An investigation was made of distribusions and chemical compositions of large inclusions in rising capped steel, Al semi-killed steel, and Al-Si killed steel ingots, and the origin and behavior of the large inclusions during solidification of ingots were clarified.
The large inclusions are formed as a result of the coagulation of the deoxidation product in the mold to the exogenous inclusion such as the steelmaking slag and the errosion product of refractories, and the deoxidation product in the ladle.
The ratio of the mold deoxidation product in the large inclusions increases as the size of the large inclusions decreases.
