“…This is because during the wire drawing process of cord steel, the wire rod normally suffers an extremely high level of deformation in its length direction. Therefore, the filament break or delamination phenomenon is likely to happen, [1][2][3] which may directly affect the wire integrity or deteriorate the fatigue properties of the steel cord products and finally decrease the cord steel productivity and quality. Based on the former investigations, the above undesirable phenomena are mainly caused by the existence of the high hardness inclusions precipitated in the tire cord steel.…”

TiN, a typical non‐metallic titanium inclusion, is regarded harmful for the quality of hypereutectoid tire cord steel. At present, the effective methods of controlling the TiN inclusions in the high carbon tire cord steel are still uncertain. In this work, the precipitation and solid solution behaviour of the TiN inclusions in SWRH92A tire cord steel are studied. The main characteristics, e.g. size distribution and morphology, of the TiN inclusions precipitated under different steel re‐melting conditions (e.g. Ti and N concentrations and cooling rate) are analyzed. The results indicate that the average TiN inclusion size is proportional to the Ti and N concentration product, and Ti shows larger effect on the TiN inclusion size than N. For the samples with heat treatment, the number percentage and average size of larger TiN inclusions decrease compared with reference sample. As heating temperature increases from 1150°C to 1250°C, the total TiN inclusion number decreases, and the number percentage and average size of larger TiN inclusions decrease. After heating, the sample with a higher cooling rate has a higher number percentage of finer inclusions and the average size of larger inclusions is smaller, indicating that increasing cooling rate is helpful to refining the TiN inclusions.This article is protected by copyright.
