Industrial application of control technology of oxide inclusions in tyre cord steel

In steel making for tyre cord, weak deoxidation, prevention of reoxidation, and control of ba-sicity and Al₂O₃ content in refining slag were adopted to decrease the melting point of inclusions in liquid steel and promote floating upward of inclusions. It was proved that the composition, size and deformation ability of inclusions in tyre cord were promoted by the application of the abovementioned technologies.
