In order to analyze the possible source of large TiN inclusion for the high strength tire cord steel. The remelting experiment was conducted via vacuum induction furnace in the laboratory and the artificially prepared TiN particles which of size 50-74 μm and 100-180 μm were added during the remelting process. Simultaneously, combined with the dissolution kinetic model of TiN particle to make a brief analysis for the genesis of lagre TiN inclusion detected in the wire rod. The results show that the TiN particle which of size 180 μm dissolved in the liquid steel completely at only a few seconds. The TiN inclusions detected in the remelted specimens are all of regular shape, which mainly formed during the solidification process, rather than the added TiN particle which are not completely dissolved. It is supposed that the large TiN inclusion detected in the wire rod most likely spring from the continuous casting mould fluxes.

High-strength tire cord steel is mainly used in radial ply tires, but the presence of brittle Ti inclusions can cause failure of the wires and jeopardize their performance in production. In order to control the titanium content during steel production, a thermodynamic model for predicting the titanium distribution ratio between CaO–SiO2–Al2O3–MgO–FeO–MnO–TiO2 slags during the ladle furnace (LF) refining process at 1853 K has been established based on the ion–molecule coexistence theory (IMCT), combined with industrial measurements, and the effect of basicity on the titanium distribution ratio was discussed. The results showed that the titanium distribution ratio predicted by the developed IMCT exhibited a dependable agreement with the measurements, and the optical basicity is suggested to reflect the correlation between basicity and the titanium distribution ratio. Furthermore, quantitative titanium distribution ratios of TiO2, CaO·TiO2, MgO·TiO2, FeO·TiO2, and MnO·TiO2 were acquired by the IMCT model, respectively. Calculation results revealed that the structural unit CaO plays a pivotal role in the slags in the de-titanium process.
