Silicon calcium barium Fesi45Ca7Ba15

Silicon calcium barium alloy, as an innovative composite deoxidizer in modern steelmaking production, is gradually replacing traditional single deoxidizing materials (such as ordinary ferrosilicon, pure aluminum, etc.) with its excellent comprehensive metallurgical properties, becoming a key technical means to optimize steel cleanliness, improve steel quality, and reduce production costs. Its core value lies in the synergistic effect of multiple elements to achieve efficient deoxidation, deep purification, and control of non-metallic inclusion morphology, especially suitable for continuous casting processes that require strict purity of molten steel.Strong deoxidation and inclusion denaturation:Silicon (Si), as the basic deoxidation element, first reacts with free oxygen in the molten steel to achieve preliminary deoxidation.The deoxidation ability of calcium (Ca) and barium (Ba) far exceeds that of silicon and aluminum. They can further undergo deep deoxidation and combine with deoxid…
