Description

Technical Field

[0001] This utility model belongs to the field of iron and steel metallurgy technology, and in particular relates to a directional solidification paving brick. Background Technology

[0002] Currently, due to the unreasonable design of the inner diameter of the directional solidification bottom pouring tank and the mold, the liquid level in the middle pouring tank is too low. If progressive split-type slurry bricks are used, the static pressure of the molten steel is too high, and it is easy for the steel to "penetrate" through the brick joints, resulting in an unstable liquid level in the bottom pouring tank, which can easily affect the safety of pouring and bring safety hazards. Utility Model Content

[0003] The purpose of this invention is to solve the problems of existing slurry bricks being unfavorable for liquid level stability and having low safety. It provides a directional solidification slurry brick that can effectively stabilize the liquid level in the bottom slurry tank, reduce slag entrapment in the middle slurry tank, and improve the internal quality of the ingot.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A type of directional solidification duct brick includes a three-way duct brick and a horizontal duct brick that cooperate with each other. The three-way duct brick includes a horizontal section and a vertical section. The duct of the vertical section is funnel-shaped, and the inner diameter of the duct gradually decreases from the end closer to the horizontal section to the end farther away from the horizontal section.

[0006] The horizontal section is connected to the horizontal slurry brick, and the inner diameter of the horizontal slurry brick is reduced from 80mm to 55mm in order to reduce the amount of steel passing through and make the steel liquid level in the bottom pouring tank more stable.

[0007] Furthermore, the minimum inner diameter of the vertical section of the three-way slab is 55mm.

[0008] Furthermore, the maximum inner diameter of the vertical section of the three-way slab is 80mm.

[0009] Furthermore, a locking mechanism is provided at the connection point of two adjacent horizontal soup bricks. The locking mechanism includes a left locking mechanism and a right locking mechanism that fit together, and the left and right locking mechanisms are respectively located on the left and right sides of a single horizontal soup brick.

[0010] Furthermore, the left bayonet includes a convex section and a concave section. The convex section is close to the outer side of the horizontal soup brick, and the concave section is close to the inner side of the horizontal soup brick. The convex section and the concave section are connected by a slope transition.

[0011] Furthermore, the right bayonet includes an outer concave section and an inner convex section. The outer concave section is close to the outer side of the horizontal soup brick, and the inner convex section is close to the inner side of the horizontal soup brick. The outer concave section and the inner convex section are also connected by a slope transition.

[0012] Furthermore, when two adjacent paving bricks are joined together, the convex section fits perfectly with the concave section, and the concave section fits perfectly with the convex section.

[0013] In the technical solution of this utility model, by designing the inner hole of the vertical section of the three-channel brick into a trumpet shape, the impact of the steel flow on the flow channel is reduced. At the same time, the inner diameter of the horizontal flow channel brick is optimized from 80mm to 55mm, reducing the amount of steel flow and making the steel liquid level in the bottom pouring tank more stable. This compensates for the phenomenon of low liquid level in the bottom pouring tank during casting and improves the situation of "steel penetration" in the brick joint. Attached Figure Description

[0016] Example

[0017] To make this utility model clearer, the following description, in conjunction with the accompanying drawings, further illustrates a directional solidification paving brick of this utility model. The specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of this utility model.

[0018] See Figure 1 ,and Figure 2 A type of directional solidification soup channel brick, comprising a three-way soup channel brick 1 and a horizontal soup channel brick 2 that cooperate with each other, wherein the three-way soup channel brick 1 includes a horizontal section 11 and a vertical section 12, characterized in that:

[0019] The channel 12a of the vertical section 12 is designed in a funnel shape, and the inner diameter of the channel 12a gradually decreases from the end near the horizontal section 11 to the end away from the horizontal section 11. The inner diameter of the vertical section 12 of the three-way slab brick 1 is 55mm at the minimum and 80mm at the maximum.

[0020] The horizontal section 11 is connected to the horizontal slurry brick 2. The inner diameter of the horizontal slurry brick 2 is reduced from 80mm to 55mm in order to reduce the amount of steel passing through and make the steel liquid level in the bottom pouring tank more stable.

[0021] See Figure 2 A latch 21 is provided at the connection between two adjacent horizontal soup bricks 2. The latch 21 includes a left latch 211 and a right latch 212 that fit together. The left and right latches are respectively located on the left and right sides of a single horizontal soup brick 2.

[0022] The left bayonet 211 includes an outwardly convex section 211a and an inwardly concave section 211b. The outwardly convex section 211a is close to the outer side of the horizontal soup channel brick 2, and the inwardly concave section 211b is close to the inner side of the horizontal soup channel brick 2. The outwardly convex section 211a and the inwardly concave section 211b are connected by a slope transition.

[0023] The right bayonet 212 includes an outer concave section 212a and an inner convex section 212b. The outer concave section 212a is close to the outer side of the horizontal soup channel brick 2, and the inner convex section 212b is close to the inner side of the horizontal soup channel brick 2. The outer concave section 212a and the inner convex section 212b are also connected by a slope transition.

[0024] When two adjacent soup bricks 2 are joined together, the convex section 211a fits into the concave section 212a, and the concave section 211b fits into the convex section 212b.

[0025] This invention designs the inner hole of the vertical section of the three-channel brick into a trumpet shape, which reduces the impact of the steel flow on the flow channel. The inner diameter of the horizontal flow channel brick is optimized to 55mm, which reduces the amount of steel flow and makes the steel liquid level in the bottom injection tank more stable.

[0026] In addition to the embodiments described above, this utility model may have other implementations. All technical solutions formed by equivalent substitution or equivalent transformation fall within the protection scope claimed by this utility model.
