MANUFACTURING DEVICE AND MANUFACTURING METHOD FOR HOT-ROLLED STEEL STRIP

摘要

In order to provide a manufacturing device and a manufacturing method for a hot-rolled steel strip, which are capable of obtaining the desired quality of material by rapid uniform cooling immediately after rolling, and improving yield by early sheet tension and sheet shape measurements, a manufacturing device for a hot-rolled steel strip is provided with a finishing rolling mill line (11), a first cooling unit (13) installed just behind the exit side of the finishing rolling mill line, and a pinch roll (14) which is installed on the exit side of the first cooling unit and in contact with both the upper and lower surfaces of a strip (S), at least a draining roll (15) located on the upper side of the strip (S) is disposed between the first cooling unit and the pinch roll, and a tension/shape measuring unit (16) for measuring the tension and shape of the strip (S) is installed between the draining roll and the pinch roll.
