This invention relates to the field of continuous casting technology for steel, and discloses an electromagnetic stirring device and method for the solidification end of continuous casting. The device includes: multiple C-shaped iron cores; a continuously cast billet enters a secondary cooling zone from a crystallizer; the secondary cooling zone has multiple support rollers arranged in an arc shape; the support rollers support and guide the continuously cast billet, causing it to bend on the rollers to form an inner arc side and an outer arc side; the continuously cast billet includes a solid shell and a liquid phase cavity located inside the solid shell; the liquid phase cavity cools and pulls the billet within the secondary cooling zone; the tail end of the liquid phase cavity forms the solidification end; the multiple C-shaped iron cores are spaced apart along the length of the continuously cast billet, with the C-shaped iron cores close to the outer arc side of the billet; coils are wound on the C-shaped iron cores for passing alternating current and generating a linear electromagnetic force along the pulling direction of the liquid phase cavity within the continuously cast billet. This method can promote the movement and accumulation of equiaxed grains towards the solidification end, inhibit the aggregation of solute-rich liquid phase at the center of the continuously cast billet, and thus effectively improve center segregation.

This invention discloses a high-speed data transmission fluoroplastic solid double-insulated core wire with a shell and its manufacturing process. It includes two parallel silver-plated conductors, each covered by a first FEP insulation layer. The two silver-plated conductors covered by the first FEP insulation layer are then covered by a second FEP insulation layer. This invention uses fluoroplastic with a lower dielectric constant as the double-insulation material. Under the same electrical performance requirements, the finished wire diameter is reduced by approximately one-fifth compared to traditional PE insulated core wires, significantly saving space in high-density data center cabinets and improving installation flexibility and heat dissipation. The two primary insulated core wires are tightly integrated with the secondary insulation shell, resulting in a robust overall structure. During bending, twisting, cabling, and subsequent processing, problems such as core wire deformation, structural asymmetry, positional shift, and loose insulation layers are less likely to occur, ensuring stable key electrical parameters such as impedance and return loss.
