Description

TECHNICAL FIELD

[0001] The application relates to the technical field of metal processing, in particular to a controlled rolling and controlled cooling equipment for round steel rolling processing. BACKGROUND

[0002] The controlled rolling and controlled cooling process of steel is mainly a technology for producing plates. The core of the technology is to improve the strength, toughness and welding performance of the steel by controlling the heating temperature, rolling process and cooling conditions during rolling. However, when the steel is subjected to hot rolling, oxides will appear on the surface of the steel. When the controlled cooling device uses water to cool the round steel, the water flow will carry away the oxides on the surface of the round steel. Therefore, the water after cooling will contain oxides. If the water containing oxides is directly recycled by a water pump, the oxides will damage the water pump. Moreover, after the water is filtered by the existing filter structure, the filtered oxides need to be cleaned frequently to avoid blocking the filter mechanism, thereby increasing the workload of the staff.

The cooperation of the connecting strip 28 and the small rod 30 can prevent the oxide from falling to the ground when the staff kicks the collection box 8, thereby avoiding the scattering of the oxide and the subsequent cleaning of the staff.

[0031] In use, the first step: by placing the device under the round steel in the round steel rolling line, the recovery box 4 is arranged below the round steel. When the control cooling device sprays water to cool the round steel, the sprayed water flow will wash the oxide on the surface of the round steel while cooling the round steel. The oxide and the water that has not been evaporated will fall onto the two filter plates 5 in the recovery box 4. After passing through the filter plates 5, the oxide will be intercepted, and the filtered water will fall onto the water guide plate 24. The water flow will flow along the water guide plate 24 and fall into the movable bucket 16. When the movable bucket 16 is filled with water, it will rotate clockwise to make the bucket mouth downward. In this way, the water in the movable bucket 16 will be poured into the bottom of the recovery box 4. When the water in the movable bucket 16 is discharged, the movable bucket 16 will rotate counterclockwise to return to its original position. This will hit the discharge hopper 11, causing the discharge hopper 11 and the two filter plates 5 to vibrate. This will make the oxide on the filter plates 5 move towards the discharge hopper 11, and the oxide entering the discharge hopper 11 will move towards the discharge hopper 11. In this way, the oxide in the water can be separated while recovering water resources, and the accumulation of oxide can be avoided to affect the filtering effect of the recovered water.

[0032] The second step: the inclined strip 25 can effectively guide the water on the water guide plate 24, so that the water in the water guide plate 24 will be guided by the two inclined strips 25 and flow into the water guide hopper 39. In this way, the water on the water guide plate 24 can be concentrated and injected into the movable bucket 16, thereby increasing the frequency of rotation of the movable bucket 16, and the discharge speed of the oxide can be improved.

[0033] The third step: the support strip 12 and the soft plate 15 can support the movable bucket 16. When the movable bucket 16 rotates counterclockwise to return to its original position, the pad 38 will hit the discharge hopper 11, and the pressure spring 36 will be charged at the same time. In this way, the movable bucket 16 will continue to hit slightly back and forth several times after the impact, thereby further increasing the vibration frequency of the discharge hopper 11, and the discharge of the oxide can be further promoted.

[0034] The fourth step: through the limiting rod 27 can effectively avoid the activity bucket 16 clockwise rotation down when the rotation angle is too large to cause the activity bucket 16 discharge water and can not return to the original position, at the same time through the hose 26 can be buffered to reduce the impact of the activity bucket 16 impact limiting rod 27, through the movable plate 14 can be rotated with the activity bucket 16 back and forth, so as to produce wind power to increase the air flow velocity in the recycling box 4, can be recycled for water cooling treatment, so as to facilitate the next use of recycled water cooling.

[0035] The fifth step: through the activity bucket 16 downward rotation movement of drainage, the discharged water will be impulsive rotating plate 18 activity, so as to make each rotating plate 18 rotation movement, so as to produce wind power, so as to make the air in the square tube 21 flow faster, so as to make the air in the square box 22 flow faster, so as to make each L-shaped pipe 23 air flow faster, so as to make the guide plate 24 cooling, so as to make the water falling into the guide plate 24 cooling, so as to accelerate the cooling efficiency of the recycled water.

[0036] The sixth step: through the vibration of the discharge hopper 11 to move the oxide backward, when the oxide leaves the discharge hopper 11 will fall into the collection box 8, through the cooperation of the connecting strip 28 and the small rod 30 can avoid the staff walking to kick the collection box 8 to cause the oxide to fall into the ground, so as to avoid the oxide scattering to cause the subsequent staff to clean.
