Description

Technical Field

[0001] The utility model relates to the technical field of continuous casting and rolling copper rod production, in particular to a soot nozzle structure for a copper ring mold of a casting wheel. Background Art

[0002] Currently, during the production process of a continuous casting and rolling copper rod production line, two spray guns are often used for soot spraying on the copper ring mold of the casting wheel. One spray gun sprays soot on the bottom of the concave copper ring mold by burning acetylene, and the other spray gun sprays soot on the side of the concave copper ring mold by burning acetylene. The thickness and uniformity of the soot sprayed on the surface of the copper ring mold of the casting wheel directly affect the crystal structure of the cast billet, thereby affecting the quality of the copper rod product. Since there are three surfaces of the concave mold of the copper ring of the casting wheel that need to be sprayed with soot, two spray guns are usually used. One spray gun for spraying the bottom surface is called the main spraying, and one spray gun with two rows of nozzles with 90° combustion holes for spraying the two side surfaces is called the side spraying.

[0003] However, because the main spraying soot on the bottom surface of the copper ring mold of the casting wheel will spread to the side surface, when a uniform layer of soot is covered on the side surface by side spraying, and when the main spraying soot spreads to the side surface again, the soot layer on the lower side of the side surface of the copper ring mold of the casting wheel near the bottom surface will be thicker than the soot layer on the upper side near the top surface. As a result, the thickness of the soot layer on the side surface of the mold is inconsistent up and down. The thickness and uniformity of the soot layer directly affect the cooling intensity of the cast billet. The uneven thickness of the soot will cause the uneven cooling crystal structure of the cast billet, seriously affecting the crystal structure of the cast billet, and even causing cracks on the side surface of the cast billet, ultimately affecting the quality of the copper rod product.

[0004] Therefore, we propose a soot nozzle structure for a copper ring mold of a casting wheel to overcome the above problems. Summary of the Utility Model

[0005] Aiming at the above deficiencies existing in the prior art, the purpose of the utility model is to provide a soot nozzle structure for a copper ring mold of a casting wheel, which is used to solve the problem that in the existing continuous casting and rolling copper rod production line, the side surface of the copper ring mold of the casting wheel is sprayed with soot by using an equal-diameter and equal-spacing row hole nozzle to burn acetylene. Since the main spraying soot on the bottom surface of the copper ring mold of the casting wheel will spread to the side surface, after a uniform soot layer is sprayed on the side surface of the copper ring mold of the casting wheel by the side nozzle, when the main spraying soot spreads to the side surface of the mold again, it will cause the problem of uneven thickness of the soot layer on the side surface.

[0006] The technical solution adopted by the present utility model to achieve the above object is as follows: A soot nozzle structure for a casting wheel copper ring mold, including a nozzle structure, and the nozzle structure is provided on the lateral surface of the radial direction of a casting wheel copper ring mold. The nozzle structure includes a fine-threaded hole, a first nozzle combustion hole group, and a second nozzle combustion hole group. The fine-threaded hole is opened on the end surface of the nozzle structure along its length direction. The first nozzle combustion hole group is opened on the side surface of the nozzle structure along its thickness direction. The second nozzle combustion hole group is opened on the side surface of the nozzle structure along its width direction.

[0007] In order to further improve the usability of the soot nozzle structure for a casting wheel copper ring mold, the solution adopted by the present utility model is: The first nozzle combustion hole group includes several first nozzle combustion holes for ejecting carbon black.

[0008] In order to further improve the usability of the soot nozzle structure for a casting wheel copper ring mold, the solution adopted by the present utility model is: Each of the first nozzle combustion holes has an equal diameter spacing from bottom to top.

[0015] Advantages of the present utility model: The soot nozzle structure of the casting wheel copper ring mold realizes a gradient distribution of the thickness of the combustion soot layer through the gradient arrangement of two groups of nozzle combustion holes. When the nozzle structure extends to the side, soot with a thinner upper part and a thicker lower part is formed for secondary coverage, so as to ensure that the thickness of the soot layer on the side of the casting wheel copper ring mold is always uniform, thereby ensuring that during the continuous casting process of the billet, the side is evenly cooled to form a good crystal structure, effectively improving the quality of the copper rod products in the continuous casting and rolling copper rod production line.

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present utility model.

[0026] Please refer to Figures 1 to 5 , a soot nozzle structure of a casting wheel copper ring mold of the present utility model, includes a nozzle structure 2, and the nozzle structure 2 is arranged on the side surface of the radial part of a casting wheel copper ring mold 1.

[0027] Please refer to Figures 6 to 8 , the nozzle structure 2 includes a fine-threaded screw hole 21, a first nozzle combustion hole group 22 and a second nozzle combustion hole group 23. The fine-threaded screw hole 21 is opened on the end face of the nozzle structure 2 along its length direction. The first nozzle combustion hole group 22 is opened on the side face of the nozzle structure 2 along its thickness direction. The second nozzle combustion hole group 23 is opened on the side face of the nozzle structure 2 along its width direction. The nozzle structure 2 is connected to the relevant spraying bracket (such as: triangular bracket, steel plate bracket) through the fine-threaded screw hole 1, and acetylene burns through the first nozzle combustion hole group 22 and the second nozzle combustion hole group 23 to generate soot and spray it onto the side face of the copper ring mold 1 of the casting wheel to form a soot layer.

[0028] The first nozzle combustion hole group 22 includes several first nozzle combustion holes for ejecting carbon black. Each of the first nozzle combustion holes has an equal diameter spacing from bottom to top, and the first nozzle combustion holes are arranged in a one-word gradient distribution from large to small. Each of the first nozzle combustion holes forms a carbon black ejection trajectory 3 during the combustion operation. Since the first nozzle combustion holes are designed with a gradient distribution of equal diameter spacing from bottom to top and from large to small, the side nozzle structure 2 forms a soot layer with a thicker upper part and a thinner lower part when spraying on the side face of the copper ring mold 1 of the casting wheel. When the nozzle structure 2 sprays the bottom surface, it extends to the side face to form a soot layer with a thinner upper part and a thicker lower part. The two are superimposed on each other to form a soot layer with a uniform thickness on the side face of the copper ring mold 1 of the casting wheel, ensuring uniform cooling of the side face of the casting blank and improving the internal quality of the casting blank.

[0029] The second nozzle combustion hole group 23 includes several second nozzle combustion holes for ejecting carbon black. Each of the second nozzle combustion holes has an equal diameter spacing from bottom to top, and the second nozzle combustion holes are arranged in a one-word gradient distribution from large to small. Each of the second nozzle combustion holes forms a carbon black ejection trajectory 3 during the combustion operation. Since the second nozzle combustion holes are designed with a gradient distribution of equal diameter spacing from bottom to top and from large to small, the side nozzle structure 2 forms a soot layer with a thicker upper part and a thinner lower part when spraying on the side face of the copper ring mold 1 of the casting wheel. When the nozzle structure 2 sprays the bottom surface, it extends to the side face to form a soot layer with a thinner upper part and a thicker lower part. The two are superimposed on each other to form a soot layer with a uniform thickness on the side face of the copper ring mold 1 of the casting wheel, ensuring uniform cooling of the side face of the casting blank and improving the internal quality of the casting blank.
