Study on Microstructure Defects of High-Carbon Wire Rod SWRH82B Drawing Fracture
In this paper,SWRH82B steel as the object of study,analysis of several typical drawing fracture tpyes to explore the reasons for fracture by SEM testing.The results show that:the type of slope-type fracture mainly due to cracks defects generated in surface of the wire rod;the Pen-shaped type fracture due to central segregation in the continuous casting process;whole flat brittle fracture mainly due to a serious slag in the continuous casting process.
