1. Deoxidation: CaFe cored wire is used for deoxidizing molten steel. Calcium has a strong affinity for oxygen, and by introducing CaFe cored wire into the steel bath, it reacts with oxygen and forms calcium oxide (CaO). This helps reduce the oxygen content in the steel, preventing the formation of undesirable oxides.
2. Desulfurization: Calcium is effective in reducing sulfur content in steel. CaFe cored wire facilitates desulfurization by reacting with sulfur in the molten steel to form calcium sulfide (CaS), which can be easily removed.
3. Inclusion Modification: : Adding calcium through CaFe cored wire helps modify the size, shape, and composition of non-metallic inclusions in steel. This contributes to the improvement of steel cleanliness and mechanical properties.
4. Alloying: CaFe cored wire is sometimes used as an alloying agent, contributing to the enhancement of specific properties in steel. It can adjust the calcium and iron content in the steel to achieve specific metallurgical requirements.
5. Control of Residual Elements: The use of CaFe cored wire allows for better control over residual elements in steel. It assists in reducing or controlling the levels of elements such as oxygen, sulfur, and other impurities.
2. Improve Fluidity and Castability: The addition of calcium enhances the fluidity of molten steel, making it easier to cast into desired shapes. This is particularly important in processes like continuous casting.
2. Microalloying: 7. Microalloying: CaFe cored wire can be part of microalloying strategies to achieve specific microstructural characteristics in the steel, leading to improved strength and toughness
In summary, CaFe cored wire plays a crucial role in refining steel properties and ensuring high-quality steel production.
