The salient features of the pressure casting are a precisely controlled rate of pouring and a smooth surface of the mold coated with fine alumina powders. Under a suitable operation, the pressure casting process provides a excellent slab surface free from tears and blow holes. Since argon gas purges the mold atmosphere from oxygen, reoxidation of steel is completely prevented during casting. The oxygen content of a pressure cast slab is lower than that of a conventional ingot of the same heat, and most oxide inclusions found in the slab are the primary deoxidation products. Alumina coatings retard effectively the initial rate of solidification, and the amount of inclusions entrapped in the vicinity of the surface is reduced drastically compared with that of a conventional ingot.
