Study on Inclusions of Casting Billet and End Product of T700 High Strength Construction Steel
The size distribution and component inclusion in casting billet and end product of T700 were investigated by optical microscope and SEM.The results show that the mount and size of inclusion both slight decrease.By energy spectrum analysis,the composition is sulfide,silicate,magnesium salt,titanate and calcium.The size of inclusions in end product is below 5μm and the mount is small.
