| Abstract: | The development of hot rolled strip for X52 pipeline conveying oil or natural gas in Angang is described. This steel grade is Nb-Ti microalloying. The molten iron pretreatment, vacuum treatment and refining are adopted in smelt process to increase the steel cleaness. The calcium treatment is used to change the sulfide morphology. The CC billets are substituted for mould casting billets to reduce the composition segregation of steel.The steel is rolled in 1780 line. The batch production shows X52 grade has the features of high cleaness and high toughness, the product quality is excellent and the performance is stable. |
