The wire for steel cord of tyre is a high carbon steel(0.70~0.75C-0.15~0.30Si-0.40~0.60Mn)
which is widely applied to auto tyre and conveyer belt industries because the rubber products stengthened with 40.15~ 0.38 mm steel cord has excellent strength and springiness which is available to increase the safety of car and decrease fuel expenses. Due to requirement of high quality on wire for steel cord of tyre
in general the process flow sheet :converter or arc furnace- LF- VD or RH-Ca treatment- concasting is adopted to produce the steel.The control of chemical compositions
gas content and inclusion is presented and the general conditions of production
quality requirement and development trend of wire for steel cord of tyre at home and abroad are summarized in this paper.
