Development of Oxide Metallurgy Technology in Baosteel
The industrial technology of oxide metallurgy has been developed by Baosteel.With delicate control of the vital elements in steel,deoxidation and continuous casting process,the desired micro-meter inclusions and the nano-meter precipitates in the steel plate can be effectively controlled.In the heat affected zone of the steel plate after high-heat input,the formation of coarse grain zone can be effectively inhibited,and the growth of intragranular ferrite can be greatly promoted.After two-electrode Vibratory ElectroGas Arc welding(VEGA) with the V-type groove and the high-heat input of 400 kJ/cm in single pass,excellent heat affected zone toughness can be obtained for the steel plates with the thickness up to 68 mm.
