Abstract
Description
Technical Field
[0001] The utility model belongs to the technical field of kiln casting, and in particular relates to a tooling for reserving expansion joints for kiln casting. Background Art
[0002] Due to the large-scale development of modern blast furnaces, castables have become the preferred refractory material for furnace construction because of their excellent properties of mechanized construction and easy repair. However, castables are prone to expansion and cracking when used under high temperatures, and expansion joints must be left. During the actual use of traditional through-type expansion joints, slag is easy to penetrate into the castable, damaging the internal thermal insulation refractory materials, and then damaging the furnace shell, causing the furnace shell to overheat. When constructing castables, Z-shaped seams are usually used to reduce the occurrence of overheating. However, when encountering large-area casting, the existing construction method of block casting with Z-shaped seams takes twice as much construction time as the traditional whole-circle casting with through seams. Therefore, a convenient and quick Z-shaped seam design is needed to achieve the purpose of whole-circle casting, thereby shortening the construction period and reducing construction costs. Summary of the invention
[0003] In view of the shortcomings of the prior art, the purpose of the utility model is to design a tooling for kiln casting with reserved expansion joints to cope with the problem mentioned in the background technology that the construction time of block casting with reserved Z-shaped joints is too long, the efficiency is low, and the construction cost is high.
[0004] To achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a tooling for reserved expansion joints in kiln casting, comprising a base and a main body, wherein the base is a rectangular plate structure, and a plurality of mortises A are arranged at intervals along the center line on the upper surface of the base, and the bottom of the main body is arranged on the base in cooperation with the mortise A.
[0005] The main body is a Z-shaped structure as a whole, and the main body includes a vertical plate A, a horizontal plate and a vertical plate B connected together. A plurality of mortises B are arranged at intervals on the edge of one side of the vertical plate A, and a plurality of protruding tenons A are arranged at intervals on one side of the horizontal plate. The tenons A and mortises B cooperate to connect the vertical plate A to one side of the horizontal plate, and a plurality of mortises C are arranged at intervals on the edge of the other side of the horizontal plate. A plurality of protruding tenons B and tenons C are arranged at intervals on both sides of the vertical plate B. The tenons B cooperate with the mortises C to connect the vertical plate B to the other side of the horizontal plate, and the tenons C cooperate with the mortises A to connect the vertical plate B to the base. When the size of the vertical plate B and the horizontal plate is insufficient, an extension plate is added.
[0006] The extension plate is used to cooperate with the situation that the vertical plate B and the horizontal plate are insufficient in size. One side of the extension plate is provided with multiple protruding tenons D at intervals, and the other side of the extension plate is provided with multiple grooves at intervals. When the extension plate is used for the vertical plate B: the tenon D is connected to the mortise A provided on the base, and the groove is matched with the tenon C provided on the vertical plate B; when the extension plate is used for the horizontal plate: the tenon D is connected to the mortise B provided on the vertical plate A, and the groove is matched with the tenon A provided on the horizontal plate.
[0007] The base and the main body are made of wooden boards and polyethylene boards, which have no pollution to the casting material and are easy to process.
[0008] The beneficial effects of the utility model are: the split structure is adopted, the adjustment can be made according to the actual size, the installation is convenient, the use is convenient, and the negative effects such as block casting and prolonged construction time caused by leaving Z-shaped expansion joints during casting are reduced.
