CCS-E Ship Plate Fixed Rolling # Wugang Xiangyang

CCS-E Ship Plate Executive Standard: GB/T712-2011.

GB/T712-2011 Structural steel standard for ships and offshore engineering The grades specified are: A, B, D, E, AH32, DH32, EH32, FH32, AH36, DH36, EH36, FH36, AH40, DH40, EH40, FH40, AH420, DH420, EH420, FH420, AH460, DH460, EH460, FH460，AH500，DH500，EH500，FH500，AH550，DH550，EH550，FH550，AH620，DH620，EH620，FH620，AH690，DH690，EH690，FH690。

CCS-E Boat Plate: The on-board specifications that can be produced are 5-80mm x 1500 -3900mm x 3000-12000mm. Judging from the production of CCS-E ship plate varieties in recent years, the output of general-strength A and B ship ships accounts for 90%, and the output of high-strength ship plate is less than 10%. General strength D, E class ship board and high strength ship board.

D, E series ship plates are required to have good low-temperature toughness, good welding performance, which must be guaranteed in the steel smelting process first, and secondly, effective control rolling and cooling processes must be implemented.

In recent years, major domestic iron and steel companies have fully realized the importance of improving the internal quality of steel, relying on the progress of smelting technology to improve molten iron desulfurization slag, steelmaking hydrogen blowing, vacuum refining outside the furnace, etc., to significantly reduce the harm of steel. The content of elements and impurities.

The navigation environment of CCS-E ships is harsh, the hull shell bears large wind and wave impact and alternating loads, coupled with the complex processing and forming technology of the ship, etc., the steel requirements for the hull structure are very strict. As China moves from a shipbuilding country to a shipbuilding power, ships are developing in the direction of large-scale and lightweight, and the steel materials used are required to be high toughness, high strength, high cleanliness, easy welding and low cost. The use of E-grade shipboard steel has increased year by year, and the strength has also transitioned from general strength to higher strength
