Abstract
PURPOSE: To manufacture low-Ti and high-C ferrochromium inexpensively and easily by restricting the ratio of MgO/Al2O3 in blended starting material, the ratio of fixed carbon (F.C)/Cr2O3 in chromium ore and the amount of SiO2 in produced slag to specified values.
CONSTITUTION: Blended starting material is prepared so as to adjust the ratio of MgO%/Al2O3% in the material to ≥1.5. A carbon material is added so as to adjust the wt. ratio of the amount of fixed carbon to the amount of Cr2O3 in chromium ore to 0.30W0.40, and silica is added so as to adjust the amount of SiO2 in produced slag to 30W45%. By refining the prepared starting material in an electric furnace to remove Ti, low-Ti and high-C ferrochromium can be manufactured using chromium ore relatively rich in Ti without carrying out forced removal of Ti by refining at the outside of the furnace.
