| Abstract: | The purity of steel has direct effect on its mechanical properties, the oxygen content.inclusion quantity, the component of inclusion and the inclusion appearance were analyzed , and also the surface flaw was counted. The result shows that the main type of inclusions in the ER70s-6 weld wire steel is complex oxide system, including MnO-Al2O3-SiO2-CaO system, MnO -SiO2 system and there are two surface flaw on the continuous cast slab, one is surface pores, the other is surface crack. |
