Tundish metallurgy : a combined Irsid and Hoogovens research^*

Métallurgie en répartiteur : recherche commune Irsid-Hoogovens

Abstract

The tundish is an effective metallurgical reactor for the improvement of steel cleanliness. During the last two years, in a joint research program, Hoogovens and Irsid have examined several aspects of tundish metallurgy. Different advanced techniques have been studied :

• –

  basic powders, as a metallurgical active slag ;

• –

  dams and weirs, for flow control; an optimization of fluid flow has been assessed with the use of modern numerical calculation techniques ;

• –

  filtering, argon bubbling and control of the atmosphere in the tundish are aids to decrease the oxidic level in the steel.
