Production method for controlling shape of X80 pipeline steel plate

The invention relates to a production method for controlling the shape of a steel plate of pipeline steel, which comprises the following steps of: 1, rolling by using a positive bending roller, namely rolling by using the positive bending roller in a controlled rolling process, so that a rolled piece has the characteristic that two sides are thick and the middle is thin after being rolled; (2) the finish rolling temperature is controlled, specifically, the water inlet temperature is controlled within the range of Ar3 +/-(0-20) DEG C; in the finish rolling stage of controlled rolling, the temperature waiting thickness of the rolled piece is controlled to be not higher than 3.7 h, and h is the finished product thickness of the rolled piece; and fourthly, finish rolling control is conducted, specifically, finish rolling is non-recrystallization zone rolling, a small reduction rate is adopted for 2-3 passes after finish rolling, the reduction rate of a single pass is not larger than 10%, and the reduction rate gr
