Anyang Hongshun Industrial Co., Ltd.

We specialize in the production and supply of a wide range of products, including ferrosilicon inoculants, silicon-barium inoculants, silicon-calcium inoculants, and silicon-barium-calcium composite inoculants, suitable for ductile iron and gray cast iron production. The key role of inoculants in cast iron production: Inoculants are commonly used in the cast iron production process. By adding them to molten iron, they are uniformly distributed throughout the cast iron, significantly improving its properties. The type and composition of the inoculant require targeted selection depending on the type of cast iron and production requirements. Key Technical Points: Correct inoculant selection has a decisive impact on improving the mechanical properties of cast iron and reducing casting defects. Casting Inoculant Classification: Silicon-Based Inoculants: Main Component: Ferrosilicon (including silicon-calcium, silicon-barium, etc.). Core Function: Promotes graphitization and reduces white cast iron tendency. Improvements: Graphite morphology distribution and the number of eutectic clusters. Carbon-Based Inoculants: Main Component: Carbon. Product Type: Low-carbon/High-carbon Inoculants. Control Focus: Carbon content adjustment. Rare earth inoculants: Active elements include cerium and magnesium. Special functions include grain refinement and performance enhancements such as strength, toughness, and wear resistance. Composite inoculants: Typical formulations include silicon, calcium, barium, and rare earth composites. Comprehensive advantages include synergistic effects from multiple elements. Application scenarios include high-performance cast iron requirements. Core advantages of inoculants include: Stable quality: Uniform particle size, stable composition, high alloy purity, minimal slag inclusions during inoculation, and long anti-decay time. Microstructure optimization: Significantly reduces white cast iron tendency and refines graphite structure. Flexible application: Suitable for both conventional and late-stage instant inoculation of gray and ductile iron. Inoculant application process: Inoculant inoculation: Add inoculant to a ladle, inject molten iron, and then evenly melt and pour, suitable for mass production. Surface inoculation: Evenly spread on the molten iron surface for rapid effect, simple and quick operation. Powder spray inoculation: Dilute proportionally, atomize with a spray gun, and penetrate the mold cavity, allowing for precise dosage control. Inoculant in the pouring cup: Place in the pouring cup → dissolves when the molten iron flows through, improving the shrinkage feeding effect.
