As shown in Figure 1, wire rod passes earlier photoelectric thermoscope (2) after being come out by finishing mill (λ), gives (3) signals of little processing single board computer, determines the number that bubble formula quencher (12) (see figure 4) in the hot-water line (4) is opened; Wire rod enters the hot-water line (4) with 10 bubble formula quenchers, wear water cooling, the number that bubble formula quencher is opened directly depends on the finishing temperature of wire rod, behind the hot-water outlet pipe, adjust to 800 ℃ ± 10 ℃ to guarantee wire temperature, enter then level cone spiral shell formula coiling machine (5), after being rolled into coil, one circle circle degeneration is being held on the circle bar (6), individual layer is stringing equably on bar, (see figure 5), rely on driving-belt (9) to promote to hold circle bar (6) and move horizontally, coil (21) (see figure 6) is immersed in the tank (7) simultaneously. Time and don't generation brittle failure for extension coil (21) stops in boiling water add 0.5% soap or compound tendering resistant agent in boiling water. After coil (21) surface temperature is down to 500～550 ℃, leave the water simultaneously. Hold circle bar (6) level run and locate to (8), the coil on the push-off pin, it is bundled that coil is packed, and is transported to the wire rod storage vault by conveyer belt (10). Holding circle bar (6) is returned by driving-belt (9) and delivers under the coiling machine (5).
Key device of the present utility model has following three parts:
(1), hot-water line and bubble formula quencher
The hot-water line structure as shown in Figures 2 and 3, bend pipe wherein with holes (11) is connected and communicates with bubble formula quencher (12), together is placed in the hot-water line (4).On the tube wall because of bend pipe with holes (11) circular hole is arranged,, be full of hot water, in bubble formula quencher (12), behind the airflow of feeding certain pressure, then be an air filled cavity, wherein do not have hot water so it communicates with hot-water line (4).The structure of bubble formula quencher (12) as shown in Figure 4.
Bubble formula quencher (12) is a steel cylinder, makes hole container (14) for one, and the steel bubble (15) of hollow cylindrical is made in the other end, is communicated with by inlet (16), is full of hot water in hole container (14) and the bend pipe with holes (11).Steel bubble (15) is by air supply duct (18) air supplied stream, with inlet (16), outlet (17) and bottom circular aperture (19) discharge from wire rod (13) of wherein hot water.
After the wire rod finish to gauge, enter the bend pipe with holes (11) that is full of hot water, because of vaporization forms one deck steam film around wire rod; After entering steel bubble (15) by inlet (16), steam film is on every side just taken away by airflow (air pressure is 300 millimeter water column); When wire rod is passed when entering bend pipe with holes (11) by outlet (17), just contact with boiling water again, because of the rapid vaporization of water, and form one deck live steam film around making wire rod.Rely on the vaporization of boiling water, make Steel Wire Surface produce chilling, surface temperature descends rapidly.After steam film was completed into, cooling rate slowed down; When wire rod entered in the next steel bubble, cooling rate can be further slack-off.In this period that cooling rate slows down, steel wire core portion heat outwards conduction and period of causing the Steel Wire Surface temperature recovery just.When wire rod passes steel when bubble of next quencher,, cause that wire surface lowers the temperature rapidly because of the vaporization once more of boiling water can cause chilling again; Be again later on that surface temperature is gone up ...So repeatedly, when making the wire rod core temperature reduce to about 800 ℃ faster, the hot-water outlet pipe enters reeling machine and batches.
(2), dial circle device and hold the circle bar
As shown in Figure 5, after wire rod was rolled into coil by level awl spiral shell formula reeling machine (5), a circle circle degeneration was stirred by dialling circle device (20) continuously at the head that is holding circle bar (6), made coil go up stringing holding circle bar (6).
(3), bear device and handling device
This device is installed in top, tank (7) two ends, as shown in Figure 6.When coil (21) all string hang over hold circle bar (6) after, level promotes to hold circle bar (6), make it to drop on and bear on the device (22), bear device (22), to hold circle bar (6) is placed on the transmission belt (9), rely on the transmission belt (9) of operation continuously, make and hold circle bar (6) and drive coil (21) and move forward in tank, the speed of transmission belt (9) operation depends on the time that coil should stop in boiling water; After reaching the immersion time, hold circle bar (6) and just in time move to handling device (23) and locate, rely on handling device (23) will hold circle bar (6) and propose tank, be placed on the steady arm (24), promptly finish the immersion process of cooling of coil.Rely on the sunken bottom (25) in the tank (7) constantly to change coil (21) and the point of contact that holds circle bar (6).
As can be seen from the above, the utility model and existing wire rod water bath processing device (for example ED method) and stelmor subtraction unit have tangible difference and significant superiority.
