Four-layer structure of seamless calcium wire welding
The seamless pure calcium wire includes an outer layer and an inner layer. The outer layer is overlapped and welded. The overlap is in an inwardly folded shape. The overlap is composed of four layers of the outer layer, wherein , from the outside to the inside, they are the first layer, the second layer, the third layer and the fourth layer respectively, and the first layer and the second layer are welded and connected. In addition to the advantages of the existing seamless pure calcium wire, the present invention should reduce the production cost. In addition, the wire feeding machine can use the existing single-layer pure calcium wire feeding machine, which is relatively easy to promote and is helpful for solving the current domestic problem of single-layer double-layered calcium wire. It is of great significance to reduce the smelting cost due to the splashing and nitrogen increase caused by the pure calcium wire.
