Technical Field

[0001] This utility model mainly relates to the technical field of slag retaining walls, specifically a slag retaining wall that is safe, protective, and easy to install. Background Technology

[0002] The slag retaining wall in the tundish is an important piece of equipment used in the steelmaking process to improve the cleanliness of molten steel. It is a partition wall installed inside the continuous casting tundish, and its main function is to block inclusions and slag in the molten steel, making the steel flow more smoothly, thereby increasing the floating time and separation rate of inclusions and improving the cleanliness of the molten steel. The slag retaining wall can be a single wall, double wall, or multi-wall structure, flexibly configured according to actual needs. Its material is generally high-alumina, but it can also be made of bricks inside the tundish, or made into precast blocks and placed inside the tundish. In recent years, to improve the service life and performance of the slag retaining wall, new materials such as low-cement corundum castables have also emerged.

[0003] According to the application number, a tundish retaining wall is disclosed, comprising a retaining wall body, which is composed of a main wall and side walls. Two sets of side walls are provided, and the main wall is positioned between the two sets of side walls. The side walls are inclined on both sides of the main wall, and the two sets of side walls are symmetrically arranged on both sides of the main wall. This tundish retaining wall features a slotted design, with the slot located in the middle of the main wall. The width of the slot must accommodate a 70mm allowance on each side of the total width of the retaining wall's front.

[0004] In the existing technology, problems such as cracking, erosion and collapse still occur in the long-term use of slag retaining walls, which affects the smooth slag discharge of the slag retaining walls. Utility Model Content

[0032] The side wall 1 and the middle wall 1 are inclined at an obtuse angle.

[0033] The supporting wall 5 is arranged in a right-angled trapezoidal shape. The supporting wall 5 is symmetrical and parallel to each other. One side of the long side of the supporting wall 5 is connected to one end of the side wall 3. The right-angle end of the side wall 3 is on the same horizontal plane as the bottom of the side wall 3.

[0034] Long trough 7 is located on both sides of the slag retaining wall, and the cross-section of long trough 7 is quadrilateral.

[0035] The side wall 2, side wall 4, and the side wall 3 are inclined at an obtuse angle.

[0036] Example 1: Detailed Description of Basic Structure

[0037] The specific content of this embodiment includes:

[0038] The central wall 1, as the core component of the slag retaining wall, bears the main function of blocking slag. Its design is robust and can withstand the impact of high temperatures and slag.

[0039] Side wall 12 is located on both sides of the central wall and is closely connected to the central wall, which enhances the overall stability of the retaining wall.

[0040] Side wall 3 is connected to one side of side wall 2, further expanding the protection range of the slag retaining wall.

[0041] Side wall 2 4 is located on the other side of side wall 3, and together with the middle wall and side wall 1, it forms a complete slag retaining wall structure.

[0042] The support wall 5 is set at the bottom of one end of the side wall 3 to support and stabilize the slag retaining wall, preventing it from tilting or collapsing due to slag accumulation.

[0043] The elliptical through-hole 6 is installed at the bottom of one end of the side wall 2 as a turbulence hole, which helps to disperse the impact force of the slag and protect the slag retaining wall structure from damage.

[0044] Long groove 7: Embedded on one side of side wall 24, used to fill dry material to facilitate the installation and disassembly of the slag retaining wall, thus improving its convenience.

[0045] Example 2: Enhanced Protective Performance

[0046] Based on Example 1, this example further enhances the protective performance of the slag retaining wall:

[0047] Multiple steel flow holes 11 are provided at one end of the middle wall 1 to allow molten steel to pass through smoothly while reducing the carrying of slag.

[0048] Impact-resistant metal ring 12: Set on the outer wall of the steel flow hole 11, it is made of high-strength, wear-resistant metal material, which effectively resists the impact of slag and molten steel and extends the service life of the slag retaining wall.

[0049] Example 3: Optimized slag outlet design

[0050] This embodiment features an optimized design for the slag outlet of the slag retaining wall, as described in claim 3:

[0051] Slag discharge port 31: Slag discharge ports are provided at the top of both the central wall 1 and the side wall 3 to facilitate the discharge of slag. The projected surface of the slag discharge port is set in an inverted trapezoidal shape, which helps the slag to slide down smoothly and reduces the risk of blockage.

[0052] Example 4: Design of turbulence holes and inclined side walls

[0053] This embodiment optimizes the tilt angles of the turbulence holes and the sidewalls, as described in claim 4:

[0054] The elliptical through holes 6 serve as turbulence holes, and are arranged symmetrically in multiple positions to effectively disperse the impact force of slag. At the same time, they disturb the molten steel at the bottom of the slag retaining wall, increasing the movement and upward floating of the slag at the bottom.

[0055] The side walls of side wall 1 and side wall 2 are inclined at an obtuse angle to the middle wall 1, which helps to guide the waste to slide down the wall and reduce accumulation.

[0056] Example 5: Optimization of Support Wall Structure

[0057] This embodiment optimizes the structure of the supporting wall, as described in claim 5:

[0058] Support wall 5: The overall structure is arranged in a right-angled trapezoid, symmetrical and parallel to each other, which enhances the stability of the retaining wall. One side of the support wall is tightly connected to one end of the side wall 3 to ensure that the retaining wall will not tilt or collapse when subjected to the impact of slag.

[0059] Example 6: Optimization of Long Slot Design

[0060] This embodiment optimizes the design of the elongated slot, as described in claim 6:

[0061] The long groove 7 is located on both sides of the slag retaining wall, and its cross-section is quadrilateral, which facilitates the installation and disassembly of the slag retaining wall components and improves construction efficiency.

[0062] The side wall 4 of side wall 2 is inclined at an obtuse angle to the side wall 3, which helps to guide the slag to slide down the wall and further reduce the accumulation of slag on the retaining wall.

[0063] The above embodiments are only for illustrating the technical concept of this utility model and should not be construed as limiting the scope of protection of this utility model. Any modifications made to the technical solution based on the technical concept proposed by this utility model shall fall within the scope of protection of this utility model.
