  • Casting steel ingots
    Patent number: 3998261
    Abstract: In the bottom pouring of steel ingots, the molten steel is teemed into a trumpet or upstanding runner and passes from the trumpet through a horizontal runner and up into an ingot mould. Inert gas is injected into the molten steel as it passes downwardly through the trumpet so that bubbles are formed in the steel, which bubbles assist in the removal of non-metallic inclusions. This process is used in the manufacture of steel ingots of very low non-metallic inclusion content and low total oxygen content.
