The predecessor of Ningbo port is Ningbo Port Authority. Ningbo port consists of Beilun port, Zhenhai port, Ningbo port, Daxie port and Chuanshan port. It is a multi-functional and comprehensive modern deep-water port integrating inland river port, estuary port and seaport.
Weathering steel generally adopts the process route of fine material into the furnace-smelting (converter, electric furnace-microalloying treatment-argon blowing-LF refining-low superheat continuous casting (feeding rare earth wire)-controlled rolling and cooling. The scrap steel is added into the furnace together with the charge, and smelted according to the conventional process. After the A588 Gr A structural steel plate steel is tapped, deoxidizers and alloys are added. After the molten steel is treated with argon blowing, the molten steel is cast. By adding rare earth elements to the steel, the A588 Gr A structural steel plate weathering steel is purified and the content of inclusions is greatly reduced.
The Qatar Railways company launched a tender for designing ,construction and completion of Green Line Project. Our company has participated in the bidding from Qatar Railway Company since May, 2016. A delegation from project visited several famous A588 Gr A structural steel plate pipe mill in China for 15 days in July,2016. Of course the delegations had visited our pipe mill.
