The present invention relates to a kind of coolings by the wire coiling cooling device 1 of the wire coiling 2 of winding conveying, has lid
Unit 30, so as to be easy to adjust such as cooling velocity of rapid cooling or Slow cooling wire coiling 2.
In the following, being carried out to the relevant basic production of wirerods of wire coiling cooling device 1 present invention as described above
Explanation.
In general, the production technology of wire rod is as follows: adding steel billet (billet) with 1000~1200 DEG C in heating furnace
Then heat cools down the round wire rod of heat by roughing, middle roughing, middle finish rolling and finish rolling in water-cooled platform 4, then by receiving
It rolls up production line material and coils 2, then put on modified line.
At this point, wire coiling 2 produces the small-bore wire rod and diameter that diameter is 5.5~15mm according to its milling step
For the heavy caliber wire rod of 15~42mm.
In addition, by winder, such as Laying head 5 (laying head), forming non-concentric for small-bore wire rod
It after shape coils (coil) form, is heat-treated while conveying using conveying equipments such as roller conveyors 6, then passes through collection volume
After 7 (reforming tub) of bucket carry out collection volume, puts into and check on line.
That is, the material rolled by roll mill 3, is cooled down, and pass through by carrying out cooling water-cooled platform 4 using cooling water
As winder Laying head 5 and wound.
The wire coiling 2 so wound is continuously fallen and is placed on the conveying roller 6a of roller conveyor 6 and defeated
It send, while the wire coiling 2 wound passes through roller conveyor 6, passes through what is blown by the blowing unit 10 that lower part is arranged in
Cooling medium, that is, cooling air A (wind) is cooled down.
Also, the wire coiling 2 wound falls in the collection roll barrel 7 connecting with conveyer and is integrated volume as final products.
In addition, the cooling procedure of above-mentioned small-bore wire coiling 2 is further looked at, in the Laying head 5 as winder
In continuously winding for coil form and extract wire coiling 2, fall on the conveying roller 6a of roller conveyor 6 and conveyed.
The wire coiling 2 conveying on the way, the blowing unit 10 of more conveyer lower parts is set along conveyer
To conveyer Lateral supply, the air so blown touches transported wire coiling 2, by the line of the condition of high temperature before collection volume
Material coils 2 and is cooled to low temperature, thus executes the heat treatment process of wire coiling 2.
At this point, the temperature for winding and dropping down onto the wire coiling 2 of conveying roller 6a is about 800~900 DEG C or so, through supercooling
The temperature of wire coiling 2 be about 300~500 DEG C or so.
In addition, the blowing unit 10 includes the pipeline 13 that lower part is provided with pressure fan 12, configured on the top of pipeline 13
Have to form the jet element of the nozzle unit of air opening 11 20 21.The wind speed of cooling air supplied from air opening is about
20~50m/s or so.
The basic structure of above-mentioned wire coiling cooling device 1 of the invention is referred to Fig. 1.
At this point, for wire coiling 2, as shown in figure 4, non-concentric circular wire coiling 2 (unit: ring) can be divided
Centered on (CN), middle part (MI), three parts edge part (ED).
In addition, the blowing unit 10 is also known as stelmor (Stelmor), although having the intensity or line according to air-supply power
The advantages of material coils the cooling conditions such as 2 conveying speed, can obtain a variety of cooling velocities, but air-supply is adjusted to wire rod disk
It can be problematic in the width direction of volume 2.
For example, as shown in Figure 5 a, extracting wire coiling 2 from Laying head 5 and being placed on the conveying roller 6a of roller conveyor 6
And when being conveyed, there are larger for the mounting density between the edge part (ED) (ED in Fig. 4) of wire coiling 2 and central part (CN)
Difference, therefore, as shown in Figure 5 b, it is identical air-supply environment under be cooled material the time point undergone phase transition on can occur
100 DEG C maximum or more the temperature difference.
It should be noted that Fig. 6 is to indicate in actual job scene, with infra-red thermal imaging thermometer measure wire rod disk
The photo for rolling up the Temperature Distribution of the width direction of 2 (rings), in addition to caused by the superposition density variation as wire coiling 2 (between ring)
Except inhomogeneous cooling is even, due to ring one-dimensionally loading and cooling on a conveyor, serious superposition portion can occur between ring.
That is, the superposition density variation of wire coiling 2 causes to generate cooling insufficient heat spot (hot- in wire coiling 2
Spot) part.The heat spot part that this wire coiling 2 is superimposed, it is difficult to be cooled down with air supply mode, even if increasing air-supply
The material deviation as caused by cooling deviation can also occur for amount.
Also, remoter with a distance from Laying head 5, the central part (CN) of wire coiling 2 and the temperature history of edge part (ED)
Difference increase.
Namely based on the generation bring wire coiling 2 of this mounting density variation and heat spot part (overlapping portion)
The temperature deviation of the cooling velocity difference of central part and marginal portion finally makes in the direction of the width microcosmic of wire coiling 2
Tissue is different, bad so as to cause product.
Also, according to wire coiling 2 produced, there is the necessity for further decreasing cooling velocity, but even if adjust
Air output is saved, reducing cooling velocity, there is also limitations.
Therefore, has cover unit 30, in the present invention can be easy to adjust the cooling velocity of wire coiling 2.
That is, the wire coiling cooling device 1 of one embodiment of the present of invention, may include: blowing unit 10, with roller
The corresponding mode of the transport path of the wire coiling 2 conveyed on conveyer 6 configures, and cools down to wire coiling 2；Nozzle unit
20, it is arranged in the blowing unit 10, forms air opening 11；And cover unit 30, setting in the nozzle unit 20, with
It is opened and closed the air opening 11.
In particular, the uniform cooling of 2 central part (CN) and edge part (ED) can be coiled with guide line material, to the detailed of this
Illustrate, is illustrated later herein with reference to Fig. 2.
The opening and closing for the air opening 11 that the cover unit 30 above-mentioned is formed by adjusting by nozzle unit 20, to adjust
The cooling velocity of the wire coiling 2.This is illustrated later herein with reference to Fig. 2 and Fig. 3.

On 21, the cooling velocity of the wire coiling 2 is adjusted.
Also, the fixed heating part 22 may include the width direction configuration along the transport path of the wire coiling 2
Multiple heaters, the heating temperature of the multiple heater can be made mutually different, to make the heating temperature of central part (CN)
Degree is lower than the heating temperature of middle part (MI).
As shown in Figure 5 a, for the mounting density ratio of wire coiling 2, the mounting density ratio of middle part (MI) is higher than central part
(CN) mounting density ratio, therefore the cooling velocity of middle part (MI) is relatively lower than central part (CN).Therefore, by making middle part
(MI) heating temperature is lower than the heating temperature of central part (CN), and the cooling velocity of wire coiling 2 can be made uniform on the whole.
It deforms when wire coiling 2 is cooling in order to prevent because of the difference of cooling velocity, and in order to by wire coiling 2
