In order to improve the technical level of the Tangsteel medium and heavy plate company and improve the competitiveness of the product market, a number of the new generation of production technologies have been introduced. The high quality billet manufacturing technology such as the control technology of the billet corner cracks in microalloy steel and heavy reduction at the solidification end of the casting realized the high quality slab production. An advanced plate mill control system integration and MAS rolling board type control technology and other highyield mediumthickness plate rolling technology were introduced, which improve the sheet material highyield rate. The implementation of the new generation ultrafast cooling (UFC) TMCP equipment and alloy subtraction technology in Tangsteel was introduced. The application of these technologies has realized the upgrading of the medium and heavy plate in Tangsteel and promotion of the quality of the heavy plate.
