Abstract: Industrial experiments of Q345E continuous casting were carried out with rolling millin Baotou Iron and Steel(Group)Co.. Based on chemical composition of the Boron-added HSLA H-beam, the composition of the new H-beam was designed, and Vanadium was added in the new H-beams together with trace boron so as to further reduce its DBTT. The values of low-temperature impact energy are much better. Inclusions and grain size control-ling level are improved.
