Description

Technical Field

[0001] The utility model relates to the technical field of steel smelting, in particular to scrap steel proportioning weighing equipment. Background Art

[0002] Adding scrap steel to steelmaking can improve the quality of steelmaking. Scrap steel is composed of steel of various materials, qualities, and shapes. Its diversified composition can reduce the excessive or insufficient concentration of certain components in steelmaking, thereby making the composition of steel more uniform and more in line with use requirements. The price of scrap steel is relatively low, and it has a price advantage compared to new steel. Adding scrap steel can reduce the cost of steelmaking. In addition, scrap steel has the characteristics of recycling and reuse, and has obvious environmental advantages. It can save resources and reduce waste disposal, thereby reducing environmental pollution.

[0003] The existing referenceable Chinese utility model patent has a publication number of CN216189211U, which discloses a weighing device for recycling scrap steel, including a base and a fixed frame, wherein the fixed frame is arranged on the base, a mobile grabbing structure is arranged on the fixed frame, a floor scale weighing platform is arranged on the base, and a directional coding structure is arranged on one side of the floor scale weighing platform. The utility model relates to the technical field of recycling scrap steel, a mobile grabbing structure is arranged on the fixed frame, a floor scale weighing platform is arranged below the mobile grabbing structure, and a directional coding structure is arranged on one side of the floor scale weighing platform. The mobile grabbing structure grabs the compressed scrap steel block, places the scrap steel block on the floor scale weighing platform for weighing, and while the weighed weight is uploaded to the data center, the weighing result is directly sprayed on the side wall of the scrap steel block using the directional coding structure. The structure is simple, the degree of automation is high, and it is convenient for later verification and measurement.

[0004] In order to prevent the scrap steel from moving during the weighing process, the existing scrap steel weighing equipment generally uses a frame-type container to hold the scrap steel. This method cannot quickly remove the scrap steel after the scrap steel is weighed. At the same time, during the weighing process, the center of the scrap steel will be offset from the weighing structure, affecting the weighing result. Utility Model Content
