Definitions
- the invention relates to a device for cooling rolling stock within the cooling section of a rolling mill, in particular for a hot strip rolling mill, in which water spraying devices are arranged underneath the rolling stock between rollers of a roller table and spray bars held above the rolling stock on supporting levers, the supporting levers being parallel to one another the longitudinal axis of the roller table extending, tubular, rotatable and water-fed swivel tube are carried, with a central water supply pipe and a control and regulating device with associated switching valves for switching the cooling water on and off.
- Devices for cooling rolling stock form an integral part of every rolling mill; They have become increasingly important since certain metallurgical states, for example grain sizes, have been influenced by influencing the transformation of the steel, and the associated high load capacity of the rolled product has been sought.
- FIG. 1 shows a longitudinal section through the compact design of a cooling system with a transport roller table, belt guide and belt longitudinal spray,
- FIG. 4 shows a top view of a section of the roller table with an arrangement for the belt guide
- FIG. 5 schematically, in vertical section, a spray bar with a spray tube plate and spray tubes
- FIG. 2 is kept on a larger scale and represents a cross section through the roller table 1 in the central plane of a lower chilled beam.
- the cooling beam 2 can be seen, which is closed at both ends by, for example, removable flaps 7 for cleaning.
- the cooling beam 2 is fed by a cooling water pipe 8 via a bend 9.
- the rollers 10 of the roller table 1 are equipped with long, slim pins 11 which support the rollers in bearings and transmit the drive from the roller table motors 12.
- the rollers 10 are provided in a very narrow division and in the formed between them narrow column still engage the spray tube 13 of the chilled beams 2. However, this allows only small amounts of cooling water to flow between the rollers 10; the more space to drain them off between the long, slim pins 11 of the rollers 10.
- the belt guide rulers 6 are shown again: The ruler shown on the left is retracted for maximum belt widths or a rest position and thus releases the area of the pins 11 of the rollers for the outflow of water from the beginning.
- the ruler shown on the right is extremely advanced for a minimal bandwidth and thus largely covers the run-off path formed between the pins 11 of the rollers 10.
- the tape guide rulers 6 will therefore be adjusted according to the width of the incoming tape when the tape runs in, and after running in, both switch on the cooling and pull the tape guide rulers back into their rest position of the maximum opening.
- FIG. 5 shows an enlarged cross section. Shown is a spray tube 4 that engages under the spray bar 3 and a number of spray tubes 20. As the enlarged, drawn-out representations show, the free mouth region 21 of the spray tubes 20 that receives the cooling water is widened in a funnel shape in order to be able to absorb the inflowing water without throttling.
- the outlet area 22, on the other hand, is either cylindrical or drawn in, usually only slightly, to the extent required to achieve the desired spraying speed.
- the spray tubes 20 can be fastened in the spray tube plate 4 or, if a change or exchange is necessary for reasons of wear, but also for reasons of the use of other dimensions, they can be exchanged.
- the nozzles are located close to the wall surface, so that an effective jet effect is ensured.
- the flaps protect the nozzles and can avoid malfunctions, such as loop formation, in the event of a belt run, without causing significant damage to the devices for longitudinal spraying.
