Abstract
The invention relates to a turbulent pipe for a high-speed passing water cooler, which comprises water-cooling nozzles, an adjusting shim group and an intermediate pipe, wherein the right end of a water-cooling nozzle A is sleeved in a water-cooling nozzle B, the right end of the water-cooling nozzle B is sleeved in the intermediate pipe, and the adjusting shim group is arranged at the contact part of the outer ring of the intermediate pipe and the end surface of the water-cooling nozzle B; and three groups of lining pipes are arranged in the inner cavity of the intermediate pipe and are positioned by corresponding cylindrical pins, the left end of the inner cavity of the intermediate pipe is connected with the water-cooling nozzle B through a screw nail, and a sleeve is arranged at the right top end of the inner cavity of the intermediate pipe and is locked by a locking nut. The invention solves the problem of insufficient cooling capacity of a high-speed wire forming passing water system, reduces the cooling water quantity and the water supply pressure of the system, has no need of lowering the initial rolling temperature, reduces the power consumption, greatly reduces the occurrence frequency of process accidents of bleed-out and steel-clogging, greatly improves the production capacity, and has stable product performance.
Description
Technical field: the present invention relates to a kind of steel rolling turbulent pipe for high-speed passing water cooler.
Background technology: it is the device that eighties of last century is applied the eighties that known high-speed rod is worn water cooling system, and its structure is by feed pipe, water-cooled shower nozzle, drying tube, attacks sprinkler head in retaliation and combine.There are a plurality of water-cooled shower nozzles, each water-cooled shower nozzle to connect between a feed pipe, the water-cooled shower nozzle in every group of cooler and arrange drying tube, each water-cooled shower nozzle all has the operation of corresponding remote control switch then, can accurately control workpiece front end do not wear water, head by the back open the water-cooled shower nozzle automatically, the water-cooled shower nozzle is opened quantity and is set by master station.This high-speed rod water cooler has significant disadvantages, is that single passing water cooler cooling effect is poor.Because when wearing after water pressure has been increased to certain value, continue to improve pressure of supply water, the rolled piece cooling effect can only a little increase, and water resource and waste of energy are bigger, washes away steel simultaneously, stifled steel technology accident frequently takes place.Water-cooled shower nozzle standard-sized sheet on production line, when output, hydraulic pressure are adjusted to limiting value and still can not be satisfied the cooling controlling and rolling controlling process requirement, manufacturing enterprise can only significantly reduce start rolling temperature and mill speed, has seriously restricted production development so wear water cooling system cooling capacity deficiency.And the turbulence type of bar production application is at present worn water cooling system, have the cooling effectiveness height, invest characteristics such as little, but rolling bar speed generally is no more than 20 meters, and workpiece measurement exists
More than, to wear water pressure and can reach 1.8MPa, the rolled piece poker is worn water.And high-speed wire rolling speed is more than 70 meter per seconds, and workpiece front end can not be worn water, wears water pressure and generally is no more than 1MPa.So can not use.
Summary of the invention: purpose of the present invention will provide a kind of turbulent pipe for high-speed passing water cooler exactly, and it can overcome the existing problem of present high-speed rod passing water cooler well.The object of the present invention is achieved like this, turbulent pipe for high-speed passing water cooler, formed by water-cooled nozzle, adjustment shim pack, intervalve, it is characterized in that: the right-hand member of water-cooled nozzle A is enclosed among the water-cooled nozzle B, the right-hand member of water-cooled nozzle B is enclosed within the intervalve, is provided with the adjustment shim pack in intervalve outer ring and water-cooled nozzle B end face contact position; Be provided with three groups of bushing pipes in described intervalve inner chamber, and by corresponding straight pin location, left end is connected with water-cooled nozzle B by screw, right top is provided with cover and by locking nut locking, the hexagonal pointless screw is fastening in also being provided with on the locking nut.The present invention has not only solved the problem that high rapid-result wire rod is worn water system cooling capacity deficiency, the cooling water inflow and the pressure of supply water of system have also been reduced, need not to reduce start rolling temperature, reduced power consumption, greatly reduce the generation of badly bleeding, stifled steel technology accident, improved production capacity greatly, properties of product are stable.
Description of drawings:
Fig. 1 is a structural representation of the present invention;
1. water-cooled nozzle A, 2. water-cooled nozzle B 3. adjusts shim pack, 4. intervalve, 5. bushing pipe, 6. straight pin, 7. locking nut, 8. cover.
The specific embodiment: the invention will be further described below in conjunction with accompanying drawing;
Turbulent pipe for high-speed passing water cooler, formed by water-cooled nozzle, adjustment shim pack, intervalve, it is characterized in that: the right-hand member of water-cooled nozzle A1 is enclosed among the water-cooled nozzle B2, the right-hand member of water-cooled nozzle B2 is enclosed within the intervalve 4, is provided with adjustment shim pack 3 in intervalve 4 outer rings and water-cooled nozzle B2 end face contact position; Be provided with three groups of bushing pipes 5 in described intervalve 4 inner chambers, and by corresponding straight pin 6 location, left end is connected with water-cooled nozzle B2 by screw, right top is provided with cover 8 and by locking nut 7 lockings, the hexagonal pointless screw is fastening in also being provided with on the locking nut 7.During concrete enforcement,, design the special-purpose turbulent pipe of each kind according to actual workpiece measurement requirement; Keep former water-cooled shower nozzle and the remote control of wearing water system, guarantee that still workpiece front end do not wear water; The drying tube position of original system is replaced by newly-designed turbulent pipe, and the design conduit forms a whole water-cooled shower nozzle and turbulent pipe; The designing and arranging hydrophone, keep the turbulent pipe internal pressure stable, improve rolled piece poker and upper and lower surface cooling uniformity, the water trap that gathers is eliminated the hidden danger that high-temperature steam produced, because high-temperature cooling water produces a large amount of steam in the pipe, as not discharging easy generation fault smoothly, moment, serious the reduction worn the water effect, caused the rolled piece inhomogeneous cooling.Each wears six passing water coolers of arranged in series in the water cooling case.When crossing steel, remote valve gate control cooling water enters in the cooler from the water-cooled shower nozzle, passes through 2-3 turbulent pipe more continuously, takes away to become water behind a large amount of heats in rolled piece surface and add steam, discharge from the water trap of cooler afterbody at last, a small amount of steam is brought in next group passing water cooler or the drying tube.Every group of cooler bin end arranged that two are attacked in retaliation device, one be attack water in retaliation, another is to attack gas in retaliation, the steam on rolled piece surface is purged clean.The present invention strengthens cooling effect greatly, and the temperature drop ability can reach 300 ℃, advances final rolling temperature and laying temperature and can regulate at 700 ℃-1000 ℃, can satisfy the demand of producing variety steel technology fully.Adopt higher start rolling temperature can satisfy cooling controlling and rolling controlling process, reduced rolling power consumption.Mill speed is not worn the water cooling capabilities limits, has improved output.Only needing the unlatching low-pressure pump just can satisfy technology will show, has reduced and has worn the water power consumption.Adopt low pressure to wear water, the technology accident of wearing the stifled steel of water-cooled descends greatly.The rolled piece cooling is even, and properties of product are stable, product percent of pass improves greatly.
