Silicon Calcium 30-60mm For Ladle Treatment

Calcium Silicon is a calcium-silicon alloy made mainly from calcium and silicon, with controlled levels of carbon, sulfur, phosphorus and aluminum. In steelmaking, calcium and silicon work together as active alloying elements. Silicon supports deoxidation, while calcium helps modify inclusions and improve molten steel treatment performance.

The 30–60mm lump size is suitable for ladle treatment because it is easier to weigh, handle and add during steelmaking operation. Compared with excessive fine material, lump calcium silicon can reduce dust loss during storage and feeding. Compared with oversized lumps, 30–60mm material is more practical for regular furnace and ladle addition.

You can use Calcium Silicon 30–60mm when your steelmaking process needs deoxidation support, sulfur control and inclusion modification in the ladle stage. Before order, we help you confirm whether the Ca / Si grade, lump size and impurity limits match your treatment method and steel quality requirement.

Ladle Treatment

30–60mm calcium silicon alloy serves as essential refining additive for post-smelting ladle processing. After initial melting, it is added into molten steel to carry out deep deoxidation and effective desulfurization. It stabilizes molten steel composition, eliminates harmful impurities and optimizes molten steel state, laying solid foundation for high-quality casting forming.

Inclusion Modification

Calcium element contained in the alloy reacts with oxide and sulfide inclusions inside molten steel. It transforms irregular hard inclusions into fine, dispersed harmless substances. This remarkably improves internal cleanliness of finished steel, reduces material defects and enhances overall mechanical performance of steel products.

Steel Refining Support

Lump-shaped calcium silicon with 30–60mm particle size features stable dissolution speed, perfectly matching conventional ladle feeding and refining techniques. It realizes steady element release and uniform component distribution. We can supply products with customized particle size and calcium-silicon ratio, fully adapting to diverse ladle processes, feeding modes and steel grade manufacturing standards.

Q: What is Calcium Silicon 30–60mm used for?
A: Calcium Silicon 30–60mm is mainly used for ladle treatment, deoxidation, desulfurization and inclusion modification in steelmaking. You can use it when your molten steel needs calcium and silicon treatment before casting.

Q: Why choose 30–60mm calcium silicon lumps?
A: The 30–60mm size is practical for weighing, storage and ladle addition. It helps reduce excessive dust loss compared with fine material and is easier to handle than oversized lumps.

Q: What composition should I check before buying calcium silicon?
A: You should check Ca, Si, C, Al, S and P. Calcium and silicon are the main active elements, while C, S, P and Al should be controlled according to your steelmaking requirement.

Q: How do you pack calcium silicon for export?
A: We usually pack calcium silicon in 1MT FIBC jumbo bags. Moisture-proof packing or customized export packing can be confirmed according to your storage and shipment requirements.
