Silicon Calcium Alloy for Deoxidation

Product Advantages

Superior Deoxidation Capacity: The oxygen content in molten steel decreases rapidly. Silicon has a strong affinity for oxygen, quickly combining with free oxygen in the molten steel to form stable SiO₂. Calcium's deoxidation capacity far exceeds that of aluminum and silicon, deeply removing residual oxygen to form low-melting-point oxides, completely solving the problem of excessive oxygen content in molten steel and eliminating defects such as porosity and cracks in the steel.

Simultaneous desulfurization and purification enhance steel toughness: Calcium reacts with sulfur to form stable, insoluble CaS in molten steel, which is rapidly discharged with the slag, achieving deoxidation and desulfurization in one step. This reduces the sulfur content of the steel, improves its plasticity and impact toughness, and meets the production needs of high-end steel and precision castings.

Inclusion modification and optimization prevent continuous casting blockage: High-melting-point Al₂O₃ inclusions in molten steel are converted into low-melting-point calcium aluminates, significantly increasing the flotation rate of inclusions, preventing blockage at the continuous casting nozzle, ensuring a continuous and stable steelmaking process, reducing downtime losses, and improving production efficiency.
