Novel concept of cleansing liquid steel of solid oxide inclusions by cullet injection in ladle

Abstract

Disclosure is made of a novel process of steel refining in the ladle with cored wire injection of soda lime cullets to cleanse the steel of solid oxide, aluminosilicate and sulphide inclusions. This refining process is expected to improve steel castability, minimise surface defects in the casting, improve many metallurgical properties of steels for various applications and improve the machinability rating of resulphurised, free machining steel for continuous casting.
