Description

Technical Field

[0001] This utility model relates to the field of refractory equipment technology, specifically a new type of steel spout for teapot packaging. Background Technology

[0002] In the field of refractory equipment technology, the teapot ladle pouring nozzle is an indispensable key component in the steel smelting process. Its performance directly affects the smelting results and the quality of steel. Refractory equipment needs to have excellent high temperature resistance and corrosion resistance to cope with the harsh working conditions of high temperature and complex chemical substances. During the steel pouring process, the teapot ladle pouring nozzle is exposed to the scouring and corrosive environment of high temperature molten steel for a long time, so its refractory performance requirements are extremely high.

[0003] Traditional steel pouring gates for teapot ladles have revealed many problems in practical use. On the one hand, the molten steel flow is not good. The existing gate design cannot guarantee a stable and smooth flow of molten steel during the pouring process, and uneven flow rate often occurs. This not only affects the filling effect of molten steel, leading to defects in the castings, but also reduces production efficiency. On the other hand, there are defects in slag treatment. During the pouring of molten steel, slag is easily mixed into the molten steel and enters the mold along with the molten steel, which seriously affects the quality of the steel. In addition, the existing gates are difficult to effectively separate slag from molten steel and lack a proper mechanism for treating slag.

[0004] In summary, existing teapot-shaped steel pouring nozzles have significant shortcomings in terms of molten steel diversion and slag treatment, and there is an urgent need for a new type of teapot-shaped steel pouring nozzle to solve these problems in order to meet the growing demand for high-quality production in the steel smelting industry. Utility Model Content

[0005] The purpose of this invention is to provide a novel steel spout for pouring molten steel into a teapot, in order to solve the problems of poor molten steel flow and the inability to separate molten steel slag from molten steel mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a novel steel spout for teapot pouring, comprising a pouring pipe, wherein a functional cavity is provided at the lower end of the pouring pipe, and an external discharge port is provided at the lower end of the functional cavity; an overflow plate is fixedly provided on the inner bottom surface of the functional cavity, and a scraper plate is fixedly provided on the inner top surface of the functional cavity; an installation cylinder is fixedly provided on the lower outer surface of the functional cavity, and a pouring core is connected to the inner surface of the installation cylinder;

[0007] The casting core has a flow guide cavity inside, and a flow guide plate is fixedly installed on the lower outer surface of the casting core. The flow guide plate has a flow guide port inside. The side surface of the casting core has a ventilation groove inside, and an overflow prevention pipe is fixedly installed on the outer surface of the casting core.

[0008] Preferably, the functional cavity is a frustum-shaped design with different diameters at both ends, and the smaller diameter end of the functional cavity is fixedly connected to the casting pipe, and the smaller diameter end of the functional cavity is connected to the casting pipe.

[0009] The above technical solution helps guide molten steel to flow smoothly from the pouring pipe into the functional cavity. The frustum-shaped structure can play a preliminary role in converging the molten steel, making the molten steel more evenly distributed in the functional cavity, laying a good foundation for subsequent flow and processing.

[0010] Preferably, the external discharge port is located at the end with the larger diameter of the functional cavity, and the external discharge port is eccentrically positioned relative to the end with the larger diameter of the functional cavity.

[0011] By adopting the above technical solution, the eccentrically set external discharge port can change the direction and speed of molten steel flowing out of the functional cavity, avoid the molten steel directly impacting the lower component vertically, and make the molten steel rotate or deflect to a certain extent when flowing out, which helps to better cooperate with the subsequent guiding cavity and improve the stability and uniformity of molten steel diversion.

[0012] Preferably, the overflow plate and the slag scraper are arranged facing each other vertically, and the overflow plate and the slag scraper are staggered, with the slag scraper facing the external discharge port.

[0013] Using the above technical solution, the overflow plate can initially block the steel slag, preventing it from flowing with the molten steel in large quantities. The slag scraper further blocks the steel slag. The staggered and opposite arrangement of the two forms a double blocking mechanism. Moreover, the slag scraper is facing the external discharge port, which can effectively prevent the steel slag from flowing out of the external discharge port, thereby achieving efficient separation of steel slag and molten steel, ensuring the purity of the molten steel, and improving the quality of the steel.

