Description
Technical Field
[0001] The utility model relates to the technical field of cooling devices, in particular to an adjustable cooling device used for roughing and intermediate rolling. Background Art
[0002] High-speed wire rod is one of the more mature steel production capacities in China. Generally, the rolling of high-speed wire rod is organized by full continuous rolling. The billet is first heated in a heating furnace. After the billet reaches the heating temperature, it is taken out of the furnace and sent to the rough rolling group composed of 5-8 short stress lines and two-roll rolling mills arranged alternately horizontally and vertically through a roller table for rolling. After the rolled piece leaves the rough rolling mill group and passes through the flying shear head, it enters the intermediate rolling mill group composed of about 8 short stress lines and two-roll rolling mills arranged alternately horizontally and vertically for further rolling.
[0003] The rolled pieces exit the intermediate rolling mill through a guide tube and enter the cantilever roller ring pre-finishing mill with four frames arranged alternately horizontally and vertically. Vertical loopers are installed between the frames of the pre-finishing mill to perform tension-free and torsion-free rolling on the rolled pieces.
[0004] The rolled pieces from the pre-finishing mill are cooled by the intermediate water tank to ensure the required temperature of the rolled pieces before entering the finishing mill. Then, they are sent to the non-twisting finishing mill through the flying shear head and the side looper. After the final rolling, they are cooled by the water tank and spit out by the pinch roller and the laying head. They are cooled by the cooling roller and transported to the coiling device. After the heads and tails are cut, they are packed and stored, completing the entire rolling process.
