[0002] The tapping trough plays a crucial role in the blast furnace ironmaking process, primarily separating molten iron from slag. After prolonged slag erosion, the tapping trough needs to be recast. The common method involves uniformly mixing the refractory material and placing it into the tapping trough mold, allowing the material to fill the mold's corners naturally due to its fluidity. Currently, hoisting equipment is typically used to transport the refractory material to different casting locations, which prolongs the tapping trough casting time, resulting in extended blast furnace shutdowns and longer tapping times, significantly impacting blast furnace production stability and output.

[0019] The tank body 10 includes a receiving cavity for containing the castable material and two pouring ports located on both sides of the tank body 10 and communicating with the receiving cavity. The two pouring ports are symmetrically arranged on both sides of the axis of the tank body 10. The tank body 10 can be round or square and can be made of materials such as steel or iron.

[0020] Optionally, the bottom of the tank 10 is conical, which facilitates the flow of the castable and reduces the amount of castable residue in the tank 10.

[0021] The pouring port can be located on the bottom wall of the tank 10 to facilitate the flow of the refractory material within the tank 10 and reduce refractory residue within the tank 10. A guide plate 50 is located at the pouring port and is used to guide the refractory material in the receiving cavity to the tapping trough. The guide plate 50 is rotatably connected to the tank 10 so that the flow direction of the guide plate 50 is adjustable.

[0022] Specifically, a base 53 can be installed outside the pouring opening, and the base 53 consists of two vertical plates. A guide plate 50 is rotatably connected to the tank body 10 via the base 53, allowing the guide plate 50 to be adjusted according to the width of the tapping channel to ensure that the refractory material flows into the pouring channel and avoids waste. Additionally, a flexible hose is connected between the base 53 and the guide plate 50 to prevent refractory material leakage.

[0023] Optionally, the length of the deflector 50 is adjustable, allowing the deflector 50 to be positioned close to the runner, further preventing waste of castable material.

[0024] Specifically, the guide plate 50 includes a base plate 51 and an extension plate 52, the extension plate 52 being slidably connected to the base plate 51 so that the extension plate 52 can slide along the length direction of the base plate 51.

[0025] It should be noted that there are multiple ways to connect the substrate 51 and the extension plate 52. In one embodiment, a screw is provided at the bottom of the substrate 51, and an elongated hole extending along the length of the substrate 51 is provided on the extension plate 52. The screw passes through the elongated hole and is locked with a nut, thereby facilitating the adjustment of the position of the extension plate 52.

[0026] The traveling assembly 40 includes traveling wheels 41, a drive mechanism 42, and a track 43. The traveling wheels 41 are connected to the tank body 10. The number of traveling wheels 41 can be set to four, and they are connected in pairs via connecting shafts. A bracket can be provided between the traveling wheels 41 and the tank body 10, and the connecting shafts are mounted on the bracket. The drive mechanism 42 can be located on the outside or bottom of the tank body 10, or it can be mounted on the bracket. The drive mechanism 42 is used to drive the traveling wheels 41 to rotate. The drive mechanism 42 can be a motor. The track 43 is located on both sides of the iron discharge trough, and the traveling wheels 41 are in a rolling connection with the track 43.

[0027] Optionally, the walking assembly 40 also includes a timing pulley 44, which is connected to the shaft between the walking wheels 41 and is also connected to the output shaft of the drive mechanism 42 to ensure the stability of the transmission between the drive mechanism 42 and the walking wheels 41 and to avoid slippage.

[0028] A cutter 20 is positioned above the tank body 10 and is used to cut the outer packaging of the castable refractory. Specifically, the cutter 20 is located at the center of the top of the tank body 10, and is connected to the upper edge of the tank body 10 via multiple connecting rods 21. The top of the cutter 20 is sharp or blade-shaped. Specifically, there can be three connecting rods 21, the cutter 20 can be conical, and the cutter 20 can be a hollow structure.

[0029] A mixing assembly 30 is disposed inside the tank 10 and is used to mix the castable material inside the tank 10, thereby enabling the castable material to be mixed evenly with water and ensuring the required uniformity during the casting process. Specifically, the mixing assembly 30 includes a mixing shaft, blades, and a drive motor. The mixing shaft is disposed inside the tank 10 and extends longitudinally. The blades are connected to the mixing shaft. The drive motor is disposed outside the tank 10, and the mixing shaft is connected to the drive motor.

[0030] Optionally, the top of the stirring shaft is rotatably connected to the cutter 20 to increase the stability of the stirring shaft, reduce displacement caused by vibration during stirring, and improve stirring efficiency.

[0031] The implementation principle of the blast furnace tapping trough casting device in this application embodiment is as follows:

[0032] During the casting process, the outer packaging of the refractory material is cut open by the cutter 20, allowing the refractory material to enter the tank 10 and mix with the water inside. The drive motor is then started, and the drive motor drives the blades to rotate via the stirring shaft, causing the refractory material and water to mix evenly under the action of the blades. Then, the drive mechanism 42 drives the synchronous wheel 44 to rotate, and the traveling wheel 41 rolls on the track 43 under the action of the synchronous wheel 44, thereby moving the tank 10 on the tapping trough. The refractory material inside the tank 10 enters the sprue between the tapping trough and the mold through the guide plates 50 on both sides, thus completing the casting process. Compared with the prior art, this embodiment of the application eliminates the need to use hoisting equipment to lift the refractory material to different casting points, shortening the casting time of the tapping trough and improving casting efficiency.
