Problems solved by technology

[0007] 1. Raw material preparation adopts general discontinuous casting, which has low production efficiency and low material utilization rate;

[0008] 2. The round rod billet is obtained by hot extrusion process. Due to the uneven deformation of the hot extrusion process, the mechanical properties and metallographic structure of the manufactured profile are poor, and the production process consumes a lot of energy; the surface quality of the round rod billet after hot extrusion Unstable, many defects such as surface inclusions, peeling, extrusion lines, etc., the processing process is complicated and affects product quality

[0009] 3. Continuous production cannot be realized, subsequent wires need to be welded, and the process is complicated
