[0003] According to the different air permeability channels, ladle air bricks can be further divided into dispersed ladle air bricks, straight-through directional ladle air bricks and slit directional ladle air bricks. The main function of ladle air bricks is to accelerate the decomposition reaction of oxides and impurities in molten steel during the smelting process, promote the removal of impurities and degassing of molten steel, and at the same time, it can also optimize the composition and quality of molten steel, and improve the smelting efficiency and mechanical properties of steel.

[0004] The structure of the existing ladle air bricks mostly includes a brick core and a steel shell. Due to the material difference between the brick core and the steel shell, the steel shell needs to be cast outside the pre-formed brick core. Due to the large volume of the ladle air bricks themselves, the conventional two-half mold makes it difficult for the gas to escape during the casting of the ladle air bricks, resulting in molten steel splashing out of the mold during the casting process. The presence of gas causes uneven distribution of the molten steel, which in turn causes uneven casting of the steel shell of the ladle air brick, which easily makes it difficult to demold the ladle air brick after casting and affects the quality of the ladle air bricks.

[0016] Compared with the prior art, the present invention provides a breathable brick casting and forming equipment and a ladle breathable brick casting and forming process, which have the following beneficial effects: 1. In the air-permeable brick casting and forming equipment, the movable limit seat moves toward one side of the fixed limit seat, and limits the casting mold located at the top of the lifting support between the movable limit seat and the fixed limit seat, and drives the protective plates arranged on both sides of the movable limit seat to isolate the casting mold from the outside of the fixed support, thereby effectively avoiding the safety hazard caused by the heat generated by the casting escaping to the outside of the protective plate, and restricting the movement of the lifting support and the carried casting mold along the direction of the transfer track, so that the lifting support can only drive the casting mold to lift, and the casting port at the top of the casting mold is combined with the casting head of the casting feeding mechanism, and the casting insulation mechanism provides a quantitative amount of still fluid casting raw materials from the casting head to the inside of the casting port, thereby ensuring the alignment between the casting port and the casting head of the casting mold, ensuring that the flow direction of the casting raw materials can only be poured into the inside of the casting port, and effectively ensuring the accuracy of the casting amount while avoiding the escape of the cast casting raw materials and avoiding the hazards such as splashing of the casting raw materials.

[0017] 2. This type of breathable brick casting and forming equipment can accurately control the moving direction of the movable limit seat under the dual limit of the limit rail and each positioning guide rod, and can ensure that when the movable limit seat and the fixed limit seat are in the closest state, they can fit with the lifting support through the lateral side of the movable limit groove, thereby ensuring that when the fixed limit seat and the movable limit seat are in the closest state, the lifting support is restricted in the lateral direction, so that the lifting support can only move up and down in the space formed by the fixed limit seat and the movable limit groove under the drive of the lifting hydraulic cylinder with the casting mold, and at the same time ensure the position of the casting mold. The gap between the fixed limit seat and the movable limit seat is completely covered by the protective plate, effectively preventing heat from directly dissipating to the outside of the protective plate, and at the same time avoiding the escape of the cast casting material, avoiding the splashing of the casting material and other hazards.

[0018] 3. In the process of lifting the casting mold to approach the casting head, the movable injection head extends from the casting port and abuts against the sealing plate. After the injection telescopic rod is fully compressed, the movable injection head drives the sealing plate to overcome the elastic force generated by the extension of the sealing telescopic rod and detach from the sealing groove, so as to connect each casting flow channel with the casting cavity. The casting material enters the casting cavity from the fixed connecting head along the movable injection head and through each casting flow channel, so that the casting material can be gradually filled into the casting cavity until the bottom ends of the casting material sealing plates in the casting cavity are in contact with each other, and the sealing telescopic rod can be driven to shorten, so as to drive the sealing plate to enter the sealing groove to close the casting cavity. At this time, the movable injection head no longer provides casting material, but can effectively ensure the accuracy of the casting amount. At the same time, the pressure generated by the movable injection head can promote the downward flow and complete filling of the casting material in the casting cavity inside the casting mold, thereby ensuring the integrity of the breathable brick produced by the casting.

