Lime Stone(Calcium Carbonate)

• Enhanced Slag Fluidity: It reacts rapidly with silica ($SiO_2$) from coke ash and oxidized sand to form a liquid slag, ensuring smooth tapping and clean separation from the molten iron.

• Optimized Airflow (Permeability): Our limestone is crushed and screened to uniform lump sizes (e.g., 30–70mm). This consistent sizing is critical for maintaining proper air permeability and gas flow within the cupola burden.

• Lining Protection: By neutralizing acidic components in the melt, it helps minimize chemical attack on the furnace’s refractory lining, significantly extending the life of the refractory.

• High Chemical Purity: With a high $CaO$ yield and minimal sulfur/phosphorus content, it helps maintain the chemical integrity of the base iron.

Applications:

• Primary fluxing agent for Gray Iron and Ductile Iron production in cupola melting shops.

• Ideal for continuous melting processes where consistent slag chemistry is required
