Description
Technical field
The present invention relates to a kind of method and apparatus that improves the high-speed rod-rolling mill control cooling air-cooled efficient of line and intensity, belong to steel rolling process for cooling, equipment technical field.
Background technology
High-speed rod-rolling mill has all disposed stelmor (stelmor) control cooling line at present, the stelmor cooling mode has become the main process for cooling of steel industry high speed wire production, this technique is comprised of water-cooled section, a second wind cooling section, the water tank of a water-cooled section after by finish rolling realizes that the second wind cooling section comprises: the longer conveying roller diatom that is comprised of heat-resisting steel rider, be located at the many Fans below this conveying roller diatom.Armature wire when reaching the laying temperature that sets, is weaved silk lopping and uniformly dispersing on the stelmor rollgang through Laying head after water-cooled section cooling, carry out second wind cooling, finishes phase transformation.In actual production, behind the wire spinning forwardly the phase transition process in the air-cooled segment limit of blower fan substantially finish, the steel interior tissue forms, metallographic structure at this moment will determine serviceability and the deep processing performance in steel later stage.But because the cooling capacity of anterior blower fan is not enough, the degree of supercooling when causing wire internal tissue inter-variable is inadequate, and metallographic structure can not change by technological requirement fully at short notice, so that the tissue odds of steel is even, especially the high-carbon steel sorbitic rate is not high; When steel entered the cooling of rear portion blower fan, because phase transformation is finished, air-cooled impact on steel structural transformation this moment was very little, and rear portion blower fan air-cooled belonged to invalid cooling.Therefore this structural design and layout have caused anterior fan delivery not enough, and the unnecessary or superfluous problem of rear portion fan delivery.Therefore the cooling capacity that improves anterior blower fan is to improve the key of steel combination property.
For this reason, Chinese patent 2004100506912 discloses a kind of " high-speed rod-rolling mill stelmo line gas-mist cooling device and method ", is above the conveying roller of air cooling section spray cooling device to be set, and cooperates the below blower fan to carry out two-way cooling again.The problem that the method exists is: aerosol can only be sprayed onto the upper surface of wire rod, and the lower surface cooling of can't being sprayed uniformly, so there is the even problem of inhomogeneous cooling, the while is also easily caused steel upper surface rust staining; In addition because spray area can produce a large amount of fog, and should the zone usually be provided with the camera of observing the working condition of weaving silk for operating room, having exerted an influence to the observation of the situation of weaving silk of fog.
Another Chinese patent 2008100323341 discloses again a kind of " high-speed rod-rolling mill stelmo line cooling means and cooling device ", above conveying roller, to establish blower fan, cooperate the bottom blower fan to carry out two-way cooling, the method Main Problems is: the air-out wind direction that only has stelmo line below blower fan just can be realized during with conveyor roller formation certain angle, and prior art mostly is greatly the production line that wind direction and conveying roller consist of vertical angle, like this so that this method can not use at the Stelmor cooling line of this type; Simultaneously the air quantity of the portable fan of top, blast are much smaller than air quantity, the blast of below blower fan, and the cooling effect of the portable fan of top is affected; When heap steel accident occurs on the pipeline, although the top blower fan can be removed, comparatively bother in the operation in addition, easily cause increase downtime; Increase simultaneously the floor space of equipment and transformed input.
At present, the Main Means that improves the air-cooled intensity of Stanermo wind-cooling linear is: improve rollgang speed, more ventilating fan, improve power output.Rollgang speed is faster, laying of wire rod circle is more sparse, radiating rate is faster, is conducive to accelerate cooling velocity, but the excessive velocities of rollgang is to a certain degree the time, can shorten on the contrary the air-cooled time of wire rod circle, reduce cooling effect, make simultaneously the wire rod circle enter fast the collection reel, and increase collection volume operation easier, cause collection volume heap steel probability to increase, strengthened workman's labour intensity; Changing blower motor, to improve the power output cost higher, will bring up to 150000m3/h such as air output 116000m3/h, except re-starting the pouring motor base, also want branched nearly 400,000 yuan/platform that goes out, and construction period is longer, power consumption.Therefore, must be improved prior art.
