In the field of calcium treatment for steel refining, an innovative product that combines materials science and metallurgical principles - solid silicon calcium wire - is attracting industry attention. This product breaks through the traditional design concept of powder coated core wire, using steel strip to directly wrap solid calcium wire and a specific proportion of silicon iron powder, and forming them together through edge rolling and interlocking technology, providing a new solution for optimizing the composition control of molten steel.
In traditional processes, unstable calcium yield and impurity introduction are common challenges. The core innovation of solid silicon calcium wire lies in its unique "calcium silicon" composite core structure. The addition of silicon iron powder is not simply mixing, but plays a key physical and chemical synergistic role: on the one hand, its melting process can locally adjust the temperature of the molten steel, creating better reaction conditions; On the other hand, silicon can significantly increase the solubility of calcium in molten steel, thereby ensuring the efficient and stable absorption of calcium. This design enhances the penetration of calcium wire during feeding, significantly improves the yield of calcium, and effectively reduces the risk of nitrogen addition in molten steel.
