Abstract: Analysis results show that the center segregation of continuous casting billet is serious, easy to cause cup and cone fracture when the rod is drawn； the non-metallic inclusions in the wire rod cause the wire fracture due to the stress when the wire rod is pulled out and twisted; if the content of O and N in steel is too high, the strength and hardness of steel will increase, and the toughness will decrease； reasonable coiling temperature and cooling rate can ensure the ideal micro structure o£ the wire rod. By controlling [O]≤20 X 10^-6, N]≤40 X 10^-6,costing liquid superheating ≤25℃,, rolling billet heating at 1100~1170 ℃ and coiling at 910~93O℃ etc process measures the drawing fracture is avoided.
