METHOD AND EQUIPMENT FOR MANUFACTURING HOT-ROLLED STEEL STRIP

摘要

PROBLEM TO BE SOLVED: To prevent the generation of excessive displacement upward from the pass line and nose break, tail end break or the like due to the displacement by making a hot-rolled steel strip stably run on a run out table. SOLUTION: By jetting a fluid jet stream so as to pass through the upper part of the hot-rolled steel strip without contacting with the surface of the hot-rolled steel strip which is passed through on the pass line ( provided the steel strip conveying face of the run out table ) and making the steel strip part where is upward displaced exceeding a prescribed level from the pass line collide against the fluid jet stream, the displacement in this steel strip part is straightened. The displacement of the steel strip by the fluid jet stream is also suitably prevented because the fluid jet stream is passed through the upper part of the steel strip perfectly without contacting with the hot-rolled steel strip which is normally passed through.
