Description

Technical Field

[0001] The present application relates to the technical field of steel bar production, and in particular to a bar anti-corrosion device. Background Art

[0002] Bars are made of steel ingots through hot rolling or forging. With the improvement of industrial construction level, the production of bars has also developed greatly. Such bars are widely used in various fields, such as construction, transportation, home furnishing and so on.

[0003] In the production process of bars, rolling is a pressure processing method that utilizes the gap between a pair of rotating rollers to compress the metal billet through the gap, thereby reducing the cross-section of the material and increasing its length. In modern bar rolling, circulating water is generally used as roller cooling water or water for water penetration. During the cooling roller or water penetration rolling process, the circulating water evaporates and concentrates continuously, causing the chloride ion content in the water to increase exponentially and remain on the surface of the finished bar in large quantities, causing or aggravating the corrosion and rust of the finished product, seriously affecting the quality of the finished product and causing a large amount of losses. Therefore, there is an urgent need for a bar anti-corrosion device to reduce the chloride ion content on the bar surface and improve the problem of the bar being easily corroded. Utility Model Content

[0007] By adopting the above technical scheme, the rods enter the red steel channel, and new water is circulated through the water inlet pipe. The chloride ion content of the new water is low. Under the action of the high-pressure water mist nozzle, the surface of the rods passing through the cleaning chamber is continuously cleaned to remove the chloride ions on the surface of the rods, thereby slowing down the corrosion and rusting of the finished rods and improving the quality of the finished products.

[0008] Optionally, a deaerator is provided on the water inlet pipe.

[0009] By adopting the above technical solution, the deaerator can remove oxygen from the newly produced water, slow down the corrosion process of the rods, and further improve the production quality of the rods. The deaerator of the present application uses the steam produced in the process as the heat source of the deaerator without increasing energy consumption.

[0010] Optionally, a cleaning and blowing chamber is provided at one end of the red steel channel away from the cleaning chamber, an air inlet pipe is provided on the top wall of the fuselage, and a plurality of high-pressure air nozzles are provided on the inner wall of the cleaning and blowing chamber, and the plurality of high-pressure air nozzles are all connected to the air inlet pipe.

[0011] By adopting the above technical solution, when the rod passes through the cleaning chamber, the compressed gas in the air inlet pipe is ejected through the high-pressure air nozzle, thereby being able to clean and blow away the water stains remaining on the surface of the rod, keeping the rod dry and improving product quality.

[0012] Optionally, the gas introduced into the air inlet pipe is nitrogen.

[0013] By adopting the above technical solution, nitrogen can be used as a protective gas to isolate water and oxygen in the air on the one hand, and on the other hand, it can be used to purge residual water stains on the surface of the rod, keep the surface of the rod dry, reduce the progress of rust on the rod, and improve product quality.

[0016] Optionally, the top wall and the bottom wall inside the red steel channel are both provided with convex surfaces, and the convex surfaces are located between the cleaning chamber and the washing chamber.

[0017] By adopting the above technical scheme, when the rod enters the red steel channel, the rod will abut between the two upper and lower convex surfaces, thereby isolating the rod from the upper and lower high-pressure water mist nozzles and high-pressure air nozzles, preventing the rod from coming into contact with the high-pressure water mist nozzle or the high-pressure air nozzle when moving in the red steel channel, thereby causing damage to the high-pressure water mist nozzle or the high-pressure air nozzle, thereby protecting the safety of the rod anti-corrosion device of the present application and extending its service life.

[0018] Optionally, valves are provided on both the water inlet pipe and the air inlet pipe.

[0020] Optionally, a support seat is provided on the bottom wall of the fuselage.

[0021] By adopting the above-mentioned technical solution, the setting of the support seat can improve the overall stability of the fuselage, so that when the rod passes through the red steel channel, the shaking caused to the fuselage can be reduced, thereby improving the safety of the rod anti-corrosion device of the present application.

[0022] In summary, the present application includes at least one of the following beneficial technical effects:

[0023] 1. After the new water produced in this application is pre-treated by the upper water supply unit, the chloride ion content is low. When the rods are rinsed, no additional water consumption is required to effectively reduce the residual chlorine content on the surface of the finished product, improve the corrosion resistance of the finished product, slow down rusting, and improve the quality;

[0024] 2. When the rod passes through the cleaning chamber, the compressed gas in the air inlet pipe is ejected through the high-pressure air nozzle, so that the water stains remaining on the surface of the rod can be cleaned and blown away, keeping the rod dry and further improving product quality.

[0031] Reference Figure 1A water inlet pipe 3 is provided on the top wall of the body 1 located at the cleaning chamber 21. The water inlet pipe 3 is used to circulate new water. The new water is a water resource that has undergone specific treatment. The treatment process includes filtering, disinfection, desalination, and removal of harmful substances to reduce the chloride ion content in the water. A deaerator 6 is provided on the water inlet pipe 3 to remove oxygen from the new water that has passed through the deaerator 6 to slow down the corrosion of the rod.

[0032] Reference Figure 1 and Figure 2 A plurality of high-pressure water mist nozzles 4 are provided on the top and bottom walls of the cleaning chamber 21, and the plurality of high-pressure water mist nozzles 4 are connected to the cleaning chamber 21. Thus, through the high-pressure water mist nozzles 4 distributed up and down, new production water can be sprayed to various places on the surface of the rod, thereby achieving the effect of comprehensively cleaning chloride ions, improving the cleaning effect, and ensuring the product quality of the finished rod; a water flow pipe 5 is provided at the bottom of the cleaning chamber 21 of the fuselage 1, and the water flow pipe 5 is connected to the cleaning chamber 21, so that the water after cleaning can flow out through the water flow pipe 5, and the outflowing new production water will enter the cold water pool as the supplementary water of the system, saving overall water.

[0033] Reference Figure 1 and Figure 3 An air inlet pipe 7 is provided on the top wall of the body 1 located in the cleaning chamber 22, and a plurality of high-pressure gas nozzles 8 are provided on the top wall and the bottom wall inside the cleaning chamber 22. The plurality of high-pressure gas nozzles 8 are connected to the air inlet pipe 7, and compressed gas flows in the air inlet pipe 7. In this embodiment, the compressed gas is nitrogen, which is used to isolate oxygen and water in the air on the one hand and slow down the corrosion of the rod surface on the other hand to purge the residual water stains on the rod surface, reduce the residual chlorine on the rod surface, and improve the finished product quality of the rod.

[0034] Reference Figure 1 , Figure 2 and Figure 3 The top and bottom walls inside the red steel channel 2 are both provided with convex surfaces 9 by welding, and the convex surface 9 is located between the cleaning chamber 21 and the blowing chamber 22.