[0025] During specific use, first prepare the casting raw materials (pre-prepare, adjust or refine the casting raw materials such as molten steel, molten aluminum, etc. according to the actual type of breathable bricks), and pre-input the mixed casting raw materials into the casting insulation mechanism 6 for insulation to maintain the fluidity of the casting raw materials, and prepare in advance a number of casting molds 8 that have been assembled and pre-placed with brick cores, and then move a casting mold 8 with a pre-placed brick core into the top of the lifting support 5 by the transfer track 4, and then drive the movable limit seat 3 to move to one side of the fixed limit seat 2, and limit the casting mold 8 located at the top of the lifting support 5 between the movable limit seat 3 and the fixed limit seat 2, and drive the protective plates 31 arranged on both sides of the movable limit seat 3 to isolate the casting mold 8 from the outside of the fixed support 1, thereby effectively avoiding the safety hazard caused by the heat generated by the casting escaping to the outside of the protective plates 31, and limit the movement of the lifting support 5 and the casting mold 8 carried along the direction of the transfer track 4, so that the lifting support 5 The pouring mold 8 can only be driven to lift, and the pouring port 81 at the top of the pouring mold 8 is combined with the pouring head 71 of the pouring feeding mechanism 7, and the pouring insulation mechanism 6 provides a certain amount of pouring raw materials that are still fluid and are injected into the pouring port 81 from the pouring head 71, so as to ensure the alignment between the pouring port 81 of the pouring mold 8 and the pouring head 71, and ensure that the flow direction of the pouring raw materials can only be poured into the pouring port 81, while effectively ensuring the accuracy of the pouring amount, avoiding the escape of the poured pouring raw materials, and avoiding the hazards such as splashing of the pouring raw materials. After the pouring is completed, when the pouring port 81 is separated from the pouring head 71, the pouring head 71 is closed so that the pouring raw materials stop being output from the pouring head 71, and the pouring mold 8 after the pouring is completed is output along the transfer track 4, and then the next pouring mold 8 with a brick core placed in advance is placed, and the pouring operation of the next pouring mold 8 with a brick core placed in advance is continued until the pouring process of a batch of breathable bricks is completed. Example

[0026] See also Figure 1-Figure 4 The difference from the above embodiment is that a lifting groove 11 is provided on the side of the top of the fixed support 1 close to the fixed limit seat 2, a limiting track 12 is provided on the top of the fixed support 1 and on the side of the lifting groove 11 away from the fixed limit seat 2, the lifting support 5 is arranged inside the lifting groove 11, the movable limit seat 3 is slidably connected with the limiting track 12, and the limiting track 12 can limit the moving direction of the movable limit seat 3.

[0027] A positioning limit seat 13 is also provided at the end of the fixed support 1 away from the fixed limit seat 2, and a plurality of positioning guide rods 14 are provided between the positioning limit seat 13 and the fixed limit seat 2, and the plurality of positioning guide rods 14 all pass through the movable limit seat 3, and a positioning drive rod 15 is provided in the center of the positioning limit seat 13, and the movable end of the positioning drive rod 15 is fixed to the movable limit seat 3; the protective plates 31 on both sides of the movable limit seat 3 extend from the movable limit seat 3 to the side close to the fixed limit seat 2, and when the fixed limit seat 2 and the movable limit seat 3 are in the closest state, the protective plates 31 can completely cover the gap between the fixed limit seat 2 and the movable limit seat 3.

