| Abstract: | By adopting the process of TMCP, low alloy and high strength steel Q345E was produced, which could meet the comprehensive mechanical properties of high yield strength and high tensile strength and high tension required by the customer. In this process, the purity of molten steel was strictly controlled, the rolling temperature for the last pass was reduced, and forced cooling by cold bed blower fan was performed, which could efficiently raise the strength and low temperature toughness of the steel product. |
