Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of steel rolling cleaning, in particular to a descaling device for steel rolling with a slag blocking function. Background Art
[0002] After the billets of high-speed wire and bar wire in a steel rolling mill come out of the heating furnace, they are conveyed to a high-pressure water descaling tank through a roller table to start removing the scale on the surface of the billets. When the descaling tank uses high-pressure water to remove the scale, the scale knocked off by the water splashes out of the roller table along with the residual pressure. Although the equipment is equipped with iron chains to block the flying iron oxide, there are still small flaky iron oxide pieces splashing out from the holes of the iron chains. The site needs to be cleaned every hour, and there are often accidents where the iron chains are broken by the impact of the billets and splashed into the roller table equipment on the site, causing the roller bearings to get stuck, resulting in frequent replacement and maintenance by personnel. In addition to frequent cleaning, the splashing also brings injury accidents to the cleaning staff. Content of the Utility Model
[0003] The purpose of the utility model is to provide a descaling device for steel rolling with a slag blocking function, so as to solve the problems that the iron chains are broken by the impact of the billets and splashed into the roller table equipment on the site, causing the roller bearings to get stuck, resulting in frequent replacement and maintenance by personnel, and also bringing injury accidents to the cleaning staff.
[0004] To achieve the above purpose, the basic scheme provided by the utility model is: it includes a box body, a descaling ring is arranged in the box body, several high-pressure water guns are arranged on the descaling ring, a water pipe is communicated with the bottom of the box body, upper bearing seats and lower bearing seats are respectively arranged on both sides of the box body, vertical shafts are respectively connected between each upper bearing seat and the lower bearing seat, both vertical shafts movably penetrate through the box body, side baffles are fixedly connected to both vertical shafts, and a reset assembly for resetting the side baffles is arranged on both upper bearing seats.
[0005] The working principle of the utility model is as follows: the box body is located on the roller table platform, the billets are conveyed into the box body through the roller table platform, the billets are washed by the high-pressure water guns, and then the billets are conveyed to the side baffles, pushing the side baffles open. The internal iron oxide fragments are blocked in the box body by the side baffles. When the billets leave the side baffles, the reset assembly drives the side baffles to close and reset, and the impurities and debris inside the box body cannot fly out.
[0006] The beneficial effect of the utility model is that the side baffles are used to block the iron oxide slag generated after washing, so that there is no large amount of iron oxide slag blown out around the descaling machine, improving the dust splash in the surrounding working environment, and solving the problems of serious environmental pollution caused by the flying of iron slag and the injury of the staff.
[0007] Solution 2 is the preferred basic solution. The reset assembly includes a steering wheel, which is clamped with the upper bearing seat. The steering wheel is provided with a groove, in which a steel wire rope is placed. The two ends of the steel wire rope are respectively connected to counterweight block 1 and counterweight block 2. When the steel billet is transferred, the counterweight block applies downward force to the steel wire rope, and the steel wire rope drives the steering wheel to rotate. When the two counterweight blocks are balanced, the side baffle is reset. Since the counterweight block has a certain weight, the side baffle will not have a gap or open due to shaking or swaying when it is not working.
[0008] Solution 3, which is the preferred solution of Solution 2, has a plurality of anti-dropout plates threadedly connected to the steering wheel. The anti-dropout plates stabilize the steering wheel and the wire rope to prevent the wire rope from falling off the steering wheel.
[0009] Solution 4 is the preferred basic solution. An upper baffle is hinged in the box and is located between the side baffle and the dephosphorization ring. The upper baffle is set on the basis of the side baffle. When the steel is discharged, the billet first passes through the upper baffle, lifts the upper baffle, and then passes through the side baffle, which can further prevent the iron slag impurities in the box from splashing out.
[0010] Option 5 is the preferred option of Option 2. A plurality of rollers are provided on the box body, and both ends of each wire rope are placed on the rollers. The rollers can reduce the friction of the box body corners on the wire rope and extend the service life of the wire rope.
[0011] Solution 6, which is a preferred solution of Solution 4, has two rollers at the free end of the upper baffle, and the two rollers are located on both sides of the free end of the upper baffle, and a roller is rotatably connected between the two rollers. When the billet passes through the upper baffle, the billet directly contacts the roller in rotation, thereby reducing the wear of the billet on the upper baffle. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiment
[0018] The embodiment is basically as shown in the attached Figure 1 to the attached Figure 3 as follows: A steel rolling phosphorus removal device with a slag blocking function, including a box body 1, a phosphorus removal ring 3 is arranged inside the box body 1, several high-pressure water guns 4 are arranged on the phosphorus removal ring 3, a downcomer 2 is connected to the bottom of the box body 1, upper bearing seats 5 and lower bearing seats 6 are arranged on both sides of the box body 1 respectively, a vertical shaft 7 is connected between each upper bearing seat 5 and the lower bearing seat 6, the two vertical shafts 7 both movably penetrate through the box body 1, side baffles 8 are fixedly connected to the two vertical shafts 7, and a reset assembly 9 for resetting the side baffle 8 is arranged on both upper bearing seats 5. The reset assembly 9 includes a steering wheel 901, the steering wheel 901 is clamped with the upper bearing seat 5, a groove 902 is arranged on the steering wheel 901, a steel wire rope 903 is placed in the groove 902, several anti-disengagement plates 10 are threadedly connected to the steering wheel 901, both ends of the steel wire rope 903 are respectively connected with a counterweight one 904 and a counterweight two 905, the weight of the counterweight one 904 is 20 kg, the weight of the counterweight two 905 is 50 kg, several rollers 12 are arranged on the box body 1, both ends of each steel wire rope 903 are placed on the rollers 12, an upper baffle 11 is hinged inside the box body 1, the upper baffle 11 is located between the side baffle 8 and the phosphorus removal ring 3, two roller shafts 13 are arranged at the free end of the upper baffle 11, the two roller shafts 13 are located on both sides of the free end of the upper baffle 11, and a drum 14 is rotatably connected between the two roller shafts 13.
[0019] The implementation manner of this embodiment is:
[0020] When descaling the steel billet, the steel billet moves on the roller table and first enters the box 1. When passing through the descaling ring 3, the high-pressure water gun 4 rinses the steel billet. Then the steel billet continues to move forward, pushing up the upper baffle 11. The roller 14 makes relative movement with the steel billet. Next, the steel billet moves to the side baffle 8, pushing the two side baffles 8 outwards and passing through between the two side baffles 8. The rotation of the side baffle 8 drives the vertical shaft 7 to rotate, and the vertical shaft 7 drives the steering wheel 901 to rotate. At the same time, the steel wire rope 903 drives the counterweight two 905 to rise and the counterweight one 904 to descend. With the continuous driving of the roller table, the steel billet first leaves the upper baffle 11, and the upper baffle 11 rotates downward and restores itself by its own gravity. Then it leaves the side baffle 8. The gravity of the counterweight two 905 pulls down the steel wire rope 903, and the steel wire rope 903 drives the steering wheel 901 to rotate back. The steering wheel 901 drives the vertical shaft 7 and the side baffle 8 to rotate back to the original position, and the counterweight one 904 rises. At this time, the upper baffle 11 and the side baffle 8 block impurities such as iron oxide slag generated by the rinsing of the high-pressure water gun 4 in the box 1, and finally discharge through the drain pipe 2 from the box 1.
