description The invention discloses a rolling control method of four-time-length pipeline steel, and relates to the field of pipeline steel rolling. The rolling control method comprises the steps that (1) a plate assembling manner is adjusted, four-time-length plate assembling is achieved, and the technological process comprises the steps of heating, TMCP rolling, cooling, straightening, warm straightening and finishing shearing; (2) a hot straightening signal is modified, a steel plate is not decelerated when coming, the hot straightening speed is the same as the speed of the steel plate and an ACC roller way, the steel plate normally passes, the length from an ACC outlet to hot straightening is smaller than the length of the steel plate, the steel plate decelerates before hot straightening, the tail of the steel plate stops at ACC, and a hot straightening model is shielded and changed into roller way idling; (3) the speed of the roller way after hot straightening is modified, and the speed of the steel plate and the sp
