[0002] The long nozzle is one of the three major continuous casting parts. During refractory processing, molten steel is poured from the ladle to the tundish. In order to avoid oxidation and splashing, a long nozzle is usually installed at the lower end of the sliding nozzle at the bottom of the ladle. It mainly prevents the secondary oxidation of molten steel, improves the quality of steel, and reduces the deposition of oxidation products of easily oxidized elements in the steel on the inner wall of the nozzle. It is an important functional refractory material for realizing molten steel protection casting to improve the quality of steel billets. Its use will directly affect whether the entire continuous casting process can proceed normally.

[0003] However, when the inside of the shroud comes into contact with the material, a reaction is likely to occur. The temperature of the shroud material rises sharply, while the outer surface is at room temperature. The product itself generates large thermal stress, which will cause cracks to release the stress, causing the shroud to end its service life in a short time and reduce its service life.

DETAILED DESCRIPTION

[0027] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-4 The utility model provides a technical solution: a long water inlet that is not easy to be blocked, including a connector 1, a port 1 2, a port 2 3, a mesh plate 4, a diverter block 5, a guide plate 6, a connecting rod 7, a rotating paddle 8, a diverter paddle 9, an anti-seismic layer 10, a heat-resistant layer 11, an anti-blocking layer 12, a protective layer 13, and an inner lining layer 14.

[0029] Embodiment 1: The long water inlet which is not easy to be blocked is provided with a flow guiding structure, through which the heat of the logistics entering is buffered, and the circulation is made smoother, thereby increasing the service life, specifically:

[0030] The upper end of the connector 1 is connected to port 1 2, and also includes port 2 3, which is fixedly installed at the lower end of the connector 1. A guide structure is installed inside the connector 1, and the guide structure can divert the material through the diverter block 5 and then cooperate with the rotating paddle 8 to make the material flow downward to avoid blockage. The guide structure includes a mesh plate 4, which is fixedly installed on the inner wall surface of port 1 2, and a diverter block 5 is installed on the upper surface of the mesh plate 4, and a guide plate 6 is fixedly connected to the lower surface of the mesh plate 4. A connecting rod 7 is rotatably installed at the center of the lower surface of the mesh plate 4, and a rotating paddle 8 is fixedly installed on the outer surface of the connecting rod 7. The upper side of the rotating paddle 8 corresponds to the lower end of the guide plate 6, and a diverter paddle 9 is installed at the lower end of the connecting rod 7. The diverter paddle 9 is located inside the port 2 3, and the diverter block 5 is set as a triangular structure, and the guide plate 6 is symmetrically provided with two.

[0031] When the material flows into the long water inlet which is not easy to be blocked, Figure 3 As shown, first, the material will flow in through the port 1-2 connected to the upper end of the connector 1. Since the diverter block 5 is set as a triangular structure, the material will be diverted by the diverter block 5, so that the material flows downward from both sides of the diverter block 5, and then the material will pass through the mesh plate 4, and then flow downward through a slide rail flow plate installed on the lower surface of the mesh plate 4. A connecting rod 7 is rotatably installed at the center of the lower surface of the mesh plate 4, and a rotating paddle 8 is fixedly installed on the outer surface of the connecting rod 7, so the guide plate 6 makes the material impact the rotating paddle 8, so that the rotating paddle 8 rotates, and then the material will flow downward along the rotating paddle 8. Further, when the material flows through the connector 1 and reaches the port 2 3, the material is again diverted by the diverter paddle 9 to avoid blockage at the lower end.

[0032] Embodiment 2: The long shroud which is not easy to be blocked is also provided with a composite reinforcement structure, which can prevent the blockage of materials through multiple layers of materials and reinforce the long shroud as a whole, specifically:

[0033] The inner wall surface of the connector 1 is provided with a composite reinforcement structure, and the composite reinforcement structure avoids internal damage caused by material flow by adding multiple layers of materials. The composite reinforcement structure includes a heat-resistant layer 11, and the heat-resistant layer 11 is installed on the inner wall surface of the port 1 2 above the mesh plate 4. The inner wall surfaces of the connector 1 and the port 1 2 are both provided with a seismic-resistant layer 10, and the inner wall surface of the seismic-resistant layer 10 is provided with an anti-blocking layer 12, and the inner wall surface of the port 2 3 is provided with a protective layer 13, and the inner lining layer 14 is installed inside the interlayer of the port 2 3, and the lining layer 14 is set to a low-carbon material.

[0034] Furthermore, when the material flows, the heat-resistant layer 11 on the inner wall surface of port 12 first contacts the material, and the heat-resistant layer 11 relieves the thermal shock of the material to avoid large thermal stress inside, which may cause cracking. Furthermore, the shock-resistant layer 10 installed on the inner wall surfaces of the connector 1 and port 12 mainly adopts aluminum hydroxide material, which can improve the overall room-temperature flexural strength and thermal expansion coefficient, and the inner wall surface of the shock-resistant layer 10 is provided with an anti-blocking layer 12. The zirconium dioxide in the anti-blocking layer 12 can reduce the adhesion of oxides in the material on the inner surface and inhibit clogging. In addition, the low-carbon material provided on the inner lining layer 14 of port 23 cooperates with the protective layer 13 to relieve the thermal stress of port 23, so that the resistance of the overall long water outlet is enhanced, and it is not easy to be blocked or damaged, thereby improving the adaptability life of the product.

[0035] Working principle: When using the long water inlet that is not easy to be clogged, a guide structure is provided, which can divert the material through the diversion block 5 and then cooperate with the guide plate 6 to make the material flow downward to avoid clogging. The composite reinforcement structure avoids material clogging by adding multiple layers of materials, making the material flow smoother, avoiding internal damage, and increasing the overall practicality.
