Definitions
- the invention relates to methods and a cooling device for cooling the Wa zen, in particular the work rolls of a rolling mill.
- the rollers involved in the rolling process are heated. To protect them from damage and to obtain as long as possible, the rollers are cooled.
- Cooling systems are nowadays used in most rolling mills, which spray a cooling liquid onto the roll surface with the aid of nozzles (preferably flat-jet nozzles). Such cooling is referred to as spray cooling.
- the selected pressure level is between 6 bar and 12 bar and, in exceptional cases, 20 bar.
- the work roll cooling is intended to keep the roll free of dirt, oxide and scale particles.
- the cooling effect increases with higher coolant quantity and increasing coolant pressure. Disadvantage of the system is that it requires a large amount of energy and at higher pressure, the maintenance of the pump is more complex.
- WO 2008/104037 A1 discloses a cooling device with highly turbulent cooling in the low-pressure region, in which a roll is cooled by means of nozzles or bores arranged on a concave cooling beam.
- the cooling device works satisfactorily and reproducibly only when the diameter range of the roller resulting from the grinding is matched to the curvature of the cooling device.
- the number of cooling devices required for different roller diameters which necessitates a sophisticated roller logistics, is necessary.
- a low pressure cooling in the form of a flow cooling is described in DE 36 16 070 C2, wherein in a defined relatively narrow gap between the work roll surface and a cooling shell, the cooling liquid is guided in a directed manner and with external pressure on the roll surface.
- the pressure level is lower and depends on the gap width and flow speed. Higher cooling effects are achieved here by higher flow velocities. Due to the lower pressure level, the system has no cleaning effect on the roll surface.
- a disadvantage of this device is that a separate cooling block is necessary for each roller, since this is mounted on the roll chocks. For a conventional hot rolling mill, therefore, a large number of these cooling blocks is required.
- the adaptation of the gap width to different work roll diameter and the consequences of the cooling block of the respective work roll position has also proved to be disadvantageous or very complicated, since the adjustment of the gap must be done manually and outside of the rolling mill.
- the object is procedurally achieved with the features of claim 1 and device according to the features of claim 24 solves that the rolls are also subjected to high pressure cooling at the same time as the low pressure cooling, the rollers in the high pressure cooling directly with a high pressure Be sprayed coolant.
- the cooling liquid can be taken from a high tank, for example 7-12 m high, or generated directly by low-pressure pumps.
- the required pressure range for the cooling liquid of the low pressure roller cooling is dependent on the thermal load of the rollers and is between z. 0.5 to less than 5 bar.
- a spray cooling, coolant curtain, gap cooling or flow cooling, highly turbulent cooling ( Figure 2) or a combination of the various low-pressure systems can be used.
- a single-row or double-row spray jet bar can be used, as in conventional systems.
- the small amount of cooling liquid of about 20% of the total amount of cooling liquid is sufficient for this task, wherein a pressure range for the cooling liquid between 5 - 50 bar, preferably 12 bar is required.
- the pressure range used for the cooling fluid of the high-pressure roller mill depends on the rolling parameters thickness reduction, specific surface pressure in the roll nip, rolling speed, strip temperatures, roll material and rolled material.
- the pressure level can be increased accordingly. Through a camera, the roll surface can be observed to derive therefrom the pressure level change. Furthermore, in order to influence the oxide layer thickness on the roll, the pressure level can be adjusted individually in steps (for example by switching on or off of pumps) or steplessly.
- the combined low-pressure high-pressure cooling is provided for example for the front stands of a hot strip mill. In the rear scaffolds, a pure low-pressure cooling can then be used.
- the high pressure chilled beam can operate over almost the entire length of the bale or be movable in the width direction and with a localized cooling effect. If only a simple low-pressure shell cooling is used in an application, then a combination with the cooling according to the Japanese patent application JP 07290120 is conceivable and provided. Here, with the help of an engine, two spray nozzle beam sections are moved axially or in the width direction, and the work roll is locally cooled differently.
- an electric or hydraulic motor with threaded rod or two motors for separate adjustment on the left and right side are preferably alternatively a hydraulically moving single or multi-link articulated rocker with spray bars mounted thereon or rotatable nozzle units executable to the coolant jets on the desired areas of Ar - to steer the work roll (inside or next to the belt area) in order to positively influence the belt profile and the flatness.