[0028] A connecting groove 51 is provided at the top of the lifting support 5, and a plurality of lifting hydraulic cylinders 52 are provided at the bottom of the lifting support 5, and the lifting hydraulic cylinders 52 can drive the lifting support 5 to move up and down; a receiving track 53 is provided inside the connecting groove 51, and when the lifting support 5 is at the lowest point, the receiving track 53 is aligned with the transfer track 4; a movable limit groove 32 is provided on one side of the movable limit seat 3 close to the fixed limit seat 2; when the fixed limit seat 2 and the movable limit seat 3 are in the closest state, the lifting support 5 can carry the casting mold 8 and move up and down in the space formed by the fixed limit seat 2 and the movable limit groove 32 under the drive of the lifting hydraulic cylinder 52.

[0029] Therefore, when in use, through the setting of the limiting rail 12, and each positioning guide rod 14 passes through the movable limiting seat 3, so that the moving direction of the movable limiting seat 3 can be accurately controlled under the dual limitation of the limiting rail 12 and each positioning guide rod 14, and it can be ensured that when the movable limiting seat 3 and the fixed limiting seat 2 are in the closest state, the lateral side of the movable limiting groove 32 can fit with the lifting support 5, thereby ensuring that when the fixed limiting seat 2 and the movable limiting seat 3 are in the closest state, the lifting support 5 The seat 5 is restricted in the lateral direction (the direction of the receiving track 53 and the transfer track 4), so that the lifting support 5 can only move up and down in the space formed by the fixed limiting seat 2 and the movable limiting groove 32 under the drive of the lifting hydraulic cylinder 52, while ensuring the position of the casting mold 8. At the same time, the protective plate 31 completely covers the gap between the fixed limiting seat 2 and the movable limiting seat 3, effectively preventing heat from directly escaping to the outside of the protective plate 31, and at the same time preventing the cast casting material from falling out, avoiding the splashing of the casting material and other hazards; The lifting support 5 is driven to move up and down by the lifting hydraulic cylinder 52. When the lifting support 5 is at the lowest point, the receiving track 53 and the transfer track 4 are aligned, thereby ensuring the smooth movement of the casting mold 8 between the receiving track 53 and the transfer track 4, and ensuring the mold closing effect between the fixed limit seat 2 and the movable limit seat 3.

[0030] The pouring and heat preservation mechanism 6 includes a storage tank 61 and a pressurizing tank 62. The pressurizing tank 62 is connected to the top of the storage tank 61 by a pipeline. The pouring feeding mechanism 7 also includes a feeding pipe 72. A heating wire is embedded in the feeding pipe 72. The two ends of the feeding pipe 72 are respectively connected to the bottom end of the storage tank 61 and the top of the pouring head 71. The pressurizing tank 62 can input inert gas into the top of the storage tank 61 to drive the pouring raw materials inside the storage tank 61 to be transported along the feeding pipe 72 to the pouring head 71.

[0031] Therefore, through the action of the pressurized tank 62, the pouring material inside the storage tank 61 can be driven by the inert gas to be transported along the feed pipe 72 to the pouring head 71, thereby avoiding the problem of insufficient output power caused by residual pouring material in conventional pumping, ensuring the accuracy of the pouring amount, and effectively avoiding the formation of gaps inside the produced breathable bricks due to insufficient pouring amount. Example

[0032] See also Figure 1-Figure 8 , which is different from the above-mentioned embodiments, is that the casting mold 8 includes a bottom support plate 82, a plurality of lower clamping plates 83, a plurality of side support plates 84 and a top clamping plate 85, a plurality of lower clamping plates 83 are arranged around the top of the bottom support plate 82, and each lower clamping plate 83 is sealed with adjacent lower clamping plates 83 and bottom support plate 82; a plurality of side support plates 84 are respectively arranged inside each lower clamping plate 83, a top clamping plate 85 is arranged inside the top of the casting cavity surrounded by each side support plate 84, and a casting port 81 is opened at the center of the top of the top clamping plate 85.

