Description

Technical Field

[0001] This utility model relates to the technical field of blast furnace slag flushing system equipment, specifically to a blast furnace slag flushing trough lining plate casting device, which is suitable for protecting the inner wall of the slag trough and enhancing its wear resistance during the blast furnace slag flushing process, extending the service life of the slag trough, and reducing maintenance and replacement costs. Background Technology

[0002] Existing blast furnace slag flushing systems mainly use steel or alloy liners to resist high temperatures and erosion. However, these materials are susceptible to corrosion from chloride ions in slag water and steam, resulting in short liner lifespan, frequent maintenance, and high repair costs. To improve the durability of slag flushing equipment, a utility model patent (patent number: CN 221296941 U) proposes a blast furnace water flushing slag flushing device and casting mold. By casting wear-resistant high-alumina castable into the slag flushing body, the service life of the liner is extended, and the frequency of equipment maintenance and spare parts costs are reduced.

[0003] However, this device still has some shortcomings in practical applications. First, due to the lack of an effective venting structure, air bubbles generated inside during the pouring process are difficult to expel, leading to stress concentration inside the lining plate, which affects the pouring quality and the overall pass rate of the lining plate. In addition, the structural design of the device makes it inconvenient to move the device after pouring, increasing the difficulty of construction and installation.

[0004] To address the aforementioned shortcomings, this utility model improves upon existing patents by designing a blast furnace slag trough lining casting device with an observation and exhaust system that facilitates unloading, thereby improving casting quality and installation convenience, and meeting the requirements for long service life and low maintenance of blast furnace slag troughs. Utility Model Content

[0005] The present invention aims to overcome the defects of existing blast furnace slag flushing trench liner casting devices, such as low casting quality, low pass rate and inconvenient transportation, and to provide an improved blast furnace slag flushing trench liner casting device. A blast furnace slag trough lining plate casting device is characterized in that: the device is provided with an observation and venting system (1), which includes an anti-falling block (1-1), a venting hole (1-2), an anti-protrusion block (1-3), and an observation hole handle (1-4) for monitoring the concrete solidification and venting air bubbles during the casting process. The device also includes reinforcing bars (2), which are distributed in the horizontal and vertical directions at key parts of the slag trough body. The device includes an upper template (3) and two side templates (4) for controlling the shape of the concrete. The device also includes an outer bottom template (5) which is integral with the poured concrete and is not removed after pouring, providing permanent bottom support. The device is equipped with a lifting lug device (6) located above the template for hoisting and moving the casting mold.

[0006] Main features: 1. Observation and Venting System: This device is equipped with an observation and venting system, which can observe the solidification of concrete in real time during the pouring process. At the same time, it can effectively remove air bubbles during the pouring process through the venting holes, reduce stress concentration caused by residual air bubbles, and improve the overall quality and pass rate of the lining plate.

[0007] 2. Modular Design and Removable Formwork: This device adopts a modular structure and removable formwork, which facilitates the removal of the upper formwork after pouring, making equipment maintenance and replacement easier and improving construction efficiency. The removable design not only facilitates operation but also helps control the accuracy during the pouring process.

[0008] 3. Reinforcing Rib Structure: The device is equipped with horizontal and vertical reinforcing ribs, which enhances the stability of the entire mold during the casting process, prevents the mold from deforming under pressure, and thus ensures the molding effect and long-term durability of the liner.

[0009] 4. Lifting lug device: The lifting lug device is integrated into the structure of the device, which facilitates the hoisting and position adjustment of the overall structure, significantly improves the ease of installation, and reduces the difficulty and risk in the transportation process.

Detailed Implementation

[0011] 1. Structural Description: The device includes an observation and venting system (1) to monitor the concrete pouring process and remove air bubbles, ensuring the lining is dense. The observation and venting system comprises several structural details: Anti-falling block (1-1): This block is located around the observation and venting system to prevent components in the observation hole area from falling during pouring and operation, thereby improving operational safety.

[0012] Vent holes (1-2): These are located around the observation holes. They allow gas to escape during the pouring process, reducing residual air bubbles and effectively preventing stress concentration.

[0013] Anti-bulge blocks (1-3): Installed around the vent holes to prevent bulging caused by concrete stress and ensure that the surface of the lining plate is flat after casting.

[0014] Observation hole handle (1-4): Set in the observation hole area to facilitate the opening, closing and adjustment of the observation hole by the operator during the pouring process, so as to better control the pouring situation and the venting effect. The observation and venting system (1) is used to monitor the concrete solidification during the pouring process and vent air bubbles, thereby improving the density of the lining and the quality of the finished product.

[0015] To improve the structural strength of the device, two reinforcing bars were designed in both the horizontal and vertical directions (2), distributed at different locations on the device. The reinforcing bars can provide effective support during the pouring process, preventing deformation caused by the weight and pressure of the concrete, thereby ensuring the forming effect of the lining plate.

[0016] The top of the device is covered with an upper template (3) to control the shape consistency of the concrete. The upper template is slightly longer than the outer bottom template (5) to facilitate the smooth removal of the upper template after pouring, while ensuring that the formed lining plate is a flat concave structure, which is U-shaped when viewed from the side.

[0017] The two side formworks (4) form the side walls of the mold, maintaining the lateral stability of the concrete during the pouring process and preventing lateral overflow. The two side formworks can be removed after the pouring is completed, which facilitates subsequent inspection and replacement.

[0018] The outer bottom formwork (5) is located at the bottom of the mold. After the concrete is poured, it becomes an integral part of the concrete and is used as a permanent support structure to ensure the long-term stability of the lining plate. The outer bottom formwork plays a supporting role throughout the pouring process and is not removed to maintain the integrity of the concrete structure.

[0019] To facilitate the hoisting and movement of the device, a lifting lug device (6) was designed into the structure. The lifting lug is located above the template, and hoisting equipment can be used to position and install the overall structure through the lifting lug. This design greatly simplifies the transportation process, reduces the difficulty of manual operation, and improves safety.

[0020] 2. Usage process: During implementation, the device is first positioned and adjusted to a suitable location using the lifting lugs (6). Concrete pouring is then carried out, with the pouring process monitored and air bubbles removed via the observation and venting system (1). During pouring, reinforcing bars (2) provide necessary support to prevent structural deformation. After pouring, the upper formwork (3) and side formwork (4) are removed, leaving the outer bottom formwork (5), which is integrated with the concrete, as a permanent support.

[0021] 3. Implementation advantages: This utility model of a blast furnace slag flushing trench liner casting device significantly improves casting quality and finished product qualification rate through optimized structural design. The observation and venting system (1) effectively removes air bubbles, reduces stress concentration, and thus improves the density and strength of the liner. At the same time, the modular design and the application of the lifting lug device (6) simplify the installation and transportation process. After casting, the upper template (3) and the side templates (4) can be easily removed, while the outer bottom template (5) is retained as a permanent support structure. The horizontal and vertical arrangement of the reinforcing ribs (2) improves the structural stability of the device during the casting process, extends the service life of the liner, and reduces maintenance needs. In addition, the wear-resistant concrete material replaces the traditional steel liner, effectively reducing maintenance and replacement costs, and can meet the high-temperature and high-corrosion environment requirements of the blast furnace slag flushing trench, providing an efficient, economical, and durable solution for the stable operation of the blast furnace.
