The effect of original finish rolling process [finish rolling at ≥930℃. and wire coiling at (870 土 10) ℃] and improved finish rolling process [finish rolling at ≥950 ℃and wire coiling at (900 ± 10) ℃] for φ5.5 mm 0.73% C 72A tire cord steel coil on its structure

texture and mechanical properties has been studied by using scanning electron microscope (SEM)

X-ray diffractometer (XRD) and tensile testing machine. Results show that with increasing finish rolling and wire coiling temperature respectively by 20 °C and 30 ℃

the distance between pearlite lamellae in steel decreases from 144 nm to 133 nm

the tensile strength and plasticity of steel increase slightly

while the intensity of {111} texture along the axis of wire rod decreases and the peeling rate of oxide scale increases from 1. 66 kg/t to 2. 67 kg/t

that are favorable to increase the drawability of tire cord steel.
