High Quality Calcium Silicon

Professional analysis and technical advantages:1. Metallurgical value of composite reactionsThe core function of calcium:The deoxidation ability (Ca-O) is 1.5 times that of aluminum, and the deoxidation product is low melting point calcium silicate (such as 2CaO · SiO ₂), which is easy to polymerize and float;Deep desulfurization (Ca-S → CaS) suppresses the "thermal brittleness" caused by sulfides;Fixed nitrogen gas (Ca-N → Ca ∝ N ₂) to reduce bubble defects.The synergistic effect of silicon:Assist in deoxygenation and promote calcium recovery (reduce calcium vapor loss);Improve the morphology of deoxygenation products and avoid nozzle blockage caused by Al ₂ O ∝. 2. Innovative improvement of steel performanceInclusion control: Calcium treatment transforms hard Al ₂ O Ⅲ inclusions into spherical calcium aluminate, significantly improving:→ Fatigue strength of steel (+15%~30%);Lateral impact toughness (solving anisotropic problems);Casting optimization: reduce the viscosity of molten s…
