| Abstract: | Proceeding from a review on the production process of the wire rod and the reinforcing bar of the pipe pile the causes to the cracking of the reinforcing bar tip of 30MnSi pipe pile are carefully analyzed.Results indicate that the linear defects such as the surface scratching and folding may probably lead to the damage of the bar tip besides two traditional influencing factors,heat treatment of the reinforcing bar and the quality of the wire rod steel. |
