Abstract

Abstract: The formation mechanism of "white band" and central carbon segregation of high-carbon Cr bearing steel concasting billets are discussed in this paper. The maximum oxygen content in the steel produced by concasting process was 13 x 10(-6) with an average oxygen content of 9.3 x 10(-6) Comparison of metallurgical quality and fatigue property between the concasting steel (CC) and ingot casting steel (IC) showed that the carbon segregation (C/C-0) in former steel was 0.92 similar to 1.10 and its fatigue life was equal to that of the latter steel.