Advantage that the utility model and the comparison of ED subtraction unit are had and main difference thereof are:
(1), wire rod before batching, the ED method is to adopt the water-cooled tube of carry potential overflow device, has five sections.Rely on high pressure water (greater than 8 normal atmosphere) to wearing the water pipe sealing two ends, adopt the cold water cooling.Because this water pipe structure complexity of wearing, hydraulic pressure requires high, and cost is expensive, and the bad control of process of cooling.Simultaneously, cooling time can not the corresponding change with the variation of wire rod finishing temperature, thus the coiling temperature of wire rod and batch after the temperature of wire rod when inlet flume all can not keep similar substantially, to cause the fluctuation of wire rod mechanical property bigger.The utility model adopts the hot-water line with 10 bubble formula quenchers, preceding 6 bubble formula quenchers are often opened, back 4 bubbles formula quencher is by little processing single trigger, finishing temperature according to wire rod, select to open and close the number of quencher, just adjust the cooling situation of wire rod by finishing temperature, thereby the coiling temperature that can guarantee wire rod is at 800 ± 10 ℃, so can reduce performance difference between the different wire rods.
(2), drop on earlier after wire rod of the present utility model batches and hold on the circle bar, Deng a drum batch finish after, just by holding the tangential movement of circle bar, immerse whole drum in the tank simultaneously, behind certain hour, effluent trough simultaneously again, thus unanimity cooling time of each coil can be guaranteed, so the wire rod performance is more even.The coil of ED method is to batch on one side, Yi Bian fall in tank, the cooling conditions of each coil (cooling rate and cooling time) can't guarantee identical, thereby causes that the fluctuation of wire rod mechanical property is bigger, and particularly the two ends performance difference of a drum is bigger.
(3), the wire rod of ED method is each coil stack up tightly in tank, whole dish cooling, radiating rate is slower and inhomogeneous.The utility model is a coil in that to hold on the circle bar completion earlier a string, lines up one deck equably, thereby the radiating rate of wire rod is improved, and helps increasing the ultimate strength after the water-bath; Simultaneously, cool off also more even, thereby the fluctuation of mechanical property is everywhere further dwindled.
(4), the wire rod of ED method is to be cooled to the nucleate boiling just effluent trough that finishes after (100～150 ℃) in tank.For fear of brittle failure, the speed of cooling of wire rod can not be big, thereby limited the raising of wire rod intensity.Wire rod of the present utility model is to propose tank for a long time before nucleate boiling occurs, and therefore allows wire rod is taked bigger speed of cooling, so help improving the intensity of wire rod.
(5), the cooling time of the wire rod of ED method in tank is changeless basically, and the time that wire rod of the present utility model stops in tank can be regulated arbitrarily as required, therefore be easy to the conversion kind aborning, by the needs change soaking time of each kind.
(6), 0.5% polyvinyl alcohol of ED method employing only plays stable steam film, reduces the steam film speed of cooling, and the compound tendering resistant agent that the utility model is recommended can prevent that wire rod from forming martensite and producing brittle failure, reduction steam film cooling rate that again can be less in the water-bath process.The not brittle failure so allow wire rod after water-bath, to have than the high intensity of ED normal material.
Compare with the steyr palm-rubbing technique that extensively adopts in the at present domestic and international wire production, the utlity model has following advantage:
(1), floor space is less.At least 80 meters of produce line total lengths of steyr palm-rubbing technique, so the utility model is particularly suitable for middle-size and small-size wire rolling plants.
(2), the breakdown point of wire rod is than the height of steyr palm-rubbing technique, the fluctuation range of intensity is also less.
(3), the wire rod performance of steyr palm-rubbing technique production is subjected to the influence of workshop temperature and humidity, and wire rod performance of the present utility model is insensitive to workshop temperature and humidity.
(4), the steyr palm-rubbing technique before batching, the water cooling of wearing of wire rod is to adopt high pressurized overflow cold water pipe, complex structure, water content consumption is big, hydraulic pressure needs greater than 8 normal atmosphere, and the cooling conditions of wire rod can not change with finishing temperature.What the utility model adopted is water at atmospheric pressure, and simple in structure, water loss significantly reduces, and the wire rod cooling conditions can be regulated automatically by the variation of finishing temperature.
(5), every production line of steyr palm-rubbing technique need adopt the air-supply of four gas blowers, so the workshop noise is bigger, and the utility model does not have noise basically.
(6), set up the required output investment ratio steyr palm-rubbing technique of production line of the present utility model low 3/4ths.Whenever build a steyr palm-rubbing technique production line, need about 200,000 yuan of capital cost.
The utility model is applicable to the postheat treatment of rolling of various carbon steel and low alloy steel wire rods.
Be most preferred embodiment of the present utility model below:
After wire rod went out finishing mill, diameter was 5.5 millimeters.Pass with 8 hot-water lines of the bubble formula quencher of breakdown, be chilled to 800 ℃, enter level awl helix tube type reeling machine and be rolled into the circle that looses, fall, be put in the boiling water groove that contains 0.5% compound tendering resistant agent, stopped effluent trough 32 seconds holding on the circle bar.The mechanical property of the wire rod after the utility model is handled and the contrast of other method are as shown in table 1.
