Description

Technical Field

[0001] The invention relates to a device for rapidly cooling finished products used for bar steel rolling, and belongs to the technical field of bar steel rolling equipment. Background Art

[0002] Bar rolling is a metal plasticity processing process that involves applying pressure to a steel billet through rollers, causing it to plastically deform, resulting in a steel bar of the desired cross-sectional shape and size. This process is primarily used to produce a variety of round, square, hexagonal, and flat steel bars. After bar rolling, the finished product requires rapid cooling to improve production efficiency, necessitating the use of cooling equipment.

[0003] Chinese patent (CN118477904A) discloses a hot-rolled steel plate cooling device comprising two spray systems mounted at the upper and lower ends of a conveyor roller frame and a vibration motor mounted on the conveyor roller frame. Each spray system comprises a rapid cooling section, a transition cooling section, and a uniform cooling section, all connected in sequence to a spray main pipe. The rapid cooling section is equipped with spray tips at a fixed angle a; the uniform cooling section is equipped with spray tips at a fixed angle b; the angle c of the multiple spray tips in the transition cooling section linearly changes from angle a to angle b along the discharge direction. The vibration motor is mounted on the conveyor roller frame within the transition cooling section. By dividing the spray system into rapid cooling, transition cooling, and uniform cooling sections, this device can adaptively cool the steel plate in stages according to the temperature changes after hot rolling, providing precise control over the cooling process, optimizing the internal structure and performance of the steel plate, and improving product quality and production efficiency. Although current cooling equipment can also achieve cooling treatment for rolled steel materials, cooling by spraying will generate a large amount of hot steam. Since the coolant evaporates quickly due to heat, it will also react with the metal to produce some harmful gases. At the same time, after spray cooling, it is difficult to clean the equipment, and the heat is not effectively recycled, so the actual application effect of the equipment is not good.

[0028] Working principle: When the rods are cooled, the rods to be cooled are put into the cooling box 6 through the pipe inlet 7, and the rods will accumulate on the inclined surface of the heat recovery box 43. During this process, the water in the heat recovery box 43 can absorb the heat of the rods. At this time, the water temperature can be steadily increased to complete the heat recovery. When the water body is heated to a certain temperature, it can be automatically discharged through the water outlet pipe 44 for utilization. At this time, a new round of water can be re-added into the heat recovery box 43 through the water inlet pipe 41, continuously cooling the rods and realizing heat recovery at the same time. At the same time, the drive motor 8 can be turned on to drive the reciprocating screw 12 to rotate, and the reciprocating screw 12 can control the reciprocating movement of the walking accessories 9 thereon. During this process, the side wheels 9211 can roll on the inner upper wall of the cooling box 6, driving the bottom shaft 9213 and the multiple fan blades 9212 outside it to rotate. The multiple fan blades 9212 can generate high-speed airflow in the wind cover 922, and finally discharged through the air outlet plate 924 to blow to the rods, thereby realizing synchronous air cooling of the rods. When the walking accessory 9 moves, it can synchronously drive the walking wheel 95 to roll on the bottom inner wall of the heat recovery box 43. At this time, the liquid turning plate 94 can rotate synchronously to achieve stirring of the water body, improve the fluidity of the water body, and improve the heat recovery effect of the water body. When the walking accessory 9 moves, it can also synchronously drive the installation frame 9216 and the multiple built-in rollers 9217 to move synchronously. The multiple built-in rollers 9217 can be attached to the surface of the placed rods under the action of the set spring shaft 9214. As the walking accessory 9 moves, they synchronously move on the surface of the rods, which can ensure the regularity of the placed rods, thereby ensuring the rational use of the placement space and avoiding space waste. After the bars have cooled and need to be discharged, the connecting rod 112 is directly rotated through the adjusting sleeve 111. The connecting rod 112 can drive the baffles 113 on both sides to deflect synchronously. At this time, the baffles 113 on both sides lose their shielding against the baffle door 3. Since the heat recovery box 43 is in a stepped shape, the bars arranged on the inclined surfaces on both sides of the heat recovery box 43 can slide down quickly. At this time, the baffle door 3 is opened, and the discharged bars can be automatically collected in the collection tray 2.

[0029] The present invention combines liquid cooling with air cooling by being equipped with walking accessories and heat recovery components, thereby achieving rapid cooling of the rods, and the air cooling structure can be displaced in real time to ensure the cooling effect and uniformity of each part of the rods, while being able to collect heat to avoid heat waste, and the cooling water can be automatically and continuously replaced to continuously ensure the cooling effect of the rods and improve the cooling efficiency of the rods; by being equipped with liquid turning plates and walking wheels on the walking accessories, the water body can be stirred, the fluidity of the water body can be improved, the heat recovery effect of the water body can be improved, the regularity of the placed rods can be ensured, thereby ensuring the rational use of the placement space and avoiding space waste; by being equipped with an adjusting component, the rods can be quickly and automatically exported through simple operations after cooling through the adjusting component, and there will be no residue, which greatly improves the convenience and speed of taking out the material after cooling the rods and improves the actual application effect of the equipment.

Any technician familiar with this technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solutions and inventive concepts of the present invention, should be covered by the scope of protection of the present invention.
