present work the mixing between the metal and slagphase during the ladle refining process from tapping from theelectric arc furnace to casting in two different Swedish steelplants has been studied.Three slag models and the sulphur-oxygen equilibrium betweenslag and steel was used together with the dilute solution modelfor the liquid steel phase to predict the equilibrium oxygenactivity in steel bulk and metal droplets in top slag inequilibrium with the top slag.

5. 3. Heat transfer,inclusion characteristics and fluid flow phenomena during up-hill teeming

   Author : Robert Eriksson; KTH; []
   Keywords : Laser flash method; thermal diffusivity; slags; inclusions; water model; ingot casting; up-hill teeming;

   Abstract : Clean steel production requires good control of the sizedistribution and the composition of the inclusions at allstages of the steel making process. So far, there exists verylittle information on the behavior of the inclusion populationduring ingot casting of steel. READ MORE
