| Abstract: | The causes and formation mechanism of surface cracks on the N80 grade oil well pipe made by Hengyang Steel Tube Co.,Ltd.are analyzed in this paper.It is found that the surface cracks are generated in the puncturing process due to a mass of inclusions in the cast.It's possible to reduce the cracks effectively by controlling steelmaking process properly,improving the quality of continuous casting billets,and optimizing the puncturing process parameters. |
