Abstract

Abstract

High purity of liquid steel and controlled shape of inclusions were demanded for high strength and low temperature impact ductility of advanced ship plate. The smelting process, purity, and inclusion shape of high-level ship plate of some domestic factories were studied in this paper. The results indicated that the purity of the ship plate steel by the process was high. Inclusions in the casting blanks were mainly globular, whose com-ponent was CaO-CaS-Al₂O₃ and the sizes were less than 10 μm. High-level ship plate with ultra-low oxygen, ul-tra-low sulfur and high purity can be produced by the process of BOF-LF/VD-CC under proper operating condi-tions.
