| 摘要 |
The present invention relates to a device and a method for controlling the conveying speed of a cooling unit to improve the winding properties of a hot-rolled steel plate, the conveying speed of a cooling unit, and productivity by increasing the conveying speed of a cooling unit when the rear end of a hot-rolled steel plate is coming out from a rolling mill after a hot-rolling process to be wound through the cooling unit and preventing the front end of the hot-rolled steel plate from being overcooled. [Reference numerals] (AA) Time;(BB) Speed increase rate (%);(CC) Speed;(DD) Start to wind the front end;(EE) End to roll the rear end;(FF) End to roll the front end |
