Abstract

In order to manufacture pseudo-rimmed steel by continuous casting, which has been strongly required, a stable production system is established by improving continuous casting process together with BOF and RH processes as one totalized process.
In the BOF, oxygen blowing is ended at the constant carbon content of 0.10% for the reduction of FeO content in slag. Precise composition adjustment is made in the following RH process. Furthermore, the constant high speed casting under non-oxidizing condition is employed to ensure the good surface quality of cast slabs.
