Ultrasonic testing principle of RINA grade A floating dock steel

Shipbuilding steel plates are used to manufacture marine and inland watercraft hulls, requiring high strength, plasticity, toughness, cold bending performance, welding performance, and corrosion resistance. The company provides common shipboard grades such as Grade A, Grade B, Grade D, Grade E, Grade AH32, AH36, AH40, DH32, DH36, DH40, EH32, EH36, EH40, FH32, RINA grade A floating dock steel FH36, FH40.

Land transportation inquiry: (RMB fee) it is required to master the kilometers and towing price of major cities; packing price of each port area; customs clearance fee, commodity inspection fee, and animal and plant inspection fee standard. Key information to be clarified after accepting the consignation of the consignor (generally fax): shipping date, number of packages, box type, box quantity, gross weight and volume.

Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter RINA grade A floating dock steel steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.

Steel RINA grade A floating dock steel exports fell sharply year on year. According to the data of the General Administration of customs, 7.811 million tons of steel were exported from January to February, a year-on-year decrease of 27.0%; 2.041 million tons of imported steel, a year-on-year increase of 2.1%. Steel prices continue to fall. According to the monitoring of China Iron and Steel Industry Association, China's steel RINA grade A floating dock steel composite price index at the end of January was 105.48 points, down 0.58% month on month; at the end of February, the index continued to decline to 100.39 points, down 4.83% month on month.
