Practice of Steelmaking Process Control for Industrial Pure Iron Under High Phosphorus Molten Iron Conditions
The process flow of producing industrial pure iron under high phosphorus molten iron conditions was studied.The KR(desulfurization)-LF(further desulfurization)-converter(decarburization and dephosphorization)-LF(dephosphorization and heating)-RH(decarburization and aluminum insulation)-continuous casting process was used to successfully develop high-purity industrial pure iron.The smelting process reached the first-class level of domestic raw material grade industrial pure iron,and LF desulfurization further stabilized the S content in the converter.The converter reduced the P and Mn content through dual slag,carbon control,and temperature control.The vacuum circulation system of RH controlled a series of operations such as C,Al,and O to complete the smelting of industrial pure iron.
