Abstract

Abstract

The morphology and sizes of inclusions after liquid steel Ca treatment,in the slab and in the plate were researched by SEM for high strength and low alloy (HSLA) steel containing 0.065%Ti.The composition of inclusions was studied by EDS.The results show that most of inclusions in the slab and plate are CaO-Al₂O₃-TiO_x-CaS inclusions,and few of them are TiN inclusions. The inclusions have been modified well by Ca treatment.The precipitations of TiN and CaS have been analyzed by thermodynamic calculation.
