[0038] In addition, in the description of the present application, the terms "first", "second" and the like are only used for distinction and description, and cannot be understood as indicating or implying relative importance.

[0039] As Figures 1-5 shown, the utility model provides a kind of KR desulfurization slag removing plate, comprising:

[0040] The plate body 1 has a material receiving surface 11 and a material backing surface 12, and a plurality of cavities 2 are arranged in the plate body 1, the two ends of the cavities 2 are close to the material receiving surface 11 and the material backing surface 12 respectively, and the cross-sectional area of the cavities 2 gradually increases from the end close to the material receiving surface 11 to the other end.

[0041] In this embodiment, the plate body 1 is the main part of the KR desulfurization slagging plate, and the material receiving surface 11 and the material backing surface 12 clearly define the two main surfaces that the material first contacts and is stressed and the non-first contact and stress. The material receiving surface 11 is used to directly face the material in the KR desulfurization process and bear the impact and friction of the material. The presence of the cavities 2 can fill the slag and part of the molten iron in the cavities 2 after the material receiving surface 11 is worn and the smaller end of the cross-sectional area of the cavities 2 is exposed, which can improve the overall strength and prolong the service life.

[0042] Further, the middle part of the material receiving surface 11 is inwardly recessed.

[0043] In this embodiment, the design of the inwardly recessed middle part of the material receiving surface 11 makes it easier for the material to gather in the recessed part during the KR desulfurization slagging operation. This recessed structure can guide the material flow to a specific area, increase the contact area and contact time of the material with the slagging plate, and thus improve the efficiency of slagging.

[0044] Further, the material receiving surface 11 includes a middle material receiving surface 13 and a side material receiving surface 14, and the left and right sides of the middle material receiving surface 13 are connected with the side material receiving surface 14, and the side material receiving surface 14 on both sides of the middle material receiving surface 13 is inclined to one side.

[0045] In this embodiment, the material receiving surface 11 is further divided into a middle material receiving surface 13 and a side material receiving surface 14, which clearly defines the functional characteristics of different positions on the material receiving surface 11. The middle material receiving surface 13 can generally serve as the main material receiving and slagging operation area, while the side material receiving surfaces 14 on both sides can guide the material flow to the middle material receiving surface 13 during the slagging process, making the material more orderly gathered around the middle material receiving surface 13, facilitating concentrated slagging operation and improving the targeting and efficiency of slagging.

[0046] Further, the connection between the middle material receiving surface 13 and the side material receiving surface 14 has a cavity 2.

[0047] In this embodiment, the connection between the middle material receiving surface 13 and the side material receiving surface 14 is provided with a cavity 2, which can be filled with slag and part of the molten iron after the cavity 2 is exposed, making this part of the structure more firm and prolonging the service life.

[0048] Further, it also includes a wear-resistant reinforcing plate 3, which is arranged on the material receiving surface 11 and close to one side of the material receiving surface 11.

[0049] In the embodiment, the wear-resistant reinforcing plate 3 is arranged on the material receiving surface 11, which can significantly enhance the wear resistance of the material receiving surface 11. In the KR desulfurization slagging process, the material receiving surface 11 directly contacts with the material containing a large amount of impurities and having certain corrosiveness, and is subjected to strong friction and wear. The wear-resistant reinforcing plate 3 can bear most of the friction, effectively protect the base material of the material receiving surface 11, reduce the wear degree, thereby prolonging the service life of the material receiving surface 11 and even the whole slagging plate, and reducing the maintenance cost and replacement frequency of the equipment.

[0050] Further, the plate body 1 is further provided with a connecting plate 4, which is used to connect with the slagging machine.

[0051] In the embodiment, the connecting plate 4 arranged on the plate body 1 establishes a bridge for the connection between the slagging plate and the slagging machine. Through the connecting plate 4, the slagging plate can be firmly installed on the slagging machine, ensuring the cooperative work of the slagging plate and the slagging machine during the slagging operation, so that the slagging machine can accurately drive the slagging plate to perform the slagging action in the KR desulfurization equipment, and realize the functional requirements of the slagging.

[0052] Further, a part of the connecting plate 4 protrudes from the material backing surface 12, and the part of the connecting plate 4 protruding from the material backing surface 12 is rectangular.

[0053] In the embodiment, the part of the connecting plate 4 protruding from the material backing surface and the rectangular protruding part provide a clear positioning reference for the installation of the slagging plate and the slagging machine. During the installation, the operator can accurately align the slagging plate and the slagging machine according to the shape and position of the rectangular protruding part, so that the connection is more convenient and fast, and in addition, the overall strength of the plate body 1 can be improved, and the service life is improved.

[0054] Further, the connecting plate 4 has a connecting portion 41, and the connecting portion 41 is provided with a fixed mounting hole 42 and an angle adjusting hole 43.

[0055] In the embodiment, the fixed mounting hole 42 arranged on the connecting portion 41 is used to firmly install the slagging plate on the slagging machine. By inserting a connecting member such as a bolt into the fixed mounting hole 42, the corresponding parts of the slagging plate and the slagging machine can be tightly connected together, ensuring the position of the slagging plate on the slagging machine fixed, providing a stable basis for the slagging operation, and preventing the slagging plate from shifting or shaking during the work.

[0056] The angle adjustment hole 43 is provided to adjust the installation angle of the slag spitting plate on the slag spitting machine. In different KR desulfurization equipment or slag spitting operation requirements, it may be necessary to adjust the angle of the slag spitting plate to achieve the best slag spitting effect. By using appropriate connecting pieces in the angle adjustment hole and cooperating with the fixed mounting hole 42, the installation angle of the slag spitting plate can be flexibly adjusted to better adapt to different working environments and material conditions, improve the slag spitting efficiency and quality.

[0057] Further, the angle adjustment hole 43 is located on one side of the fixed mounting hole 42, and the angle adjustment hole 43 is an arc-shaped hole with the same center as the angle adjustment hole 43.

[0058] In this embodiment, the angle adjustment hole 43 is designed as an arc-shaped hole, which makes it more convenient and fast to adjust the angle of the slag spitting plate. Compared with other shaped holes, the arc-shaped hole can provide a smoother angle change path during adjustment, and the operator can more easily change the angle of the slag spitting plate by moving the connecting piece in the arc-shaped hole, reducing the resistance and difficulty in the adjustment process and improving the operation convenience of angle adjustment.

[0059] Further, the back material surface 12 also has a strip-shaped reinforcing plate 5, and the strip-shaped reinforcing plate 5 has two, and the two strip-shaped reinforcing plates 5 are cross-shaped.

[0060] In this embodiment, two cross-shaped strip-shaped reinforcing plates 5 are arranged on the back material surface 12, which can significantly enhance the structural strength of the back material surface 12 and improve the overall service life.
