Analysis on Low Mechanical Properties of Hot Rolled Ribbed Bars(HRB400) |
|
|
|
Abstract Aimed for the low mechanical properties of hot rolled ribbed bars, such methods as chemical composition, macrostructure,SEM of fracture, slag inclusions analysis were used for product analysis.The results showed that large size in microstructure, serious ferrite network, large inclusions in Base metals, the strengthening effect of vanadium did not give full play etc. were the main reasons which leaded to the low mechanical properties of hot rolled ribbed bars.According to the analysis results��technological improvements were taken,and the phenomenon of the low mechanical properties of ribbed bars was eliminated.
