Based on the embodiments in the utility model, all other embodiments obtained by the person skilled in the art without making creative labor belong to the range of protection of the utility model.

[0021] Please refer to Figures 1-4As shown, a double-layer magnesium core nodulizer cored wire includes a double-layer sleeve 1, which is designed to provide additional structural strength and heat resistance. The inside of the double-layer sleeve 1 is uniformly designed with reinforced connecting rods 2 to increase the connecting strength between the double-layer sleeve 1, prevent deformation or rupture of the sleeve in high-temperature or high-pressure environments, and improve the filling effect of the alloy powder 5. A solid spring 3 is installed at the center of the double-layer sleeve 1 for heat conduction, which ensures that the magnesium metal material 4 can be uniformly heated and improves the overall filling effect of the magnesium metal material 4. The center of the double-layer sleeve 1 is filled with a magnesium metal material 4 to promote the formation and spheroidization of graphite during casting. The outside of the double-layer sleeve 1 is filled with an alloy powder 5 to further increase the performance of the nodulizer. The outside of the double-layer sleeve 1 is equipped with a heat insulation sleeve 6 to reduce heat transfer to the external environment. The outside of the heat insulation sleeve 6 is designed with a broken skin structure 7 to easily tear or cut the cored wire when needed for easy use.

[0022] The reinforced connecting rods 2 include transverse connecting rods and longitudinal connecting rods. The transverse connecting rods are uniformly distributed horizontally in the inside of the double-layer sleeve 1, and the longitudinal connecting rods are uniformly distributed vertically in the inside of the double-layer sleeve 1. The transverse connecting rods and the longitudinal connecting rods are staggered with each other. The reinforced connecting rods 2 are integrally formed with the double-layer sleeve 1. This design forms a grid-like structure, enhancing the overall strength and stability of the double-layer sleeve 1 and making the surrounding alloy powder 5 filling more secure.

[0023] The solid spring 3 is located at the center of the double-layer sleeve 1 and inside the magnesium metal material 4. The solid spring 3 is tightly connected with the magnesium metal material 4. As a heat conduction medium, the solid spring 3 can effectively transfer heat from the outside of the double-layer sleeve 1 to the inside of the magnesium metal material 4, ensuring that the magnesium metal material 4 can be uniformly heated and undergo the expected chemical reaction. The solid spring 3 plays a supporting role inside the magnesium metal material 4, helping to prevent the magnesium metal material 4 from collapsing or deforming at high temperatures. The position and connection method of the solid spring 3 in the double-layer magnesium core nodulizer cored wire are designed very cleverly, which not only ensures effective heat conduction but also provides necessary support, providing a strong guarantee for the efficient use of the nodulizer.

[0024] The heat insulation sleeve 6 is connected with the double-layer sleeve 1 in a damping manner. Split guide grooves are provided on both sides of the heat insulation sleeve 6, and annular division grooves are uniformly provided on the outside of the heat insulation sleeve 6. The main function of the heat insulation sleeve 6 is to reduce the transfer of heat from the double-layer sleeve 1 to the external environment, thereby protecting the surrounding equipment and operators from high temperatures. By reducing heat transfer, the heat insulation sleeve 6 also helps to protect the double-layer sleeve 1 and the magnesium metal material 4 inside from excessive heat damage, prolonging their service life. The design of the split guide grooves and the annular division grooves makes the heat insulation sleeve 6 adaptable to different application scenarios and operation requirements, improving its versatility and practicality.

[0025] The skin breaking structure 7 comprises a positioning sleeve 701, both sides of the positioning sleeve 701 are designed with cutting operation pipes 702, the inside of the cutting operation pipes 702 is connected with a push-pull cutting plate 703. One end of the push-pull cutting plate 703 is fixedly installed with a triangular cutting knife 704, the triangular cutting knife 704 is corresponding to the position of the split guide groove, through the triangular cutting knife 704 on the push-pull cutting plate 703, the user can cut along the split guide groove on the heat insulation sleeve 6, so as to conveniently tear or divide the heat insulation sleeve 6. The inside of the cutting operation pipe 702 is fixedly welded with a rotating installation shaft, the outside of the rotating installation shaft is sleeved with a supporting connecting block, the push-pull cutting plate 703 and the supporting connecting block are fixedly connected with each other. One end of the supporting connecting block is provided with a rotating installation hole, the outside of the rotating installation shaft is sleeved with a return spring 705, the rotating installation hole is sleeved on the outside of the return spring 705, one end of the return spring 705 and the rotating installation shaft are fixedly connected with each other, the other end of the return spring 705 and the supporting connecting block are fixedly connected with each other. The existence of the return spring 705 makes the push-pull cutting plate 703 automatically reset after cutting, which is convenient for the next cutting operation. The design of the skin breaking structure 7 makes the user easily tear or divide the heat insulation sleeve 6 according to the need, without causing damage to the double-layer sleeve 1 and the magnesium material 4 inside. The design of the skin breaking structure 7 fully considers the practicability, safety and ease of use. Through the ingenious mechanical design and material selection, it provides a high-efficiency and reliable cutting tool for the user, so that the use and maintenance of the double-layer magnesium core spheroidizing agent cored wire becomes more simple and convenient.
