Abstract: Given the low cooling capacity and the poor uniformity of conventional accelerating cooling control (ACC), ultra fast cooling (UFC) equipment was developed. With closer distance between the nozzles of the UFC equipment and the plate, cooling water sprayed with a high pressure at a proper angle along the rolling direction can clear away the vaporous film forming on the plate, thus making the water cover the plate completely and achieving nucleate boiling. Using the UFC equipment, cooling efficiency and uniformity are improved significantly and pipeline steels are developed at a low cost. Compared with the ACC, the UFC can greatly reduce both the alloy content in pipeline steels and the defective rate of plate shape.
