| description | The invention relates to the technical field of steel materials, in particular to a titanium microalloy strengthened pipeline steel hot-rolled coiled plate and a production method of the titanium microalloy strengthened pipeline steel hot-rolled coiled plate. The production method of the titanium microalloy strengthened pipeline steel hot-rolled coiled plate comprises the working procedures of pretreatment of molten iron, top-bottom combined blowing converter processing, LF refining, double-strand slab continuous casting, steel rolling carried out through a hot continuous rolling mill, laminar cooling and coiling. The production method of the titanium microalloy strengthened pipeline steel hot-rolled coiled plate is characterized in that during LF refining, the tapping temperature is 1630-1690 DEG C, and the steel smelting components are controlled to include, by weight, 0.06%-0.09% of C, 0.80%-1.50% of Mn, 0.10%-0.30% of Si, not larger than 0.010% of S, not larger than 0.025% of P, 0.035%-0.060% of Ti, not l |
