Description

Technical Field

[0001] The utility model relates to the field of refractory material production, in particular to a slag blocking rod forming die. Background Art

[0002] Slag stoppers are commonly used in refractory production. For example, steelmaking converters often use a combination of a slag stop cone and a slag guide rod (i.e., a slag stopper). Existing slag stoppers primarily consist of steel bars (typically 10-18 mm in diameter) and a refractory rod (typically 700-1600 mm in diameter) cast from refractory material, with a portion of the steel bar positioned within the rod. Traditional slag stopper production methods typically rely on single rod production, often requiring dozens or even hundreds of molds for rotational production. This is costly and inefficient. To overcome these issues, there are reports of methods for producing multiple slag stoppers at once. For example, CN215038563U discloses a mold for producing slag stoppers. This mold requires multiple secondary cylinders and multiple primary cylinders, resulting in high production costs and still preventing mass production of slag stoppers. Therefore, designing a slag stopper forming mold that not only enables mass production of slag stoppers, but also offers low cost and convenient retrieval of finished products is crucial. Summary of the Invention

[0003] In view of this, the utility model proposes a slag stopper rod forming mold, which has a simple and ingenious structure, low mold cost, can also realize batch production of slag stopper rods, and the number of slag stopper rods formed at one time can be flexibly adjusted.

[0020] The following is a detailed description of an embodiment of the present invention in conjunction with the accompanying drawings. This embodiment is implemented based on the technical solution of the present invention, and provides a detailed implementation method and specific operation process. However, the protection scope of the present invention is not limited to the following embodiment.

[0022] like Figure 1-7 As shown, the slag stopper rod forming mold of the present invention includes a forming structure, a positioning frame and a limiting structure for preventing the forming structure from moving up and down. The positioning frame includes an upper base plate 1a and a lower base plate 1b arranged opposite to each other, and also includes a plurality of legs 1c connecting the upper base plate 1a and the lower base plate 1b together. The legs 1c are made of H-shaped steel or channel steel to provide a stable and reliable support foundation for the forming structure; the upper base plate 1a and the lower base plate 1b are provided with corresponding positioning holes K1, and the diameter of the positioning hole K1 is consistent with the diameter of the steel bar of the slag stopper rod, so that the steel bar passes through the upper base plate 1a and the lower base plate 1b from top to bottom, providing sufficient space for the steel bar;

[0023] The forming structure is vertically arranged on the upper base plate 1a, which includes relatively arranged forming end plates 2a, a plurality of intermediate forming plates 2b spaced apart between the forming end plates 2a, and a connecting unit connecting the forming end plates 2a and the intermediate forming plates 2b together. The forming end plates 2a and the intermediate forming plates 2b are both vertically arranged, and semicircular holes K2 are provided on the inner side surface of the forming end plates 2a and each plate surface of the intermediate forming plates 2b. The semicircular holes K2 correspond to each other in pairs to form circular forming holes K3. A plurality of intermediate forming plates 2b and the forming end plates 2a are pieced together to form multiple rows of forming holes K3. The forming holes K3 correspond to the positioning holes K1 below and are coaxial, ensuring the coaxiality of the steel bars and the refractory section of the slag stop rod; the semicircular holes K2 on both sides of the intermediate forming plate 2b are staggered, so that the two adjacent rows of forming holes K3 are staggered, thereby increasing the number of holes per unit area;

[0024] The connecting unit includes a pair of vertically arranged fixed liner plates 2c. The two fixed liner plates 2c are arranged opposite each other and located on the outside of the formed end plate 2a. A plurality of L-shaped mounting holes 2d are opened from top to bottom on the connecting edge of each fixed liner plate 2c. The mounting holes 2d on each pair of connecting edges of the two fixed liner plates 2c are arranged in pairs. A screw 2e (with a nut) is passed through each pair of mounting holes 2d. Each pair of connecting edges of the two fixed liner plates 2c is fixedly connected together by multiple spaced screws 2e, so that the formed end plate 2a and the intermediate formed plate 2b are connected to form a whole.

[0025] Among them, the mounting hole 2d is an L-shaped structure, so that the screw 2e enters the bottom of the vertical section from its horizontal section, effectively preventing the screw 2e from falling out of the mounting hole 2d on its own, and ensuring the fixing effect of the molding structure.

[0026] The utility model has four limiting structures (or more than four), and each fixed lining plate 2c is fixedly connected to the upper base plate 1a through two limiting structures to ensure a reliable connection between the forming structure and the upper base plate 1a, and avoid the forming structure being separated from the positioning frame during the vibration of the refractory material, which affects the quality of the finished product. Figure 1 As can be seen, the limiting structure includes an articulated seat 3a fixed to the upper base plate 1a and a holder 3b fixed to the fixed liner 2c. The articulated seat 3a is a U-shaped structure, with a horizontal shaft 3c set on the articulated seat 3a. The shaft 3c is fixedly connected to the bolt 3d, and the holder 3b is provided with a slot that cooperates with the bolt 3d. When the forming structure is hoisted into place, the bolt 3d is rotated upward and clamped on the slot. The nut on the bolt 3d is tightened. When the finished slag stop rod is taken out, the nut on the bolt 3d is unscrewed and the bolt 3d is removed from the slot to unlock the limiting structure, making it convenient to remove the fixed liner 2c and facilitate the removal of the finished product.

[0027] The slag stopper rod forming die of the utility model can realize the batch production of slag stopper rods, specifically including:

[0028] Place multiple intermediate forming plates 2b between the forming end plates 2a, as shown in the figure; place the fixed lining plates 2c on both sides of the forming end plates 2a, and then use screws 2e to fix the two fixed lining plates 2c together to assemble the forming structure together; Among them, the intermediate forming plates 2b in the utility model can be flexibly adjusted, and the number of slag blocking rods formed at one time can be adjusted by adjusting the number of intermediate forming plates 2b, thereby achieving flexible production;

[0029] Hoist the forming structure onto the upper base plate 1a so that the forming hole K3 corresponds to the positioning hole K1 below. After adjusting it into place, use multiple limiting structures to securely connect the fixed lining plate 2c and the upper base plate 1a together.

[0030] Lift the connected forming structure and positioning frame onto the vibration platform, place a steel bar into each forming hole K3, and pass the steel bar through the positioning hole K1 of the upper base plate 1a and the positioning plate of the lower base plate 1b from top to bottom. Use the upper base plate 1a and the lower base plate 1b to limit the steel bar. The vibration platform below can provide support for the bottom of the steel bar. The upper part of the steel bar is located in the forming hole K3 to ensure that the refractory material can wrap the steel bar.

[0031] Pour the mixed refractory raw materials into each forming hole K3, adding materials while vibrating; after adding materials and vibrating, move the whole into the kiln for drying; after drying for a period of time, pull it out of the kiln, and when the temperature drops, the mold can be disassembled and the finished products can be taken out of the mold one by one.

[0032] The forming structure of the present invention has multiple rows of forming holes K3, which can realize batch production of slag stop rods, increase output and reduce costs; in addition, the present invention can control the total number of forming holes K3 by adjusting the number of intermediate forming plates 2b, thereby realizing the adjustment of the production quantity of slag stop rods; the positioning frame of the present invention can position the steel bars and provide a space for them. The forming structure is fixed on the positioning frame by a limiting structure, which effectively avoids the up and down movement of the forming structure due to vibration during the forming process, thereby ensuring the forming quality.