[0033] Any two opposite lower clamping plates 83 are temporarily fixed by screws, and any two opposite side support plates 84 are temporarily fixed by screws; a limiting connecting rod 86 is arranged on the outside of the pouring port 81, and a limiting column 87 is arranged on the outside of the side support plate 84, and the limiting connecting rod 86 and the limiting column 87 can be temporarily fixed by screws; before the pouring mold 8 is assembled, a brick core is placed inside the pouring cavity in advance; after the pouring mold 8 is assembled, the pouring port 81 serves as the only opening of the pouring cavity.

[0034] Therefore, when in use, the casting mold 8 is assembled by a bottom support plate 82, a plurality of lower clamping plates 83, a plurality of side support plates 84 and a top clamping plate 85, and any two opposite lower clamping plates 83 are temporarily fixed by screws, any two opposite side support plates 84 are temporarily fixed by screws, and the limiting connecting rod 86 and the limiting column 87 can be temporarily fixed by screws, so that the casting mold 8 is stably fixed and closed, and a brick core can be placed in the casting cavity in advance during the assembly process to avoid excessive heat loss caused by an excessively large opening of the casting port 81. In actual use, a fire-proof lining such as soft asbestos is used to ensure the sealing of the casting mold 8 after assembly, and further ensure that after the casting mold 8 is assembled, the casting port 81 is the only opening of the casting cavity, which fully limits the flow range of the casting raw materials and can produce structurally complete breathable bricks.

[0035] A sealing groove 851 is provided in the center of the bottom surface of the top clamp 85, and a plurality of telescopic holes 852 are provided inside the sealing groove 851 and outside the pouring port 81. A sealing telescopic rod 853 is provided inside the telescopic holes 852. A sealing plate 854 is provided at the end of the sealing telescopic rod 853 away from the top of the telescopic hole 852, and a pouring channel 855 is provided at the top of a side surface of the sealing plate 854 close to the pouring port 81; the pouring head 71 includes a fixed connecting head 711 and a movable injection head 712, and the movable injection head 712 is movably connected to the fixed connecting head 711 by the injection telescopic rod 713.

[0036] When the casting mold 8 is lifted and approaches the casting head 71, the movable injection head 712 extends from the casting port 81 and abuts against the sealing plate 854, driving the sealing plate 854 to overcome the elastic force of the sealing telescopic rod 853 and detach from the sealing groove 851, connecting each casting channel 855 with the casting cavity, and the casting material enters the casting cavity from the fixed connecting head 711 along the movable injection head 712 and through each casting channel 855; when the casting material inside the casting cavity is gradually saturated, the casting material exerts upward pressure on the sealing plate 854, driving the sealing plate 854 to enter the sealing groove 851, and close the casting cavity.

[0037] Therefore, when in use, when the casting mold 8 is lifted and approached to the casting head 71, the movable injection head 712 extends from the casting port 81 and abuts against the sealing plate 854. After the injection telescopic rod 713 is fully compressed, the movable injection head 712 drives the sealing plate 854 to overcome the elastic force generated by the extension of the sealing telescopic rod 853 and detach from the inside of the sealing groove 851, so that each casting flow channel 855 is connected with the casting cavity. The casting material enters the casting cavity from the fixed connecting head 711 along the movable injection head 712 and through each casting flow channel 855, so that the casting material can be gradually filled into the casting cavity until the bottom ends of the casting material sealing plates 854 inside the casting cavity are in contact, and the sealing telescopic rod 853 can be driven to shorten. The driving sealing plate 854 enters the sealing groove 851 to close the casting cavity (in the above process, part of the casting material will be retained in each casting channel 855, and the amount of this part of the casting material is negligible relative to the overall casting material amount. And because the amount is small, after the casting mold 8 is disassembled, the driving sealing plate 854 can be directly knocked to remove it, which will not affect the integrity of the breathable brick produced by casting). At this time, the movable injection head 712 no longer provides casting material, but can effectively ensure the accuracy of the pouring amount. At the same time, the pressure generated by the movable injection head 712 can promote the downward flow and complete filling of the casting material in the casting cavity inside the casting mold 8, thereby ensuring the integrity of the breathable brick produced by casting.
