Description

Technical Field

[0001] The present invention relates to the technical field of steel strip cooling, and in particular to a steel strip water cooling device and a water cooling method for a steel strip production line. Background Art

[0002] There are generally two types of steel belt water cooling devices: (1) A water tank and a water pump are provided beside the steel belt, and a nozzle is provided above the steel belt. The water inlet of the water pump is connected to the water tank through a water pipe, and the water outlet is connected to the nozzle through a water pipe. The water pump pumps water in the water tank to the nozzle, and the nozzle sprays water onto the steel belt. The water sprayed onto the steel belt absorbs the heat of the steel belt and then drips onto the ground and flows away from the sewer. This type of steel belt water cooling device cannot reuse water; (2) A water tank is provided below the steel belt, a water pump is provided next to the water tank, and a nozzle is provided above the steel belt. There is a nozzle. The water inlet of the water pump is connected to the water tank through a water pipe, and the water outlet is connected to the nozzle through a water pipe. The water pump pumps the water in the water tank to the nozzle, and the nozzle sprays water on the steel belt. The water sprayed on the steel belt absorbs the heat of the steel belt and flows back to the water tank. Although this steel belt water cooling device can reuse water, the water flowing back into the water tank will also bring heat to the water tank. After long-term use, the heat in the water tank accumulates more and more, resulting in an increase in water temperature, and the water cooling effect becomes worse and worse, making it difficult to reduce the temperature of the steel belt;

[0003] The invention patent with the announcement number CN115355663B specifically discloses a steel belt water cooling device. Since low-temperature water continuously enters the second water tank and medium-temperature water continuously flows out of the second water tank, the second water tank is not easy to accumulate heat and is not easy to heat up. Since medium-temperature water continuously enters the third water tank and high-temperature water continuously flows out of the third water tank, the third water tank is not easy to accumulate heat and is not easy to heat up. The water cooling effect is good and the temperature of the steel belt can still be reduced after long-term use.

[0004] Although the device can realize the recycling of cooling water and avoid the problem of rising water temperature during the recycling of cooling water, when the steel strip is cooled, the spraying of cooling water will wash away impurities attached to the surface of the steel strip, such as oil stains or metal filings. If such impurities accumulate in the cooling water for a long time without being cleaned up, the cooling water circulation pipeline will be blocked, affecting the use of the entire device.

[0049] A method for water cooling a steel strip for a steel strip production line comprises the following steps:

[0050] S1.

Then, the steel belt passes through the feed port 3 and passes through the water cooling box 1 to be cooled by the water mist cooling system. The motor 11 is conductive and runs, and the transmission shaft 22 rotates to drive the gear 23 to rotate. Then, under the action of the chain 24, the gear 1 20 is driven to rotate, and then the reciprocating screw 25 in the circulating sleeve 21 is driven to rotate. At this time, the piston plate 26 carries the reciprocating screw 25 to reciprocate outside, and then The piston plate 26 moves to the right, and the cooling water sucked by the circulating sleeve 21 is supplied to the water mist cooling system through the drain pipe 16 to cool the steel strip body 2.

[0051] S2, then the cooling water of the cooling plate 13 and the axial flow fan 17 cool down the steel plate for secondary cooling and the cooling water is recycled by the circulating water component. In this process, the axial flow fan 17 is conductive and rotates at high speed, blowing on the surface of the cooling plate 13, cooling the cooling plate 13 with air, and then heat conduction and cooling the cooling water with a certain temperature stored in the cooling plate 13;

[0052] S3. The heat sink 13 not only cools the water by heat conduction, but also temporarily stores and keeps the cooling water still, so that the impurities in the cooling water are precipitated to the bottom of the heat sink 13 for collection. When a certain amount of impurities are accumulated, the electromagnet can be controlled to conduct electricity, generating magnetic force to fix the pulley 1 7, the pulley 3 9 and the transmission shaft 22. The motor 11 then drives the pulley 2 8 to rotate, drives the pulley 1 7 and the pulley 3 9 to rotate, drives the connecting shaft 28 to rotate, and cooperates with the collecting barrel 14 and the spiral blade 29 to transport the accumulated impurities.
