Abstract (en)
[origin: EP2353742A1] The hot rolling mill (1) comprises a cooling section (4) for cooling the hot strips, and strip driving devices arranged in a mass flow direction after the start of the cooling section and in mass flow direction before the end of the cooling section, where a tensile stress of the hot strips is adjustable by the strip driving device. Two adjacent strip driving devices have an interval f 20-50 m. The cooling section has cooling segments (5) releasing a cooling agent spaced apart from each other in the mass flow direction. The strip driving device is formed as a set of driving rollers. The hot rolling mill (1) comprises a cooling section (4) for cooling the hot strips, and strip driving devices arranged in a mass flow direction after the start of the cooling section and in mass flow direction before the end of the cooling section, where a tensile stress of the hot strips is adjustable by the strip driving device. Two adjacent strip driving devices have an interval f 20-50 m. The cooling section has cooling segments (5) releasing a cooling agent spaced apart from each other in the mass flow direction. The strip driving device is formed as a set of driving rollers, where the strip driving device is arranged between all the adjacent cooling segments. A further strip driving device is arranged upstream and/or downstream to the cooling section in the mass flow direction. Independent claims are included for: (1) a method for operating a hot rolling mill; and (2) a control- and/or regulating device for a hot rolling mill.
