The technological process and the properties of 20CrMnTi, 40MnB, 60Si2Mn, and 55SiMnVB steels smelted in Pangang 120 ton converter are described. The problem of control of chemical compositions of steels is solved through the technical measures of ladle refining, i.e. calciumbase Pre-doxidizer addition, aluminium wire feeding and complex cored wire feeding into molten steel in ladle before steel tapping and the technical improvement of Fe-Cr alloying process.As aresult, the required harden ability and cleanness of steels are ensured.The 20CrMnTi, 40MnB, 60Si2Mn, steels are perfectly suitable to use in automobile industry.
