Description

Technical Field

[0001] The invention relates to the technical field related to controlled cooling devices, and in particular provides a large bar rolling controlled cooling device. Background Art

[0002] In conventional rolled products, the mill temperature reaches 1050℃, and the heat of the high-temperature rolled products is lost in the subsequent cooling process. Water cooling after rolling is to use the residual heat to achieve the purpose of refining the steel structure and strengthening the mechanical properties of the steel, thereby achieving comprehensive improvement of the steel. The essence of this technology is to use the residual heat after rolling to implement re-line quenching and tempering treatment on the rolled products. Its mechanism is to use the residual heat after rolling of the steel to quickly cool the steel bars after rolling through water, which is the surface quenching structure of the steel bar, that is, the hardened structure of martensite, bainite, etc.; in the subsequent controlled cooling, the heat energy of its core is released, and the quenching structure uses its own residual heat for self-tempering, so that the martensite and bainite are finally transformed into fine and uniform tempered troostite or fine pearlite + ferrite. At the same time, the core and surface temperatures tend to be consistent, and the austenite structure in the center forms pearlite + ferrite to improve the mechanical properties of the product. The rolled product treated by water cooling effectively shortens the phase transformation incubation period, so its structure is significantly refined at room temperature. With the help of reasonable final rolling temperature, fine-grained steel products that meet the fine-grained steel requirements of GB1499.2-2007 can be produced.

[0003] The existing cooling control device will generate a large amount of mist during the spraying process, which will affect the judgment of the cooling temperature of the rod, making it impossible to control and judge the cooling degree of the rod.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] By arranging a plurality of rotatable conveying rollers inside the water storage tank, when large rods pass by, the conveying rollers can be prompted to rotate automatically, and then the rotating box can be rotated, prompting cooling water to be poured into the water inlet holes of the three rectangular cavities of the rotating box. Then, under the guidance of the transition plate, the water flows to the surface of the conveying rollers, thereby reducing the temperature of the conveying rollers themselves during the conveying process, and also having a partial cooling effect when conveying large rods, which can not only transport the rods, but also increase their own service life.

[0015] Driven by the reciprocating mechanism, the corresponding slide can drive the outer box, temperature monitor and other components to monitor the temperature of the rod when it is cooling at the edge of the rod. Then, in order to facilitate the temperature monitor to monitor the rod after spraying more accurately, mist will be generated when the sprayed water contacts the surface of the rolled rod. At this time, the second motor can drive the second shaft to rotate. The rotation of the second shaft can drive the mist dispersing fan on the outside through the belt, the first transmission wheel and the second transmission wheel to rotate. The mist dispersing fan can quickly swirl the mist to make it circulate faster. At the same time, the second bevel gear on the outside of the second shaft is meshed with the third bevel gear on the outside of the first shaft, causing the first shaft to rotate. The rotation of the first shaft drives the rotation of the first bevel gear, prompting the meshing worm below to rotate on the inside of the slider. The rotating blades at the end of the worm disperse the mist at the temperature monitor, so that the cooling effect can be determined according to the temperature.

[0016] The drive of the slide allows the L-shaped frames on both sides of one end to drive the hard pipe to move back and forth. When the large rod is transported, it moves synchronously with the large rod, allowing the straight nozzle and spiral nozzle at the spray pipe to perform water cooling operations on the surface of the large rod.

When the rod passes through the conveying roller 18, the conveying roller 18 is driven to rotate by itself, and then the rotating boxes 40 at both ends are driven to rotate during the rotation process, so that the cooling water below the water storage tank 20 is poured into the rotating box 40 from the water inlet holes 45 of the three rectangular cavities of the rotating box 40, and then turned to one side. When the rod is in the direction of rotation, the water flows to the surface of the conveying roller 18 under the guidance of the transition plate 44, so that the temperature of the conveying roller 18 itself can be reduced during the conveying process, and a partial cooling effect can also be achieved when conveying the rod. Then, driven by the reciprocating mechanism, the corresponding slide 14 moves on the frame 2 with the rotation of the screw 17, and the slide 14 drives the outer box 36, the temperature monitor 35 and other components to monitor the temperature of the rod when it is cooled at the edge of the rod.

When the sprayed water contacts the surface of the rolled rod, mist will be generated. In order to facilitate the temperature monitor 35 to perform more accurate monitoring of the rod after spraying, the second motor 15 can drive the second rotating shaft 41 to rotate. The rotation of the second rotating shaft 41 can drive the mist dispersing fan 29 connected to the outside through the belt 31, the first transmission wheel 28, and the second transmission wheel 30 to rotate. The mist dispersing fan 29 can quickly swirl the mist, making it circulate faster. At the same time, the second bevel gear 39 on the outside of the second rotating shaft 41 is meshed with the third bevel gear 42 on the outside of the first rotating shaft 38, causing the first rotating shaft 38 to rotate. The rotation of the first rotating shaft 38 drives the rotation of the first bevel gear 27, prompting the worm 33 meshing under the first bevel gear 27 to rotate on the inside of the slider 32, and the rotating blades 34 at the end of the worm 33 blow away the mist around the temperature monitor 35, so that the cooling effect can be determined according to the temperature.
