Description

Technical Field

[0001] This utility model relates to the field of casting ladles, specifically to a slag-iron separation device for molten steel casting. Background Technology

[0002] When casting molten steel, a container filled with molten steel is used, and then the molten steel is poured into the container to be cast. Since most impurities float on the surface of the molten steel, it is often necessary to use slag removal equipment to clean the impurities on the surface of the molten steel. However, the cleaning process is affected by the skill level of the workers, and the time required varies. This causes the temperature of the molten steel in the container to fluctuate, which affects the quality of the final casting.

[0003] Currently, improvements are being made to the containers holding molten steel. Specifically, filters are often installed at the outlet, or baffles with bottom channels are installed inside the container to prevent impurities floating on the surface of the molten steel from entering the casting container from the outlet. However, filters are prone to clogging, which affects casting efficiency. As for baffles with bottom channels, impurities can still enter the casting container along with the molten steel towards the end of the casting process. If the casting process is stopped too early, molten steel will be wasted. If the casting process is stopped too late, impurities and molten steel will enter the casting container at the same time, affecting the quality of the casting.

[0004] In view of the problems existing in the prior art, this utility model designs and manufactures a slag-iron separation device for molten steel casting to overcome the above defects. Summary of the Invention

[0005] To address the problems existing in the prior art, this utility model provides a steel casting slag-iron separation device that can achieve complete separation of slag and iron.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a molten steel casting slag-iron separation device, including a molten steel container, wherein a main partition is provided in the molten steel container, the main partition divides the molten steel container into a main cavity and an auxiliary cavity, and a main channel is provided between the bottom of the main partition and the bottom of the molten steel container, the main channel being able to connect the main cavity and the auxiliary cavity; The auxiliary cavity is provided with a casting nozzle on the side away from the main cavity at the upper end. An auxiliary partition is provided in the auxiliary cavity. The auxiliary partition is close to the casting nozzle and is perpendicular to the auxiliary cavity side wall away from the main cavity. An auxiliary channel is provided between the auxiliary partition and the auxiliary cavity side wall away from the main cavity. The auxiliary channel can connect the chamber close to the casting nozzle and the chamber below the auxiliary cavity. The auxiliary partition is provided with a filter plate limiting structure, on which a filter plate can be detachably installed.

[0007] Preferably, the filter plate limiting structure is a boss that extends from the outer edge of the auxiliary cavity to the bottom of the auxiliary cavity, and the boss is provided with a slot in which the filter plate can be placed and the filter plate can cover the auxiliary channel.

[0008] Preferably, the height of the auxiliary partition is greater than the height of the auxiliary channel.

[0009] Preferably, the auxiliary partition is an arc-shaped plate, and the middle position of the arc-shaped plate is recessed towards the casting nozzle.

[0010] Preferably, two auxiliary partitions are arranged in parallel, and the filter plate limiting structure is set as the interval between the two auxiliary partitions, with the filter plate disposed in the interval.

[0011] Preferably, the volume of the main cavity is greater than the volume of the auxiliary cavity.

[0012] Preferably, the cross-sectional area of ​​the upper end of the molten steel container is larger than the cross-sectional area of ​​the lower end.

[0013] Preferably, the auxiliary cavity sidewall with the casting nozzle gradually slopes away from the main cavity from bottom to top.

[0014] The advantages of this utility model are: 1. This utility model utilizes a main baffle to prevent impurities on the molten steel in the main cavity from entering the casting container through the casting nozzle during the early stages of pouring. The main channel at the bottom of the main baffle ensures that impurity-free molten steel at the bottom of the molten steel container can enter the auxiliary cavity, thus ensuring the quality of the molten steel casting. In addition, by setting an auxiliary baffle in the auxiliary cavity, impurities can be prevented from entering the auxiliary cavity during the final pouring process and then entering the casting container through the casting nozzle. Furthermore, by installing a filter plate according to the pouring time, the molten steel can be continuously filtered through the filter plate, ensuring the full utilization of the molten steel, while surface residues are blocked at the filter plate.

