<p>The process for preparing a ferrochromium by using a blast furnace is improved by charging briquettes or pellets containing chromium ores and a carbonaceous reducing agent into the blast furnace, as well as by determining the operational conditions of the blast furnace, such as the theoretical combustion temperature at the tuyere ends and the pressure at the top of the blast furnace. According to the improvement, the degree of reduction chromium ore is high, and the blast furnace operation can smoothly performed without accidents, such as scaffolding and flooding.</p> |
