DEVELOPMENT OF HIGH HEAT INPUT WELDING HIGH STRENGTH STEEL PLATE FOR OIL STORAGE TANK IN XINYU STEEL COMPANY
This essay introduces the developed high-heat input welding quenched and tempered pressure vessel steel 12MnNiVR for oil storage tank by Xinyu Steel,which passed the review by the Boiler and Pressure Vessel Standards Technical Committee in 2009.The review comments that compared to the domestic and foreign similar steel standard,the key technical index of enterprise standard were in advanced level.After the heat input of 100kJ/cm electro-gas welding,welded points were still with excellent low temperature toughness at-20℃.The steel plate may be constructed for oil storage tank,which has been permitted by thickness range from 10 to 40mm,and design temperature among-20℃-100℃.It studied microstructure genetic effects mechanical properties of the steel.Many production practices indicated that the mechanical properties of products and the steel by stress relief heat treatment of steel were excellent,with pretreatment of hot metal,converter refining,external refining,protective casting,TMCP and heat treatment process measurements.The stability of performance and matured technology of Xinyu Steel support the products could completely service the demand of steel constructed for 10-15 million cubic meters large oil storage tank.