[0015] 2. The filter plate of this utility model is installed on the filter plate limiting structure in a detachable manner, which facilitates the removal and cleaning of the filter plate and avoids the impact of filter plate blockage on the pouring of molten steel.

[0016] 3. This utility model can realize the complete pouring of molten steel and completely isolate the residue at the filter screen. This not only ensures the casting quality, but also makes the molten steel more thoroughly utilized compared to traditional molten steel containers, indirectly reducing losses.

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to the accompanying drawings.

[0020] like Figures 1 to 3 As shown, a slag-iron separation device for molten steel casting includes a molten steel container 1. The upper cross-sectional area of ​​the molten steel container 1 is larger than the lower cross-sectional area, similar to a conical structure. A main partition 4 is provided in the molten steel container 1, which divides the molten steel container 1 into a main cavity 2 and an auxiliary cavity 3. The volume of the main cavity 2 is larger than the volume of the auxiliary cavity 3. A main channel 5 is provided between the bottom of the main partition 4 and the bottom of the molten steel container 1, which can connect the main cavity 2 and the auxiliary cavity 3.

[0021] By utilizing the main baffle 4, impurities on the molten steel in the main cavity 2 can be prevented from entering the casting container through the casting nozzle 7 during the early stage of pouring. The main channel 5 at the bottom of the main baffle 4 ensures that the impurity-free molten steel at the bottom of the molten steel container 1 can enter the auxiliary cavity 3, thus ensuring the quality of molten steel casting.

[0022] A casting nozzle 7 is located at the upper end of the auxiliary cavity 3, away from the main cavity 2. The side wall of the auxiliary cavity 3 with the casting nozzle 7 gradually slopes upwards towards the direction away from the main cavity 2. An auxiliary partition 6 is located in the auxiliary cavity 3, close to the casting nozzle 7 and perpendicular to the side wall of the auxiliary cavity 3 away from the main cavity 2. An auxiliary channel 8 is provided between the auxiliary partition 6 and the side wall of the auxiliary cavity 3 away from the main cavity 2. The height of the auxiliary partition 6 is greater than the height of the auxiliary channel 8. The auxiliary channel 8 can connect the chamber near the casting nozzle 7 and the chamber below the auxiliary cavity 3. This structure can prevent impurities from entering the auxiliary cavity 3 during the final pouring process and then entering the casting container through the casting nozzle 7.

[0023] The auxiliary partition 6 is equipped with a filter plate limiting structure, on which a filter plate 9 can be detachably installed. The filter plate 9 can be installed reasonably according to the pouring time, so that the molten steel can be continuously filtered through the filter plate 9, ensuring the full utilization of the molten steel. The surface residue is blocked at the filter plate 9. Moreover, since the filter plate 9 is installed on the filter plate limiting structure in a detachable manner, it is convenient to remove and clean the filter plate 9, avoiding the impact of the filter plate 9 clogging on the pouring of molten steel. Example 1

[0024] The filter plate limiting structure is a boss that extends from the outer edge of the auxiliary cavity 3 to the bottom of the auxiliary cavity 3. The boss has a slot in which the filter plate 9 can be placed. The width of the slot is greater than the thickness of the filter plate 9. The filter plate 9 can cover the auxiliary channel 8. The best time to place the filter plate 9 is when the residue begins to enter the auxiliary cavity 3 or when the residue is about to approach the auxiliary partition 6.

[0025] The auxiliary partition 6 is preferably designed as an arc-shaped plate, with the middle position of the arc-shaped plate recessed towards the casting nozzle 7. The recessed area is more likely to concentrate slag and facilitate the leakage of molten steel on both sides of the arc-shaped plate. Example 2

[0026] In this embodiment, two auxiliary partitions 6 are arranged in parallel, and the filter plate limiting structure is set as the interval between the two auxiliary partitions 6. The filter plate 9 is set in the interval, which can also fulfill the positioning requirements of the filter plate 9.

[0027] It should be understood that these embodiments are for illustrative purposes only and are not intended to limit the scope of protection of this utility model. Furthermore, it should be understood that after reading the technical description of this utility model, those skilled in the art can make various alterations, modifications, and / or variations to this utility model, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
