Abstract
The utility model discloses a novel high-efficiency intensive-pressure water cooling device for bars, which comprises guide pipes, a nozzle support and a middle pipe. One of the guide pipes is mounted on one side of the nozzle support, one end of the middle pipe is mounted on the other side of the nozzle support, a group of water cooling nozzles is clamped between the guide pipe and the nozzle support, the other guide pipe is mounted at the other end of the middle pipe, a plurality of turbulent tubes are mounted in the middle pipe, and an inner cavity of each turbulent tube is a kidney-drum-shaped passage with two big ends and smaller middle. The novel high-efficiency intensive-pressure water cooling device for bars adopts the turbulent tube technology, utilizes the optimum arrangement of converging and diverging through the optimum geometrical angles, and can form cyclone water flows, thereby guaranteeing the maximum value of heat exchange rate between cooing water and a bar penetrating through the cooling water, solving problems of poor cooling effect of existing nozzles, severe abrasion of the nozzles, water resource waste due to failure of using turbid circulating water and the like, and being capable of greatly reducing processing accidents of jamming after being used.
Description
Technical field
The utility model relates to a kind of Cooling Control Technology of metallurgy industry rolled products, relates in particular to the water-cooling apparatus of wearing behind the rolling bar.
Background technology
As everyone knows, the controlled rolling technology of low-alloy steel is by refinement deformed austenite crystal grain, to ferrite and pearlitic phase transformation, form the ferrite crystal grain of refinement and comparatively tiny pearlite pelletizing through austenite, thereby reach the obdurability of raising steel and the purpose of welding performance.The control process for cooling is the cooling velocity difference of utilizing after the control rolled piece rolls, control the tissue and the performance of steel, can under the prerequisite that does not reduce rolled piece toughness, further improve the intensity of steel by the control cooling, and shorten hot-strip cool time, along with the difference of steel grade, the obdurability of control cooling steel depends on rolling condition and cooling condition.Wearing key technology in the water cooling process at bar is nozzle setting on the cooling device water inlet body, and it directly has influence on the quality of bar.Traditional nozzle comprise deflection cone and on tapered sleeve, and form the annulus between deflection cone and the tapered sleeve, and on the conical surface of deflection cone, be provided with many guiding gutters, after cooling water enters, spray at a high speed through this guiding gutter and annulus, to impact the bar that from the water conservancy diversion taper hole, passes through, make it in cooling, to move forward.Yet because the setting of nozzle guiding gutter often causes many cooling waters to squeeze mutually when impacting the bar surface, the nozzle kinetic energy rejection is bigger, the cooling effect deficiency, and temperature uprises, and finally influences the quality of bar.Guiding gutter very easily forms pitting in addition, makes pod apertures excessive and reduce to spray kinetic energy, and tapered sleeve also needs frequent replacing, increases the spare part cost.Moreover for guaranteeing water flow jet speed, the annulus must keep less spacing, therefore the easy plug nozzle of impurity in the water can not utilize erosion ring water to cool off, and can only use clean circulating water to cool off like this, cause the waste of water resource, be unfavorable for reducing cost.。
The utility model content
The utility model purpose is to overcome the deficiencies in the prior art, provide a kind of simple in structure, good cooling results, new and effective bar cooling wear-resisting, that can not stop up to wear the water device, the cooling effect that the existing nozzle of solution causes is poor, nozzle wear is serious, and can not use erosion ring water to cause problems such as water resource waste.
The technical solution of the utility model is achieved in that
A kind of new and effective bar is worn water-cooling apparatus, comprise guide pipe, water-cooled nozzle, nozzle bearing, intervalve and turbulent pipe, a described guide pipe is installed in a side of described nozzle bearing, one end of described intervalve is installed in the opposite side of described nozzle bearing, between described guide pipe and nozzle bearing, clamped one group of water-cooled nozzle, another guide pipe is installed on the other end of described intervalve, it is characterized in that: several turbulent pipe are installed in described intervalve, and described turbulent pipe inner chamber is the little waist drum type passage in big centre, two.
The utility model compared with prior art has following advantage:
1. this new and effective water-cooling apparatus of wearing adopts the turbulent pipe technology, has used optimized geometric angle to amass wealth by heavy taxation! Dispersing the best of shape arranges, can form the current of vortex, thereby guarantee that the rate of heat exchange of bar between cooling water that is passed reaches maximum, the cooling effect that the existing nozzle of solution causes is poor, nozzle wear is serious, and can not use erosion ring water to cause problems such as water resource waste, use the stifled steel technology accident in back to reduce greatly.
2. the turbulent pipe inner chamber is the little waist drum type passage in big centre, two, has guaranteed the continuity of vortex water flow at cooling section.
3. can follow according to different rolling mill practices and regulate corresponding hydraulic pressure, simple to operate, it is convenient to observe.
