Claims12
A modular spray bar system (1) for selectively cooling and/or lubricating rolls and/or rolled material in a rolling mill, comprising
- different blocks, including
- at least one central connection block (1) having at least one first fluid connection (3),
- wherein the at least one first fluid connection (3) opens into a first through bore (4) extending in the direction of a spray bar axis,
- wherein the first through bore (4) forms a part of a first fluid channel (45) of a spray bar (47), and
- wherein at least one first transverse bore (6) extends transversely from the first through bore (4) and opens into a first fluid outlet opening (10, 11);
- at least two central extension blocks (20) connectable to the central connection block (1),
- wherein each of the central extension blocks (20) has a first through bore (21) extending in the direction of the spray bar axis, the first through bore (21) forming a part of the first fluid channel (45) of the spray bar (47), and
- wherein at least one first transverse bore (23) extends transversely from the first through bore (21) and opens into a first fluid outlet opening (25);
- at least two outer extension blocks (30) connectable to the central extension blocks (20),
- wherein each of the outer extension blocks (30) has a first through bore (31) extending in the direction of the spray bar axis, the first through bore (31) forming a part of the first fluid channel (45) of the spray bar (47), and
- wherein at least one first transverse bore (33) extends transversely from the first through bore (31) and opens into a first fluid outlet opening (35);
- at least two outer connection blocks (40) connectable to the outer extension blocks (30), each having at least one second fluid connection (41),
- wherein the at least one second fluid connection (41) opens into a first blind bore (43) that is closed on one side and extends in the direction of the spray bar axis, the first blind bore (43) forming an end part of the first fluid channel (45) of the spray bar (47), and
- at least one brace by which the spray bar (47) formed from the blocks can be braced.