- Analogous to the embodiment with the spraying in the width direction spray bar sections for example, for a segment of the low-pressure shell cooling short segmental shell parts with a width of, for example 150 mm axially adjustable in the width direction and be executed only locally (eg symmetrically at two points of the work roll) acting.
- the low-pressure work roll cooling used in the invention has the task optimally and efficiently to cool, despite the lowdefact- keitstik the cooling effect (heat transfer from the roller to the cooling liquid) should be high. This causes a lower roll temperature or can be used to reduce the amount of cooling liquid.
- a flow cooling is preferably used, in which the cooling liquid is conducted past the roll surface in a relatively narrow gap between the work roll and an arc-shaped cooling shell.
- the cooling device consists essentially of articulated interconnected movable cooling shell segments.
- three, but usually two cooling shell segments are used. In special cases, however, only one cooling shell segment can be used.
- the individual cooling-cup segments preferably have joints or joint halves laterally or at their ends. At least one pivot point is present on the middle cooling-plate segment, which receives at least one, preferably two, cylinders (hydraulic or pneumatic cylinders).
- the cylinders have their second breakpoint on the other members of the adjacent cooling shell segments.
- the cylinders can be arranged in the middle of the cooling beam or at the edges on both sides. Instead of adjusting the shells with cylinders, an adjustment with, for example, hydraulic motors or electric motors is conceivable.
- the console or the cooling beam support with mounting holes.
- the position adjustment is carried out with a multi-link linkage, which is operated pneumatically, hydraulically or electromechanically.
- the cylinders have position measuring systems and pressure transmitters.
- the position of the cylinders and thus the gap setting or distance determination between cooling shell segment and roller as well as the monitoring of the set positions can be determined and carried out in the following different ways, whereby a combination of the mentioned methods is possible:
- the calibration process of the cooling system may be performed during the framework calibration procedure.
- the gap can be measured directly and the cylinders and linkages adjusted accordingly with a control system.
- the cooling device according to the invention adapts to the respective roll diameter and roll positions due to the existing hinge mechanisms, since the adjustment systems of the cooling beams are connected to the thickness control and follow the vertical movement of the work rolls, for example in the case of a thickness changeover.
- the cooling shells are automatically pivoted back slightly.
- the cooling device forms in a constructive Austechnologyu ⁇ gsform using a sealing function a space from which only a small amount of cooling liquid enters the environment.
- the seal is made by conditioning the shell at the top and bottom of the work roll, which can be pressed with a predetermined pressure and / or by applying a dynamic pressure on the edge of the cooling shells. This arrangement makes it possible to form an almost closed cooling circuit.
- the cooling bars can be fixed with cooling shells and conventional high and / or low pressure spray bars.
- a gap is formed through which the coolant flows.
- the gap widths between the cooling shell and the work roll are adjusted in a targeted and reproducible manner during operation, independently of the roll diameter, between 2 and 40 mm, for example to 5 mm.
- the gap between the work roll and the cooling shell can be approximately equal to -tangential- or the shell is made narrowing toward the outlet.
- the sectional flow cooling is divided into sections.
- the cooling liquid flows from an example funnel-shaped rectangular slot in the individual areas of the cooling shell against the roller and is deflected to both sides (up or down) or only primarily to one side, the cooling shell enforces a flow along the roller.
- the cooling liquid absorbs the heat of the roller efficiently.
- the heated coolant then flows backwards making room for new cold coolant.
- the chilled beams are designed in such a way that the cooling liquid flowing to the rear (away from the roller) can flow off well, especially on slopes.
- baffles the returning coolant on the upper side is additionally directed to the side in order to reduce the pool effect over the wiper.
- the individual cooling areas are separated from each other by mutual shielding, so that the cooling liquids of the adjacent cooling bars hardly interfere with each other.
- the cooling liquid In a continuous flow cooling, the cooling liquid is passed over a larger contiguous angular range of the roller. A low adaptable gap width and high flow velocity are required to produce good heat transfer. The gap width and cooling liquid quantity must therefore be coordinated.
- the contiguous flow cooling can be operated in countercurrent or DC-current principle. Due to the long path between inlet and outlet side, a lateral sealing of the cooling shell is required.
- an operating mode can also be carried out in which the cooling liquid is supplied to the upper and lower cooling beam pipelines. The process is then targeted to the pages. In this principle, first the cooling fluid flowing tangentially to the roller decreases

