| Abstract: | The low-alloy and high-strength steel Q345D has been produced by the controlled rolling and controlled cooling process,which achieves the integrated mechanical property of high yield strength and high tension strength required by the customer.The process of strictly controlled molten steel purity,reducing finishing rolling temperature and forced cooling on cold bed blower fan could efficiently raise the strength and low temperature toughness of the steel product. |
