Abstract��The cause of the formation of cementite in the microstructure of 77B wire rod was analyzed�� and the influence of the network cementite on the drawing property was observed by metallographic observation. In the production process�� making further precise control of carbon content�� strengthening the continuous casting process control to reduce the center carbon segregation in the slab rolling�� strengthening controlled rolling and cooling parameters optimization to eliminate or reduce the network cementite defects suggestion was put forward.
