Chromium ore should be a dry, clean lump or concentrate with a lump size of less than 50mm; Containing Cr2O3>40%, Cr2O3/ Σ FeO>2.0, phosphorus content should not exceed 0.03%. Select silicon chromium alloys with different carbon contents based on the grade of the micro carbon engraved iron smelted. When smelting low-carbon iron with a carbon content of 0.06%, the carbon content of silicon chromium alloy should be less than 0.06%; When smelting
