Smelting chrome ore 855 Low carbon levels are more readily attained with a lumpy, coarse ore and when the slag has a MgO/Al^ ratio of approximately unity. Higher values of MgO/Al^ are especially deleterious. The presence of CaO also raises the carbon level. The influence of these factors can be explained by their effect on the temperature of ...

Ferrochrome –silicon is another chromium ferroalloy directly produced from chromite ores by carbothermic reduction in submerged arc furnace. The chromium content ranges from 34 to 42%, that of silicon from 38 to 45%, and that of carbon from 0.05 to 0.06%. The mix order is similar to that of smelting high-carbon ferrochromium except that it ...