- FIG. 1 shows a prior art spray cooling in which a cooling liquid 7 is sprayed by means of nozzles 27 onto the roll surface of the work rolls 1, 2. Due to the relatively large distance between the nozzle and the roller, a higher coolant pressure range (eg 6 ... 15 bar) is selected. Inlet and outlet side arranged scrapers 17 ensure that as little as possible cooling liquid can come into contact with the rolling stock 4.
- FIG. 2 shows another known possibility for cooling the work rolls 1, 2. This is a highly turbulent cooling in the low pressure range. Water is sprayed onto the roll surface of the work rolls 1, 2 with the aid of nozzles 27 arranged on the inlet side and through the holes introduced in the concavely curved contiguous cooling shell 11, and a water cushion with a turbulent and undirected flow is formed in front of the work roll.

- the hinge axis of the articulated connection is preferably parallel to the longitudinal axis of the roller.
- the cooling liquid 7 flows in countercurrent to the rolling direction 5 in the gap 30 to then flow through the outlet opening 24 and the discharge pipe 26 again. If the discharge pipe 26 or the outlet opening 24 is closed or not carried out in a special case, it is possible to selectively generate a coolant discharge transverse to the roll. Side seals are then only partially available here.
- the segment lengths of the cooling-cup segments 13 forming the gap 30 should be approximately the same, so that, as the diameter of the work-roll 1 changes, the cooling-cup segments 13 can follow the change in curvature of the roll-coated surface 6 optimally.
- the individual cooling-cup segments 13 have at their ends joints or joint halves which, connected to one another, form a corresponding number of pivot pivots 22 and pivot points 21 which are connected to one another by cylinders 20, for example hydraulic or pneumatic cylinders.
- the cooling-beam support 16 is provided with an articulation point 23, by means of which it is possible to join the cooling-plate segments 13 and all components connected thereto in the illustrated (horizontal, vertical and rotational) adjustment directions 45 of the cooling beam support to move a multi-link linkage, not shown here.

- the supply pipes 25 for the low-pressure liquid refrigerant ND to be used 7 are here each at the upper and lower cooling cup segment 13, so that here thedestattkeitsteilmengen in countercurrent and cocurrent, with respect to the Waizencardraum 5, are guided through the gap 30.
- the flow directions are indicated by arrows 43.
- the upper and lower edges of the cooling shell 11 are formed with a contact surface 46, for example a hard tissue plate, which is sealingly guided against the roll shell surface 6.

- high pressure (HD) nozzles are arranged in this embodiment, by means of which the low-pressure high-pressure cooling combined according to the invention is realized.
- the high-pressure spray bar can be arranged separately on the cooling beam carrier 16 or attached to a cooling shell segment, so that it can be adjusted with it.
- cooling shells of a flow cooling region can also be divided into two, so that the outlet opening 24 is slightly displaced by relative displacement and subsequent fixing of the two halves is adjustable. Furthermore, slightly different shell thicknesses or gap widths per cooling beam can be set and the amount of coolant flowing upwards and downwards can be influenced.
- the cooling beam support 16 is positioned with the middle cooling shell segment 13 in front of the roller.
- the other two cooling-plate segments 13 are placed against the work rolls 1, 2 with the aid of a straight or curved cross-bar 48 which can be rotated in a small defined area with a corresponding spring contact pressure of the spring 8.
- coil springs 8 with corresponding holders can be attached to the ends.

Also, it is then advantageously possible to use rigid spacer bars instead of movable cylinders 20.
- the gaps between the roller and the cooling pan then vary slightly, depending on however, the section-wise flow cooling system is still effective and the system is easier to manufacture. It must only be positioned depending on the work roll diameter and the work roll position in front of the roller so that the gap optimally, so the outlet openings are arranged relatively close in front of the roller depending on the work roll diameter.
