Elimination of nitrogen from steel by synthetic slags

The increase of the nitrogen transport in the slag is improved when the surface activity of the oxygen and sulphur in liquid steel is decreased and in interface resistant against the metal reduction. Presented are the conditions for the nitrogen transport from steel to slag. The degree of the nitrogen desorbtion from the liquid steel has changed depending on the chemical composition of the slag, on its basicity, on the slag amount, oxygen and sulphur content in metal, or in slag respectively. The oxygen potential on the system was controlled by the research work the denitrogenization and insulation ability of the casting powder MOLD Z-5 used in VSŽ a.s. were tested.
