Abstract (en)
[origin: WO2020187749A1] The invention relates to a flat rolled material (1) made of metal, which flat rolled material is conveyed on a conveying path in a transport direction (x). A device for cooling the flat rolled material (1) by means of a liquid coolant (5) has at least one cooling bar (3), which is arranged above the conveying path and to which the liquid coolant (5) is fed via a supply line (4). The cooling bar (3) extends substantially perpendicularly to the transport direction (x) and has a plurality of outlet tubes (6), which in turn each have an inlet opening (7) and an outlet opening (8). The liquid coolant (5) enters the outlet tubes (6) from the cooling bar (3) via the respective inlet openings (7) and exits the outlet tubes (6) via the respective outlet openings (8). Each outlet tube (6) has, in the flow direction of the liquid coolant (5), an initial portion (9), which proceeds from the inlet opening (7) and extends upward, a middle portion (10), which adjoins the initial portion, and an end portion (11), which adjoins the middle portion, extends downward and extends to the output opening (8). The middle portion (10) therefore contains a vertex (12), at which the coolant (5) flowing through the outlet tube (6) in question reaches a highest point. The outlet openings (8) are located above the cooling bar (3). A height distance (h1) of the inlet opening (7) from the vertex (12) is at least twice as large, in particular at least three times as large, as a height distance (h2) of the outlet opening (8) from the vertex (12).
