Abstract
PURPOSE: To obtain the underwater castings of good internal quality by adding the deoxidizer of 2W10 times the amount of the deoxcidizer necessary for equilibrium deoxidation in atmosphere casting to molten steel before pouring the molten steel into water.
CONSTITUTION: In the underwater casting method involving pouring of molten steel into water, the deoxidizer of 2W10 times the amount of the deoxidizer necessary for equilibrium deoxidation in atmospheric casting is added to the molten steel before pouring. As a result, internal cavities may be prevented. Namely, in the case of underwater casting, the absorption of the gas formed through decomposition of water during underwater freezing is large and the amount of the deoxidizer necessary for the equilibrium relation in atmospheric casting becomes insufficient and particularly the amount of oxygen absorption reaches more than ten times that of the atmospheric castings. Because of this the amount of addition of the deoxidizer becomes important. In this way, the underwater castings of good internal quality free from internal cavities are obtained.
