RESEARCH AND APPLICATION OF TMCP TO IMPROVE THE STRENGTH AND TOUGHNESS OF HIGH STRENGTH AND SUPER THICK H-SHAPED STEEL
The TMCP is used to produce thick high-strength H-beam steel.Granular or strip bainite is produced on the flange surface,so that phase transformation strengthening plays a very important role in H-beam steel.The grain at the core is smaller,and the grade of ribbon structure is effectively reduced,which effectively improves the strength and toughness of H-beam steel.
