Method for producing chromium containing molten iron with low sulphur concentration

摘要

Reduction of chromium oxide is performed by utilizing refinement or reduction container having top-blowing capability. Chromium oxide is charged in the molten iron bath in the aforementioned container. Content of slag is adjusted to maintain the following condition:P P CaO/SiO.sub.2 :2.1 to 3.5PPMgO/Al.sub.2 O.sub.3 :0.6 to 0. 8
