Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of metallurgical engineering, relates to waterproofing of a descaling box, and particularly relates to a waterproof structure of a descaling box. Background Art
[0002] When steel billets are oxidized at high temperatures, a dense layer of scale forms on their surface. If this scale is not removed before rolling, it can affect the surface quality of the finished product. Therefore, it is essential to remove the scale from the billet surface before rolling. Currently, descaling manifolds are typically installed above and below the billet, with several descaling nozzles positioned on top of the manifolds. These nozzles utilize the mechanical impact of high-pressure water jets to remove the scale from the billet's upper and lower surfaces.
[0003] To ensure effective descaling, vertical strip-shaped through-holes are provided on the side walls of the descaling box at both ends of the upper descaling manifold. This allows the upper descaling manifold to be raised and lowered along the strip-shaped through-holes by a lifting mechanism to descale billets of varying thicknesses. To meet varying market demands, product thicknesses vary. When the descaling box is descaling billets of similar thickness, the upper descaling manifold is not raised high, and the strip-shaped through-holes are relatively short. Typically, a water baffle is provided on the upper descaling manifold corresponding to the side wall of the descaling box to ensure that the water baffle seals the strip-shaped through-holes as the upper descaling manifold rises and falls with it. However, when descaling billets of significantly different thicknesses, the descaling manifold needs to be raised and lowered to a higher height, such as 1 meter or even greater. To ensure effective waterproofing, the water baffle must be of sufficient length. Consequently, when the upper descaling manifold is lowered, the bottom of the water baffle is susceptible to collision with the roller table or infrastructure beneath it, thus easily damaging the descaling box. Summary of the Invention
[0004] In view of the above-mentioned deficiencies in the prior art, the purpose of the present invention is to provide a waterproof structure for a descaling box, which can effectively prevent high-pressure water from splashing out of the descaling box, thereby achieving a waterproof effect, and can also effectively avoid damage to the descaling box.
[0005] The technical solution of the present utility model is achieved as follows:
[0006] The first waterproof structure of the descaling box includes a descaling box body with an open top and a cover body arranged on the top of the descaling box body to close the top of the descaling box body. An upper descaling manifold and a lower descaling manifold are arranged in the descaling box body. A plurality of nozzles are provided on the upper descaling manifold and the lower descaling manifold. All nozzles are inclined toward the direction of the steel billet. Strip through holes are vertically opened on the side walls of the descaling box body corresponding to the two ends of the upper descaling manifold to facilitate the lifting and lowering of the upper descaling manifold along the strip through holes.
[0007] A first waterproof plate is provided below the upper descaling manifold, and a second waterproof plate is provided above the descaling manifold. Both the first waterproof plate and the second waterproof plate are telescopic waterproof plates. The upper part of the first waterproof plate is fixed to the upper descaling manifold, and the lower part of the first waterproof plate is fixed to the side wall of the descaling box corresponding to the lower part of the strip through hole. The lower part of the second waterproof plate is fixed to the upper descaling manifold, and the upper part of the second waterproof plate is fixed to the side wall of the descaling box corresponding to the upper part of the strip through hole.
[0008] The second type of descaling box waterproof structure includes a descaling box body with an open top and a cover body arranged on the top of the descaling box body to close the top of the descaling box body. An upper descaling manifold and a lower descaling manifold are arranged in the descaling box body. A plurality of nozzles are provided on the upper descaling manifold and the lower descaling manifold. All nozzles are inclined toward the direction of the steel billet. Strip through holes are vertically opened on the side walls of the descaling box body corresponding to the two ends of the upper descaling manifold to facilitate the lifting and lowering of the upper descaling manifold along the strip through holes.
[0009] A first waterproof plate is provided below the upper descaling manifold, and a second waterproof plate is provided above the descaling manifold. The first waterproof plate is a telescopic waterproof plate. The top of the first waterproof plate is fixed to the upper descaling manifold, and the bottom of the first waterproof plate is fixed to the side wall of the descaling box corresponding to the bottom of the strip through hole, so that the first waterproof plate can be telescoped during the lifting and lowering process of the upper descaling manifold to achieve waterproofing below the upper descaling manifold; the second waterproof plate is a hard sealing plate. The bottom of the second waterproof plate is fixed to the upper descaling manifold, and the cover body corresponding to the top of the second waterproof plate is provided with through holes corresponding to the second waterproof plates one by one, so that the upper descaling manifold can be lifted and lowered in the through holes during the lifting and lowering process to achieve waterproofing above the upper descaling manifold.
[0010] Furthermore, in the above two descaling box waterproof structures, the side wall of the descaling box body is a double-layer structure, and the first waterproof board and the second waterproof board are located in the gap of the double-layer structure of the side wall of the descaling box body.
[0011] Compared with the prior art, the present invention has the following beneficial effects:
[0012] 1. The utility model provides a first waterproof plate below the upper descaling header. The first waterproof plate is a telescopic waterproof plate. The upper portion of the telescopic waterproof plate is fixed to the upper descaling header, and the lower portion is fixed to the side wall of the descaling box corresponding to the lower portion of the strip through-hole. Since the telescopic waterproof plate is telescopic, the telescopic waterproof plate achieves waterproofing by telescoping during the telescoping process of the upper descaling header, thereby ensuring a waterproof effect. At the same time, no matter how high the upper descaling header is raised or lowered, it will not interfere with the roller frame provided below the upper descaling header and the infrastructure below the roller frame, thereby avoiding damage to the descaling box.
[0013] 2. The utility model provides a second waterproof plate above the upper descaling header. The second waterproof plate is a telescopic waterproof plate or a hard sealing plate. When the second waterproof plate is a telescopic waterproof plate, the telescopic waterproof plate is telescopic. During the telescopic process of the upper descaling header, the telescopic waterproof plate achieves waterproofing by telescoping. At the same time, no matter how high the upper descaling header is raised or lowered, it will not interfere with the cover provided above the upper descaling header, thereby avoiding damage to the descaling box cover.
[0014] When the second waterproof board is a hard sealing board, the service life of the second waterproof board can be effectively improved. At the same time, by setting a through hole for the lifting and lowering of the second waterproof board on the cover body, it is ensured that the cover body will not be damaged during the lifting process of the upper descaling manifold.

[0021] A first waterproof plate 4 is provided below the upper descaling manifold 1, and a second waterproof plate 2 is provided above the descaling manifold 1. The first waterproof plate 4 is a telescopic waterproof plate. The top of the first waterproof plate 4 is fixed to the upper descaling manifold 1 with screws 3. The bottom of the first waterproof plate 4 is fixed to the side wall of the descaling box 5 corresponding to the bottom of the strip through hole, so that the first waterproof plate 4 can be telescoped during the lifting and lowering process of the upper descaling manifold 1 to achieve waterproofing below the upper descaling manifold 1; the second waterproof plate 2 is a hard sealing plate.
