Description

Technical Field

[0001] The invention relates to a high-pressure water descaling cover for sealing high-pressure water and iron oxide scale splashed during the descaling process of a slab, belonging to the technical field of steel rolling equipment. Background Art

[0002] High-pressure water descaling machine is a key equipment of plate rolling production line. When the slab with qualified heating temperature is transported to the descaling machine through roller, the high-pressure descaling water injection valve is opened, and high-pressure water of about 16MPa to 25MPa is ejected from the nozzles of the upper and lower descaling manifolds. The impact force and shovel force of high-pressure water are used to break the oxidized iron scale and separate it from the steel billet matrix. At the same time, the high-pressure water washes away the oxidized iron scale in the set direction.

[0003] The high-pressure water descaling machine is mainly composed of the descaling roller base, descaling roller, upper and lower descaling headers, upper header height adjustment device, and descaling cover. The descaling cover is mainly used to seal the high-pressure water and splashing iron oxide during the slab descaling process to prevent the high-pressure water and oxidized iron oxide from splashing and injuring people and polluting the environment. The descaling cover installed on site needs to cover the descaling roller and descaling header tightly.

[0004] The traditional descaling cover has a relatively large and complex structure. The descaling cover is usually installed on the descaling machine roller base by means of flat rubber sealing and bolt fastening. The descaling roller and descaling manifold installed inside the descaling cover are exposed to high-temperature billet baking and high-pressure descaling water and iron oxide splashing and washing for a long time, which inevitably leads to failure. Once a failure occurs, the descaling cover needs to be removed for replacement and maintenance. It takes more than 10 hours to remove and install the traditional descaling cover once, which often causes long-term production interruption accidents.

[0005] The descaling hoods of large descaling machines currently designed at home and abroad have complex structures and are all fixedly installed, which cannot meet the convenience of equipment maintenance and repair. In addition, the upper descaling header usually requires a height adjustment range of 200-500mm, and the sliding fit and sealing schemes between the upper descaling header and the descaling hood have serious defects. They fail due to rust and iron sheet accumulation, and the sealing is poor, causing the upper header height adjustment function to fail, which cannot meet the needs of on-site use.

[0006] Therefore, it is very necessary to completely optimize the descaling hood of the traditional high-pressure water descaling machine. Summary of the invention

The water retaining chain frame plates 10 and the water retaining chains 12 can prevent the overflow of high-pressure water and iron sheets in the horizontal direction.

[0022] Figure 1 , 2 It is shown that the lower edges of the two side plates 8 extend below the center of the roller, and the lower ends of the two side plates 8 have arc grooves 19 corresponding to the roller diameter position of each roller 1. The diameter of the arc groove 19 matches the roller diameter of the roller 1, and the arc grooves 12 are respectively mounted on the roller 1. The side plates 8 have the function of limiting the deviation of the blanks like the side guides of the traditional descaling roller, and the lower edges of the side plates 8 extend below the center of the descaling roller to seal the high-pressure water and iron oxide.

[0023] Figure 1 , 4It is shown that the cover support plate 13 is a rectangular plate, and the upper end of the plate surface of the cover support plate 13 has an arc groove 19 corresponding to the roller diameter position of each roller 1, and the radius R of the arc groove 19 is 1-2mm larger than the roller diameter r of the descaling roller.

[0024] Figure 1 , 4 It is shown that the lower end of the cover support plate 13 is vertically welded on the descaling roller base 5, and there are multiple vertical slots 17 on the cover support plate 13. The openings of the slots 17 are respectively opposite to the lower ends of the main frame plate 6 and the water retaining chain frame plate 10.

The two upper descaling manifolds 4 are respectively embedded in two groups of opposite upper descaling manifold chutes 15, and the upper descaling manifold 4 and the upper descaling manifold chutes 15 are in sliding fit. When the descaling cover is installed and hoisted, the upper descaling manifold 4 can enter or slide out from the lower end of the upper descaling manifold chutes 15, and the descaling cover is not constrained by the upper descaling manifold 4, and can be hoisted as a whole without obstruction.

The rectangular steel plate on the left side of the guide groove 14 is arranged at a 90° plumb bob, and the rectangular plate on the right side is arranged at a 20° tilt according to the high-pressure water incident angle. The high-pressure water sprayed by the lower descaling header 3 and reflected by the upper descaling header 4 can be completely collected. The high-pressure water is ejected vertically downward after diversion, thereby constraining the kinetic energy of the high-pressure water to be horizontally ejected toward the inlet and outlet of the descaling machine.

[0027] Figure 1 , 3It is shown that the lower parts of the two main frame plates 6 and the lower parts of the two water retaining chain frame plates 10 have horizontal rectangular openings 16, respectively. The rectangular openings 16 match the running channels of the roller 1 and the steel billet 2, and the plate surfaces of the two main frame plates 6 and the two water retaining chain frame plates 10 are opposite to the gap between the two roller shafts of the roller 1. A plurality of roller guide plates 20 are fixed to the upper edges of the rectangular openings 16 of the two main frame plates 6 and the two water retaining chain frame plates 10, respectively. The roller guide plates 20 are fan-shaped parts, and the plurality of roller guide plates 20 are sequentially spaced along the upper edges of the rectangular openings 16, with a spacing of 300-350mm in the width direction. The plate surfaces of the roller guide plates 20 are parallel to the side plates 8, and the upper ends of the roller guide plates 20 are 25-35mm lower than the upper ends of the roller shafts of the roller 1. The roller guide plates 20 are used to prevent the billet from buckling and tipping over, and guide the billet to run smoothly on the roller.

[0028] Figure 1 , 2 , 5 and 6 show that in order to prevent high-pressure water and iron sheets from splashing onto the outside of the descaling cover, the descaling cover is also provided with a sealing structure of a chute bottom sealing plate 21 and a chute side sealing plate 22.

The top screw 24 is adjusted to make the chute side sealing plate 22 close to the side plate 8 of the descaling cover, maintaining a gap of 1-2mm, and the gap is lubricated with dry oil. When the upper descaling manifold 4 is adjusted up and down in height, the chute side sealing plate 22 moves with the upper descaling manifold 4. The width of the chute side sealing plate 22 is greater than the width of the upper descaling manifold chute 15. The chute side sealing plate 22 covers the outer side of the upper descaling manifold chute 15 of the side plate 8, and the two sides are 60-80 mm wider than the upper descaling manifold chute 15, respectively, to ensure that the gap between the upper descaling manifold chute 15 and the upper descaling manifold 4 is completely covered.

[0031] Figure 1 , 2, 5 and 6 show that the sealing structure also has a U-shaped seal. The U-shaped seal 10 is welded by sandwiching a 80mm×80mm square steel between two 30mm thick steel plates, leaving a 80mm cavity in the middle.
