Technical Field

[0001] The utility model belongs to the technical field of steel processing, and in particular relates to a high-efficiency dephosphorization device for threaded steel. Background Art

[0002] Phosphorus exists in steel in the form of phosphide. Phosphorus in liquid steel makes the steel "cold brittle", so dephosphorization reaction is often used in steelmaking. In order to remove harmful impurities, there are now many dephosphorization methods, among which the most commonly used are pickling, alkali washing, and refining furnace dephosphorization. Among them, refining furnace dephosphorization is a method of dephosphorization during the steelmaking process.

[0003] Chinese utility model patent CN221166609U discloses a highly efficient dephosphorization device for threaded steel, comprising a heat dissipation box, the inner surface of which is provided with a chute, the inner surface of which is slidably connected to a filter frame. By using a fan, a large amount of harmful gases generated during liquid steel processing are discharged, thereby ensuring the stability of the threaded steel dephosphorization operation;

[0004] The above design, through the cooperation of the fan and the heat dissipation holes, can discharge a large amount of gas generated during the processing of liquid steel, preventing harmful gases from accumulating inside the equipment and affecting the quality of the final product. However, there are certain problems during use. Specifically, when the equipment is used, various additives cannot fully react with the phosphorus present in the liquid steel. Some phosphorus flows to the bottom of the liquid steel, and oxygen and dephosphorization agents cannot react with this type of phosphorus, resulting in some phosphorus existing in the liquid steel, affecting the quality of the final rebar.

DETAILED DESCRIPTION

[0025] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0026] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0027] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments. The present invention provides the following embodiments.

[0028] Depend on Figure 1 and Figure 2As shown, it is a structural schematic diagram of the threaded steel efficient dephosphorization device in this embodiment, including a processing furnace 1, a top cover 2 and a bracket 3. The top of the processing furnace 1 is provided with a top cover 2, the outside of the processing furnace 1 is symmetrically fixedly installed with the bracket 3, and the surface of the top cover 2 is fixedly installed with a stirring mechanism 4 for stirring the liquid steel stored in the processing furnace 1.

[0029] During use, the steel to be dephosphorized is heated to a liquid state, and then the liquid steel is input into the processing furnace 1. The top cover 2 is moved to the top opening of the processing furnace 1 by a crane to seal the internal space of the processing furnace 1. At this time, oxygen is input into the processing furnace 1. The phosphorus in the liquid steel will react with the oxygen, thereby preliminarily filtering out the phosphorus in the steel.

[0030] By the attached Figure 3 and Figure 4 As shown, it is a structural schematic diagram of the stirring mechanism 4 in this embodiment, the stirring mechanism 4 includes a driving motor 41, a rotating rod 42, a stirring member 43 and a mixing end 44, the driving motor 41 is fixedly mounted on the upper surface of the top cover 2, the rotating rod 42 is rotatably mounted on the lower surface of the top cover 2, the rotating rod 42 is fixedly connected to the output end of the driving motor 41, the stirring member 43 is fixedly mounted on the outside of the rotating rod 42, and the mixing end 44 is fixedly mounted on the bottom end of the rotating rod 42.

[0031] During use, the driving motor 41 drives the output end of the driving motor 41 to drive the rotating rod 42 to rotate, so that the stirring member 43 stirs the liquid steel inside the processing furnace 1, so that the oxygen and the phosphorus in the liquid steel fully react, and the use of the mixing end 44 stirs the bottom part of the liquid steel, so that the liquid steel is fully stirred inside the processing furnace 1 and fully reacts with the oxygen.

[0032] By the attached Figure 4 As shown, the stirring mechanism 4 also includes a toggle rod 45, which is fixedly installed on the outside of the rotating rod 42, and the toggle rod 45 is arranged above the stirring member 43. During use, the toggle rod 45 is used to move along the liquid steel level to push the impurities accumulated on the surface of the material, so that oxygen can better react with the phosphorus in the material.

[0033] By the attached Figure 5 As shown, it is a structural schematic diagram of the gas delivery mechanism 5 in this embodiment. The threaded steel high-efficiency dephosphorization device also includes a gas delivery mechanism 5, which includes a connecting seat 51, a gas delivery pipe 52 and a first control valve 53. The connecting seat 51 is fixedly mounted on one side of the upper surface of the top cover 2, and the gas delivery pipe 52 is connected to the connecting seat 51. The first control valve 53 is arranged on the outside of the gas delivery pipe 52. During use, oxygen is passed through the gas delivery pipe 52 and the pump body, and is input into the interior of the processing furnace 1 through the top cover 2. The stirring mechanism 4 is used to allow the oxygen to fully react with the phosphorus in the liquid steel, and the phosphorus in the liquid steel is removed.

[0034] By the attached Figure 5 As shown, it is a structural diagram of the gas delivery mechanism 5 in this embodiment. The gas delivery pipe 52 transports oxygen for reacting with phosphorus in liquid steel. Oxygen reacts with phosphorus to generate phosphorus oxide. During use, oxygen is input into the processing furnace 1, and oxygen reacts with phosphorus to generate phosphorus oxide, thereby achieving preliminary filtration of phosphorus.

[0035] By the attached Figure 6 As shown, it is a structural schematic diagram of the feeding mechanism 6 in this embodiment. The threaded steel efficient dephosphorization device also includes a feeding mechanism 6, which includes a feeding pipe 61, a connecting seat 62 and a second control valve 63. The connecting seat 62 is fixedly installed on the upper surface of the top cover 2, and the feeding pipe 61 is connected to the connecting seat 62. The second control valve 63 is arranged on the outside of the feeding pipe 61. In use, after the initial extraction of phosphorus is completed, the dephosphorization agent to be used is input into the processing furnace 1 through the cooperation and transportation of the feeding pipe 61. At this time, the dephosphorization agent reacts with phosphorus oxide to generate a phosphorus oxide complex that is insoluble in molten steel, thereby removing phosphorus from the steel. Subsequently, when the liquid steel inside the processing furnace 1 is discharged, the phosphorus screening can be completed by filtering.

[0036] By the attached Figure 5 As shown, a lifting frame is symmetrically installed on the surface of the top cover 2, and a harmful gas extraction port is installed on one side of the surface of the top cover 2. During use, the installation of the lifting frame facilitates the lifting and movement of the top cover 2 and the positions of the components on the surface of the top cover 2. The opening of the gas extraction port facilitates the extraction of various harmful gases existing inside the processing furnace 1 after the phosphorus oxide complex is generated, which is convenient for subsequent centralized treatment.

It cannot be determined that the specific implementation of the present invention is limited to these descriptions.
