Embodiment 1

[0028] The cross-sectional structure of a metal smelting device driven by gravity potential energy is as follows figure 1 As shown, the injection tank 1 is a groove structure with 6 injection holes evenly arranged at the bottom; the bottom of the injection tank 1 is connected to the flow regulating plate 2, the flow regulating plate 2 is a flat plate, and the flow regulating plate is evenly provided with 6 Each flow adjustment hole has the same shape as the injection hole. When one injection hole coincides with one flow adjustment hole, other injection holes also coincide with one injection hole. Adjusting the horizontal position of the flow adjustment plate 2 can make the injection hole and the flow adjustment hole be completely connected, partially connected or completely disconnected; when the injection hole is partially connected with the flow adjustment hole, each injection hole is connected to the corresponding flow adjustment hole The connected areas are equal.

Embodiment 2

[0039] The adopted metal smelting device driven by gravitational potential energy is the same as that of Embodiment 1, with the difference that: the top view of the deflector is a curved line type. The sectional structure of the funnel-shaped swirl generator is as follows Figure 4 As shown, the top view structure is as Figure 5 Shown.

[0040] The above-mentioned device is used for dephosphorization, desulfurization and desiliconization tests, and the working method is the same as that of Example 1. The content of phosphorus, sulfur and silicon in the molten steel reaches the expected index, and the effect is better than the smelting effect of argon injection and stirring.

Embodiment 3

[0042] The adopted metal smelting device driven by gravitational potential energy is the same as that in Example 1. The difference lies in: the deflector is a straight plate, the lower end of the lower edge of the outer side of each deflector is connected to the top of the mixing pipe, and the diameter of the deflector is The diameter is the same as the mixing tube; the lower edge of the outer side of each deflector is tangent to the deflector surface. The sectional structure of the funnel-shaped swirl generator is as follows Figure 6 As shown, the top view structure is as Figure 7 Shown.

[0043] The above-mentioned device is used for dephosphorization, desulfurization and desiliconization tests, and the working method is the same as that of Example 1. The content of phosphorus, sulfur and silicon in the molten steel reaches the expected index, and the effect is better than the smelting effect of argon injection and stirring.

Abstract

The invention relates to a metal smelting device driven by gravitational potential energy and a method thereof, relating to the field of metallurgical technology. The device comprises a teeming device, a funnel-shaped cyclone generator and an overflow trough; the upper side of the overflow trough is provided with the funnel-shaped cyclone generator on which the teeming device is arranged; the funnel-shaped cyclone generator consists of a cone-shaped body, a hybrid tube and a guide plate; and the cone-shaped inner side of the cone-shaped body is connected guide plates, and the hybrid tube of the funnel-shaped cyclone generator is inserted into the overflow trough. The application method comprises the following steps: under the action of gravity, molten metal is poured between the guide plates of the funnel-shaped cyclone generator, and then the molten metal flows to the hybrid tube along the guide plate and enters the overflow trough. The device is simple in structure and convenient in operation, thereby achieving the purposes of saving energy and reducing cost.

Description

Technical field [0001] The invention belongs to the technical field of metallurgy, and particularly relates to a metal smelting device and method driven by gravitational potential energy. Background technique [0002] The development of modern industry not only requires metallurgical enterprises to produce high-quality, high-performance products, but also in order to protect the earth's environment and achieve sustainable development, the production process of products must also be efficient, low-cost, and resource-saving. The process principle of the metallurgical reactor is to achieve the mixing of molten steel and the required components (alloying elements and smelting powder) and the separation of harmful components (non-metallic inclusions) through the method of stirring (mechanical stirring, air jet stirring, electromagnetic stirring) the goal of. A good metallurgical reactor should have the dual capabilities of high-efficiency mixing and high-efficiency separation. [0003...
