ABSTRACT:
The precipitation of TiN inclusion
during solidification of different carbon content of 0.72%, 0.82% and 0.95% in tire cord steel is thermodynamically studied
respectively. The results show that the carbon content has obvious effect on
TiN inclusion precipitated in tire cord steel of different strength levels. With
the carbon content of tire cord steel increasing, the temperature before solidifying reduced gradually and the
required activity product of titanium and nitrogen for TiN inclusion
precipitation also declined gradually. With the same condition of initial Ti and
N content in liquid steel, the size of TiN inclusion precipitated in tire cord
steel of higher carbon content is bigger than that of lower carbon content. In
order to control the harmful effects on processability of TiN inclusion
precipitated in hypereutectoid tire cord steel of the ultra high strength level, the
measures of smelting process must be taken to further reduce the titanium and nitrogen
content in liquid steel.
