Abstract:
Tire cord steel is widely used in vehicle radial tire skeleton. The inclusion limits in tire cord steel are strictly and many researchers have paid much attention on the removal of inclusions in steel to improve its cleanliness. In this study, the confocal laser scanning microscopy was used to in situ observe the inclusions behavior of the tire cord steel. The result shows that the capturing of inclusions into the grain interior by the solidification front depends on the cooling rate and the size of inclusions during the process of cooling. The inclusions may be captured into the grain interior if the particles size is larger than the critical diameter at a certain cooling rate. Meanwhile, it is also found that the inclusions which present earlier can be taken as a core of the growth of MnS inclusions. Both the particle size and the amount of the MnS inclusions precipitation decrease with the cooling rate increasing. The particle size of the heterogeneous nucleation inclusions depends on the initial core diameters. Within a certain range, the bigger the diameter of the core is, the smaller the size of the inclusions will be.