[0014] Preferably, the guide cavity is designed as a flared opening with different diameters at both ends, with the larger diameter end facing the external outlet and connected to it. The smaller diameter end of the guide cavity is positioned opposite the guide plate, which has a downward-facing arc shape. The guide opening has a downward-facing V-shaped design, with its lower end penetrating the lower end face of the guide plate, and its upper end facing the guide cavity.

[0015] By adopting the above technical solution, the funnel-shaped guide cavity can gather and guide the molten steel flowing out from the outer outlet, making the molten steel flow rate more uniform. The arc-shaped guide plate can buffer the impact force of the molten steel and change the flow direction of the molten steel. The V-shaped guide port further guides the molten steel to flow out stably and smoothly, avoids turbulence, effectively improves the filling effect of molten steel, reduces casting defects, and improves production efficiency.

[0016] Preferably, the lower end of the venting groove penetrates the inner top surface of the guide cavity, and the upper end of the venting groove is connected to the overflow prevention pipe, and the overflow prevention pipe is set upwardly at an angle to the functional cavity.

[0017] By adopting the above technical solution, if the molten steel pressure is too high or an abnormal situation occurs during the molten steel pouring process, the excess molten steel can flow into the anti-overflow pipe through the venting groove to prevent the molten steel from overflowing and ensure the safety of the pouring process. When the molten steel is flowing normally, the venting groove and the anti-overflow pipe can balance the pressure inside the guide cavity to ensure the stability and smoothness of the molten steel flow.

[0018] Compared with the prior art, the beneficial effects of this utility model are: the new teapot has a steel spout for pouring.

[0019] 1. The guide cavity of the pouring spout for the teapot ladle is designed as a flared shape with different diameters at both ends. The larger diameter end faces the external outlet and is connected to it, while the smaller diameter end faces the arc-shaped guide plate. The guide opening is a V-shape with the tip pointing downwards. This structural design can guide the molten steel to flow more stably and smoothly. When the molten steel enters the guide cavity from the functional cavity through the external outlet, the flared shape can converge and guide the molten steel, making the flow rate of the molten steel more uniform during the pouring process. This effectively avoids casting defects caused by uneven molten steel flow rate, improves the filling effect of molten steel, and thus improves production efficiency.

[0020] 2. The overflow plate and slag scraper inside the functional cavity are arranged opposite each other and staggered. Since the density of steel slag is less than that of molten steel, the steel slag will float on the surface of the molten steel during pouring. When the molten steel flows, the overflow plate can stop the steel slag, and the slag scraper can block the steel slag, preventing it from flowing directly out of the external outlet with the molten steel. This double blocking effect effectively separates the steel slag from the molten steel, reduces the situation of steel slag mixing into the molten steel and entering the mold, and ensures the quality of the steel.

[0021] 3. During the molten steel pouring process, if the molten steel pressure is too high or an abnormal situation occurs, the excess molten steel can enter the anti-overflow pipe through the venting groove to prevent molten steel from overflowing. This ensures the safety and stability of the pouring process, prevents molten steel overflow from causing damage to equipment and personnel, and ensures the safety of the production environment. During the normal flow of molten steel, the venting groove and anti-overflow pipe can balance the pressure inside the guide cavity, further ensuring the smooth flow of molten steel.

[0029] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0030] Please see Figures 1-6 This utility model provides a technical solution: a novel steel spout for pouring teapots.

[0031] Example 1

[0032] This embodiment discloses: a casting pipe 1, a functional cavity 2 is provided in the lower end of the casting pipe 1, and an external discharge port 3 is opened at the lower end of the functional cavity 2. An overflow plate 4 is fixedly provided on the inner bottom surface of the functional cavity 2, and a scraper plate 5 is fixedly provided on the inner top surface of the functional cavity 2. An installation cylinder 6 is fixedly provided on the lower outer surface of the functional cavity 2, and a casting core 7 is connected to the inner side surface of the installation cylinder 6.

[0033] The functional cavity 2 is a frustum-shaped design with different diameters at both ends. The smaller diameter end of the functional cavity 2 is fixedly connected to the casting pipe 1, and the smaller diameter end of the functional cavity 2 is connected to the casting pipe 1.

