INTRODUCTION
The particle size is moderate, the porosity is large, and the absorption rate is fast. The chemical composition is pure, high carbon, low sulfur and harmful ingredients are extremely small, and the absorption rate is high. The graphite crystal structure of the product is good, and the nucleation ability of the molten iron is improved. The number of graphite balls in nodular cast iron is increased during inoculation, and the graphite crystal nucleus is increased in molten iron of electric furnace. Fine and uniform distribution of fossil ink in castings, excellent and stable performance.
