[0024] In a preferred embodiment, the top end of the No. 1 pipe 5 passes through the outer wall of the cylinder 1, and the outer wall of the No. 1 pipe 5 is fixedly connected to the No. 1 one-way valve 10. When the argon gas enters the interior of the No. 1 pipe 5, the argon gas can pass through the No. 1 one-way valve 10 inside the No. 1 pipe 5, so that the argon gas can enter the interior of the ventilation groove 4.
[0025] In a preferred embodiment, a No. 2 one-way valve 11 is fixedly connected to the outer wall of the No. 2 pipeline 6, and a movable plate 12 is fixedly connected to the end of the extrusion rod 9 away from the extrusion plate 8. When argon enters the interior of the No. 2 pipeline 6, the argon can pass through the No. 2 one-way valve 11 inside the No. 2 pipeline 6, so that the argon can enter the liquid storage tank 3.

[0027] Working principle of the utility model: when using the device, it is necessary to first pass the molten steel into the liquid storage tank 3, at this time, connect the No. 1 pipeline 5 with the container filled with argon gas, and put the calcium sulfide powder into the bottle body 20, start the motor 17, the output shaft of the motor 17 drives the driving shaft 16 to move, so that the driving shaft 16 rotates inside the groove 7, and the driving shaft 16 drives the rotating plate 15 to move, so that the rotating plate 15 moves in a circular motion inside the groove 7, and the rotating plate 15 drives the slider 14 to move at the same time, so that the slider 14 moves in a circular motion inside the groove 7, and the slider 14 slides in the chute 13 at the same time, so that the rotating plate 15 drives the movable plate 12 to move through the slider 14 and the chute 13 at the same time, so that the movable plate 12 slides in the groove 7, and the movable plate 12 drives the extrusion rod 9 to move at the same time, so that the extrusion rod 9 slides in the groove 7, and the extrusion rod 9 slides in the ventilation groove 4 at the same time, and the extrusion rod 9 drives the extrusion plate 8 to move at the same time, so that the extrusion plate 8 is in the ventilation groove 4 When the extrusion plate 8 moves toward the groove 7, the argon gas will enter the ventilation groove 4 from the No. 1 pipe 5 through the No. 1 one-way valve 10. When the extrusion plate 8 moves in the opposite direction of the groove 7, the extrusion plate 8 can squeeze the argon gas inside the ventilation groove 4, so that the argon gas can enter the No. 2 pipe 6 from the ventilation groove 4, and pass through the No. 2 one-way valve 11 inside the No. 2 pipe 6.

At this time, the calcium sulfide powder will flow into the surface of the molten steel, and the argon gas will blow the molten steel on the edge of the liquid tank 3. Because the liquid tank 3 is circular, the calcium sulfide powder can flow slowly on the surface of the molten steel, causing the calcium sulfide powder to react with the molten steel faster, thereby accelerating the subsequent reaction of the molten steel with the calcium sulfide powder, thereby reducing the energy consumption of the subsequent equipment.
