The cored wire production line can be understood as a specialized precision rolling equipment for “manufacturing wire.” Through precise cold roll forming technology, it rolls flat steel strip into a round tube and feed the calcium wire into it, ultimately producing a special “metal sausage” – solid calcium cored wire.
In the metallurgical industry, solid calcium cored wire is not the same as everyday electrical wire. It is a ladle refining material used for steelmaking. Simply put, its production process uses a thin layer of steel skin (typically 1.0-1.5mm thick cold-rolled low-carbon steel strip) to tightly wrap calcium wire, finally forming a coil product.
During steelmaking, this solid calcium cored wire is injected deep into molten steel through a wire feeder. After the steel skin melts, the calcium wire reacts directly inside the molten steel, achieving deoxidation, desulfurization, and purification of the liquid steel, thereby greatly improving the yield and quality of high-grade steel products.
