Description

Technical Field

[0001] This utility model relates to the field of breathable core brick technology, and in particular to a directional slit type breathable core brick. Background Technology

[0002] As societal demands continue to rise, steel companies are constantly upgrading their products to improve the purity and uniformity of steel composition. Ladle refining in the steelmaking process has a decisive impact on steel quality. To promote inclusion flotation and alloy uniformity, inert gas is blown into the molten steel through permeable bricks installed at the bottom of the ladle during refining. This achieves uniform steel composition and temperature, promotes inclusion growth and flotation, and purifies the molten steel. Therefore, permeable bricks are key components in ladle refining, and their blowing rate and permeability determine the successful implementation of ladle refining.

[0003] Currently, the most commonly used type is the slotted permeable brick. The slots are typically distributed in 1-3 radial rings centered on the cross-section center. Each slot is usually strip-shaped, with a length of approximately 15mm. When the length of a slot is blocked by steel slag or cold steel, it can only be repaired after use through high-intensity oxygen combustion.

[0004] Therefore, it is necessary to provide a directional slotted permeable core brick to solve the above-mentioned technical problems. Utility Model Content

[0005] This invention provides a directional slotted permeable core brick, which solves the problems in the background art.

[0006] To solve the above-mentioned technical problems, this utility model provides a directional slotted permeable core brick, including a permeable brick body. The permeable brick body has an upper steel cover, a lower steel cover, and a rectangular steel tube inside. The rectangular steel tube is installed through both ends between the upper and lower steel covers. Multiple permeable slots are formed inside the rectangular steel tube and are equidistantly spaced. Adjacent permeable slots are connected by a flow channel. By placing the permeable slots inside the rectangular steel tube, its compressive strength is improved. Furthermore, the interconnected flow channels between each permeable slot simplify operation and change the traditional method of multiple slots not being interconnected. When one permeable slot is blocked, the flow of gas through other channels can clear the blockage. This method is simple to operate and facilitates the normal use of the permeable brick body.

[0007] Preferably, the bottom surface of the upper steel cover is provided with reinforcing ribs, and the bottom end of the reinforcing ribs is provided with the top surface of the lower steel cover. By providing reinforcing ribs, when filling the interior of the permeable brick body with concrete, multiple reinforcing ribs can be welded and fixed between the lower and upper steel covers first, and then the concrete layer is filled between the stainless steel sheet and the rectangular steel pipe, so that the concrete layer buries the reinforcing ribs. This method is simple to operate and facilitates the improvement of the overall compressive strength when the concrete layer solidifies.

[0008] Preferably, the breathable brick body has a brick body inside, and a stainless steel sheet is provided inside the brick body. The stainless steel sheet is wrapped around the outside of the upper and lower steel covers. By providing the stainless steel sheet, the compressive strength of the outside of the breathable brick body can be improved.

[0009] Preferably, a concrete layer is filled between the stainless steel sheet and the rectangular steel pipe. By setting the concrete layer, the overall stability of the permeable brick body can be improved.

[0010] Preferably, multiple reinforcing ribs are provided, and the multiple reinforcing ribs are installed at equal intervals between the upper steel cover and the lower steel cover. By providing multiple reinforcing ribs, it is easy to improve the overall compressive strength of the breathable brick body.

[0011] Preferably, the internal width of the ventilating slit is equal to the internal width of the flow channel. By setting the internal width of the ventilating slit to be the same as the internal width of the flow channel, it is easier to clear the ventilating slit.

[0012] Compared with related technologies, the directional slotted permeable core brick provided by this utility model has the following beneficial effects:

[0013] Compared with existing technologies, this type of directional slotted permeable core brick improves its compressive strength by opening permeable slots inside a rectangular steel tube. Furthermore, each permeable slot is interconnected via flow channels, simplifying operation. This method changes the traditional approach where multiple slots are not interconnected, allowing the flow of gas through other channels to clear blockages in one slot. This simplifies operation and facilitates normal use of the permeable brick. By incorporating reinforcing ribs, multiple ribs can be welded and fixed between the lower and upper steel caps before filling the concrete layer inside the permeable brick. Then, the concrete layer is filled between the stainless steel sheet and the rectangular steel tube, burying the reinforcing ribs. This simple operation also improves the overall compressive strength as the concrete solidifies.
