Silicon calcium barium Fesi45Ca13Ba10

Against the backdrop of pursuing ultimate cost reduction and quality upgrading in the steel industry, Si Ca Ba alloy has evolved from a "candidate material" to a key carrier for process optimization. This article aims to systematically explain the technical principles, empirical data, and full value chain benefits that surpass traditional deoxidizers (pure aluminum, silicon calcium alloys).Technological bottleneck and innovation breakthrough: the "stabilizer" effect of bariumAfter traditional silicon calcium alloys are added to molten steel, a large amount of calcium evaporates and oxidizes due to high vapor pressure, and the actual utilization rate is often lower than expected. The core technological breakthrough of this product lies in the introduction of the element "barium".Mechanism of action: Barium significantly reduces the vapor pressure of calcium in molten steel and increases its solubility.Visual comparison: To achieve the same effective calcium content, the amount of silico…
