Abstract
The utility model relates to a steel rolling water cooling device before the pre-splitting, which comprises an inlet guide device, an inlet seat and a nozzle, wherein the inlet guide device with a square horn mouth, the inlet seat, the nozzle and a water inlet tank are sequentially arranged from left to right; a middle pipe is arranged between the water inlet tank and a return water tank; a plurality of square cooling elements are tightly distributed in the middle pipe, and a plurality of small holes are uniformly distributed on the square cooling elements; and the upper end of the return water tank is provided with a water outlet pipe, and the right side of the return water tank is provided with an outlet guide device which is communicated with a blowback device. The steel rolling water cooling device before the pre-splitting has a compact structure and adopts a mode of cooling by water with certain pressure and spraying up and down by the nozzle, so that rolled pieces can be better float in the device, the rolled pieces can be uniformly cooled, the ambient temperature of the rolled pieces is uniform, and the product quality and the timber production rate of the rolled pieces are effectively improved.
Description
Technical field: the utility model relates to steel rolling temperature-controlled rolling device, particularly relates to the preceding water-cooling device for rolling steel of pre-cutting in the rolling device.
Background technology:, all the temperature-controlled rolling device can be installed on the rolling line in the more advanced country of steel rolling industry.Can improve the surface quality and the mechanical property of rolled piece on the one hand, avoid rolled piece at high temperature to be exposed in the air on the other hand and can form thicker oxide film, can effectively improve the product quality and the lumber recovery of rolled piece; The temperature-controlled rolling device is installed at domestic traditional steel rolling industry or small section rolling mill industry end, so unstable product quality, productivity ratio is low, is steel rolling field problem demanding prompt solution.
Summary of the invention: the purpose of this utility model is exactly the water-cooling device for rolling steel that will provide a kind of pre-cutting preceding, and it can solve installation temperature-controlled rolling device existing problem in end on the present rolling line.The purpose of this utility model is to realize like this, water-cooling device for rolling steel before the pre-cutting, comprise that import guide and guard, inlet port, nozzle form, it is characterized in that: be disposed with from left to right and be with square bell-mouthed import guide and guard, inlet port, nozzle, inlet water tank; Between inlet water tank and recovery tank, be provided with intervalve, closely be placed with several square cooling elements in the described intervalve, uniform several apertures that is provided with on the square cooling element; Described recovery tank upper end is provided with outlet pipe, and right-hand member is provided with outlet guide, and outlet guide communicates with back-blowing device.The utility model compact conformation, the intensity height, employing has the water cooling of certain pressure and the mode that nozzle sprays up and down, make rolled piece well to float in the device, rolled piece can cool off uniformly, the back rolled piece temperature on every side of rising again is more even, helps splitting rolling, effectively raises the product quality of rolled piece and the productivity ratio of becoming a useful person.
Description of drawings:
Fig. 1 is the utility model structural representation;
1. guide groove, 2. travelling car, 3. import guide and guard, 4. inlet port, 5. nozzle, 6. inlet water tank, 7. intervalve, 8. square cooling element, 9. recovery tank, 10. outlet pipe, 11. outlet guides, 12. back-blowing devices.
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing:
Water-cooling device for rolling steel before the pre-cutting comprises that import guide and guard 3, inlet port 4, nozzle 5 form, and it is characterized in that: be disposed with from left to right and be with square bell-mouthed import guide and guard 3, inlet port 4, nozzle 5, inlet water tank 6; Between inlet water tank 6 and recovery tank 9, be provided with intervalve 7, closely be placed with several square cooling elements 8 in the described intervalve 7, uniform several apertures that is provided with on the square cooling element 8; Described recovery tank 9 upper ends are provided with outlet pipe 10, and right-hand member is provided with outlet guide 11, and outlet guide 11 communicates with back-blowing device 12.During concrete enforcement, the utility model is arranged on the travelling car, square or the I-shaped die rolled piece that high temperature comes out from pre-finishing mill, enter the import guide and guard by guide groove, cooling water by inlet water tank by the surface of nozzle ejection to rolled piece, 0.8-10Mpa the current cooled region that the close-connected cooling element of some is formed after the nozzle time, formed turbulent flow, the current extruding rolled piece of high pressure, formed the sufficient heat exchange of cooling water and rolled piece, the flow direction of having broken water has also been broken the gas-vapor mix body that is enclosed in around the rolled piece, and the aperture of the some of on cooling element, having arranged, can well discharge the steam that produces by the rolled piece chilling, this device is provided with outlet guide and outlet pipe in the place of outlet, most current are discharged this device by outlet pipe, through being arranged on the back-blowing device of its afterbody, redundant moisture is removed, when going out device, rolled piece obtained the proper temperature that rolling mill practice needs, reduced the content of its surface oxide layer, increased the rate of becoming a useful person, improved the surface quality of rolled piece, easy to use.
