Abstract
Description
- 1. Field of the Invention
- The invention relates to a water cooling stretch for cooling rolling stock such as wire or small sections of steel coming from by a roll train, wherein the water cooling stretch comprises several adjacently positioned cooling pipes which have different inner diameters matching the different cross-sections of the rolling stock and which form a cooling pipe arrangement, respectively, comprised of several pipe sections arranged in a straight succession. They are arranged together on a support, movable horizontally and transversely to the movement path of the rolling stock, and can be moved as needed into and out of the movement path, wherein the cooling water supply to the individual cooling pipe sections is realized by cooling head nozzles and correlated inflow-controllable valve arrangements.
- 2. Description of the Related Art
- Devices of the aforementioned kind are described, for example, in German patent application DE 199 60 638, not published as of the priority date of the instant application for patent. This document describes a water cooling stretch comprised of several parallel and adjacently positioned cooling pipes with different inner diameters arranged on a transversely movable support configured for moving the cooling pipes into and out of the movement path of the rolling stock. These cooling pipes are arranged with the support in a water box and have a common cooling head arranged at its inlet openings and comprising several correspondingly sized nozzles for the cooling water correlated with the cooling head. These nozzles have arranged upstream thereof a rotary slide valve which supplies a nozzle which is currently in a working position with cooling water, respectively. Instead of this rotary slide valve, as explained in more detail later on in this document, other control devices, for example, regulating flaps, slide valves or individual valves can be used. This configuration has the disadvantage that the exchange of cooling pipes and of the cooling heads and control devices connected therewith entails a considerable constructive expenditure and requires experienced personnel for the exchange procedure.
- It is an object of the present invention to decrease the constructive expenditure for water cooling stretches of the aforementioned kind and to simplify their operation.
- In accordance with the present invention, this is achieved in that the inlet and outlet openings of the individual cooling pipe sections of the cooling pipe arrangement open into independent water box modules which together are arranged fixedly on a water supply pipe which forms the horizontally movable support.
- Based on the discussed prior art, which is an application filed by the instant applicant, according to which a series of cooling pipe sections is arranged successively in a common cooling water box and cooling heads, which are secured by threaded securing elements, are connectable with the inlet openings of the individual cooling pipe sections, wherein the water supply of the cooling heads is realized by separate supply pipes and by high-speed switching valves provided external to the water box, the aforementioned object is solved according to the invention in that the inlet and outlet openings of the individual pipe sections of the cooling pipe arrangement open into individual water box modules which are arranged together fixedly on a water supply pipe which forms a horizontally movable support. In this connection, in each one of the water box modules individual independent cooling head nozzle elements can be used which are exchangeable between the openings of the respective pipe sections of the cooling pipe arrangement and connectable with correlated high-speed switching valves. In the water box modules arranged at the beginning and the end of the water cooling stretch it is possible to provide blow nozzle elements, arranged so as to be exchangeable also, upstream or downstream of the cooling head nozzle elements, and, moreover, these water box modules can comprise adjusting or control elements for adjusting the cooling head nozzle elements and the blow nozzle elements. The water box modules have expediently a pivotable and lockable cover in which clampable securing elements for the cooling head nozzle elements and the blower nozzle elements are arranged. Moreover, in the water box modules pneumatically or hydraulically actuated high-speed switching flaps can be provided which are connected with the water supply device.
- This configuration according to the invention of the water cooling stretch makes it possible to demount and exchange the cooling head nozzle elements provided within the individual water box modules and also the blow nozzle elements without difficulty. Also, the pipe sections arranged between the water box modules can be demounted and exchanged without problem. Since the individual cooling pipe arrangements can be moved by transverse movement of the support pipe into and out of an operating position and each one can be individually supplied with cooling water by the high-speed switching valves, such exchange operations require only short interruptions of the rolling operation supplying the rolling stock.
- In the drawing:
- FIG. 1 is a water cooling stretch in a longitudinal section viewed from the side;
- FIG. 2 is a plan view onto a portion of the water cooling stretch in a horizontal section on an enlarged scale; and
- FIG. 3 is a section along the line A-A of FIG. 1 on an enlarged scale.
- In FIG. 1 it is shown that water box modules WKM, in the disclosed embodiment four such modules, are positioned at a spacing to one another on the water supply pipe WZR and are fixedly connected thereto in a way not illustrated in more detail. The water supply pipe WZR rests with slide supports ST, horizontally moveable in the direction of double arrow P (see FIG. 2), on stationary foundations F and can be moved in a way not illustrated by means of cylinder devices or other adjusting or advancing elements in a horizontal plane. Cooling pipe sections are arranged at a spacing adjacent to one another in a horizontal plane at the neighboring water box modules WKMa, WKMb, WKMc, and WKMd. In the illustrated embodiment three such pipe sections, respectively, are provided. In FIG. 2, they are identified by KRA1, KRA2, KRA3. They are secured by the sidewalls SW of the respective water box module WKM. They have different inner diameters d1, d2, d3 and project with their openings M1, M2, M3 into the water box module WKM.
- High-speed switching valves SSV1, SSV2, SSV3 are arranged in the water box modules (compare FIG. 3) and are supported on the water supply pipe WZR. Cooling head nozzle elements KDE1, KDE2, KDE3 can be placed in an exchangeable way onto the switching valves and can be fastened, in a way not illustrated, by means of pneumatically or hydraulically actuated cylinder devices, springs, wedges or even with screws in a detachable way, or, as illustrated, can be clamped by a clamping element SP which is connected to the cover AD that is pivotably connected to the water box module WKM. In the water box modules WKMa and WKMb at the beginning and the end of the water cooling stretch, blow nozzle elements BLE1, BLE2, BLE3 can be used in addition to the cooling head nozzle elements KDE1 and KDE2 and are arranged upstream or downstream thereof. They are also exchangeably mounted and can be secured in the same way as described above for the cooling head nozzle elements KDE. These cooling head nozzle elements and the blow nozzle elements, after having been mounted, can be adjusted in a way not illustrated by means of threads and guides or clamping nuts against stops. Moreover, pneumatically or hydraulically actuated high-speed switching flaps for suppressing pressure peaks of the water supply pipe WZR can be arranged in the water box modules WKM.
- While specific embodiments of the invention have been shown and described in detail to illustrate the inventive principles, it will be understood that the invention may be embodied otherwise without departing from such principles.
