Method for producing molten iron containing low S chromium

摘要

Reduction of chromium oxide is performed by refining or reducing top-blown vessels. Chromium oxide is charged in the molten iron bath in the aforementioned vessel. Content of slag is adjusted to maintain the following equation: CaO/SiO2 : 2.1 to 3.5 MgO/Al2O3 : 0.6 to 0.8