[0034] The external discharge port 3 is located at the end of the functional cavity 2 with a larger diameter, and the external discharge port 3 is eccentrically positioned relative to the end of the functional cavity 2 with a larger diameter.

[0035] The overflow plate 4 and the slag scraper 5 are arranged facing each other vertically, and the overflow plate 4 and the slag scraper 5 are staggered, with the slag scraper 5 facing the external discharge port 3.

[0036] During the pouring of molten steel in steel smelting, the molten steel enters the functional cavity 2 through the pouring pipe 1. The functional cavity 2 is designed in the shape of a frustum, with the smaller diameter end connected to the pouring pipe 1. This structure facilitates the smooth flow of molten steel into the functional cavity 2. Since the external discharge port 3 is located at the larger diameter end of the functional cavity 2 and is eccentrically positioned, the flow path of the molten steel within the functional cavity 2 is more rational. During the flow of molten steel, the overflow plate 4 and the slag scraper 5 play crucial roles. Because the density of steel slag is less than that of molten steel, it floats on the surface of the molten steel. The overflow plate 4 can initially block the steel slag, preventing it from flowing rapidly with the molten steel. The slag scraper 5 is vertically opposed to the overflow plate 4 and staggered, while also facing the external discharge port 3, further blocking the steel slag and making it difficult for it to flow out of the external discharge port 3. This achieves the initial separation of steel slag and molten steel, ensuring the purity of the molten steel entering subsequent processes and improving the quality of the steel. The installation cylinder 6 is used to connect the casting core 7, providing a guarantee for the stable installation of the entire pouring gate.

[0037] Example 2

[0038] This embodiment discloses, based on embodiment 1, that: a flow guide cavity 8 is provided inside the casting core 7, and a flow guide plate 9 is fixedly provided on the lower outer surface of the casting core 7, and a flow guide port 10 is provided inside the flow guide plate 9, a ventilation groove 11 is provided inside the side surface of the casting core 7, and an anti-overflow pipe 12 is fixedly provided on the outer surface of the casting core 7.

[0039] The flow guide cavity 8 is designed with a flared mouth with different diameters at both ends. The end with the larger diameter of the flow guide cavity 8 faces the external outlet 3 and is connected to the external outlet 3. The end with the smaller diameter of the flow guide cavity 8 is positioned facing the flow guide plate 9. The flow guide plate 9 has an arc-shaped design with the opening facing downwards. The flow guide port 10 has a V-shaped design with the tip facing downwards. The lower end of the flow guide port 10 penetrates the lower end face of the flow guide plate 9, and the upper end of the flow guide port 10 is positioned facing the flow guide cavity 8.

[0040] The lower end of the venting groove 11 penetrates the inner top surface of the guide cavity 8, and the upper end of the venting groove 11 is connected to the overflow pipe 12, and the overflow pipe 12 is set upward obliquely towards the functional cavity 2.

[0041] Molten steel flowing from functional cavity 2 through external outlet 3 enters guide cavity 8. Guide cavity 8 is funnel-shaped, with its larger diameter end facing and connected to external outlet 3, which can converge and guide the molten steel, making the flow rate of molten steel more uniform during pouring. When the molten steel flows along guide cavity 8 to the smaller end, it will impact the arc-shaped guide plate 9. The guide port 10 is a V-shape with the tip pointing downwards and penetrates the lower end face of guide plate 9, with its upper end facing guide cavity 8. This structural design can further guide the molten steel to flow out stably and smoothly, avoiding casting defects caused by uneven molten steel flow rate. To address defects and improve the filling effect and production efficiency of molten steel, if the molten steel pressure is too high or an abnormal situation occurs during the molten steel pouring process, excess molten steel can enter the overflow prevention pipe 12 through the venting groove 11. The lower end of the venting groove 11 penetrates the top surface inside the guide cavity 8, and the upper end is connected to the overflow prevention pipe 12. The overflow prevention pipe 12 is set upwards at an angle towards the functional cavity 2. This not only avoids damage to equipment and personnel caused by molten steel overflow, ensuring the safety and stability of the pouring process, but also balances the internal pressure of the guide cavity 8 when the molten steel is flowing normally, further ensuring smooth molten steel flow.

[0042] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
