Detailed Implementation

[0021] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0022] The following describes an embodiment of the present invention with reference to the accompanying drawings: a pouring basin for spheroidizing molten iron.

[0023] like Figures 1-5 As shown, the pouring basin for spheroidizing molten iron in this embodiment of the present invention may include: basin body 1 and stopper rod 5.

[0024] The basin 1 is provided with a spheroidizing chamber 2 and a pouring chamber 3, and a second connecting hole 4 is provided between the spheroidizing chamber 2 and the pouring chamber 3.

[0025] It should be noted that the height of the spheroidizing chamber 2 described in this embodiment is greater than that of the casting chamber 3, which allows most of the molten iron after spheroidizing treatment to enter the interior of the casting chamber 3 first.

[0026] The bottom wall of the spheroidizing chamber 2 is provided with a spheroidizing agent pit 21.

[0027] The bottom wall of the casting chamber 3 has a first connecting hole 31, and the bottom wall of the casting chamber 3 has a round steel plate 32, which is placed at the first connecting hole 31.

[0028] It is understandable that setting a round steel sheet 32 ​​at the first connecting hole 31 can prevent turbulence and air entrapment when molten iron passes through the first connecting hole 31, thereby ensuring the quality of the casting.

[0029] The plug rod 5 is connected to the outer wall of the basin 1, and extends into the interior of the spheroidizing chamber 2. The plug rod 5 is attached to one side of the second connecting hole 4.

[0030] Specifically, first, the plug rod 5 is placed at the second connecting hole 4 between the spheroidizing chamber 2 and the casting chamber 3. Then, the spheroidizing agent, inoculant, and covering agent are placed in the spheroidizing agent pit 21 in sequence. The entire basin 1 is placed on the mold with the help of an external lifting device. Then, the round steel plate 32 is installed, and the first connecting hole 31 is connected with the sprue on the mold.

[0031] The molten iron meeting the temperature control requirement is poured from the electric furnace into the ladle, and then the molten iron in the ladle is poured into the spheroidizing chamber 2, and the molten iron is spheroidized in the pouring basin, and after the spheroidizing, the molten iron is filled into the pouring chamber 3 after the opening of the taphole rod 5, and the high-temperature molten iron melts the round steel sheet 32, and the molten iron enters the sprue on the casting mold through the first communication hole 31.

[0032] In the pouring process, the related personnel do not need to remove the spheroidizing slag, labor and molten iron are saved, and the ladle does not need to be frequently maintained.

[0033] The liquid level of the molten iron in the spheroidizing chamber 2 and the pouring chamber 3 is lowered, and the spheroidizing slag is left in the spheroidizing chamber 2, and after the pouring is completed, the basin body 1 can be placed away from the sand box by means of the external lifting tool, and the related personnel can process the spheroidizing slag in the spheroidizing chamber 2.

[0034] In an embodiment of the present application, as shown in Figure 1 , the basin body 1 comprises a frame body 11 and a refractory brick layer 12.

[0035] Among them, the refractory brick layer 12 is arranged inside the frame body 11.

[0036] In an embodiment of the present application, as shown in Figure 1 , Figure 3 and Figure 4 , the taphole rod 5 comprises a fixed frame 51, a support rod 52, a rocker 53, a steel column 54 and a plurality of first refractory bricks 55.

[0037] Among them, the fixed frame 51 is arranged on the outer wall of the frame body 11, one end of the support rod 52 is arranged inside the fixed frame 51, the rocker 53 is hinged with the support rod 52, one end of the steel column 54 is hinged with the rocker 53, and the plurality of first refractory bricks 55 are arranged on the steel column 54. One first refractory brick 55 is attached to one side of the second communication hole 4.

[0038] It should be noted that the distance between one end of the rocker 53 and the hinged position of the rocker 53 and the support rod 52 in this embodiment is greater than the distance between the hinged position of the rocker 53 and the support rod 52 and the other end of the rocker 53, so that when the rocker 53 is driven, the plurality of first refractory bricks 55 can be lifted based on the principle of leverage.

[0039] Specifically, when the taphole rod 5 opens the second communication hole 4, the related personnel press one end of the rocker 53, and the rocker 53 rotates around one end of the support rod 52, so that the plurality of first refractory bricks 55 are lifted, the second communication hole 4 is opened, and the molten iron enters the inside of the pouring chamber 3.

[0040] In an embodiment of the present application, as shown in Figure 5 , two lifting lugs 61 are arranged on the basin body 1.

[0041] It can be understood that the lug 61 is arranged to facilitate the transfer of the pouring basin by using external lifting devices.

[0042] In conclusion, the pouring basin for spheroidizing molten iron integrates the spheroidizing chamber and the pouring chamber, and transfers the spheroidizing process of the molten iron to the sand box, so that the slag after spheroidizing is not needed to be removed, labor and molten iron are saved, and the ladle does not need to be frequently maintained.
