  • Treatment Of Steel In Its Molten State (AREA)

Abstract

PURPOSE: To produce steel for steel cords of 20 or less in nonductile inclusion index by predeoxidizing the molten steel which has been tapped under perfect Al control by using the flux containing CaO then blowing a slight amount of the alloy containing one or more kinds of Ca, Mg and REM.
CONSTITUTION: The flux containing CaO is blown together with inert gas into the foregoing molten steel in a ladle, by which the molten steel is predeoxidized until the total oxygen at the tapping reaches the hitting levels of approximately 20W 30ppm. Next, the alloy containing one or more kinds of Ca, mg and REM (rare earth elements) is added in a slight amount (e.g. 0.1W0.2kg/T-S) in this molten steel after the predeoxidation to soften its inclusions. The inclusions formed at this time become the inclusions of low melting points of multiple-element base of MnO, SiO2, Al2O3, CaO and MgO. As a result of this, the steel which is used for wire materials for steel cords of 20 or less in nonductile inclusion index is obtained.
