Mastery of slag design in secondary metallurgy is crucial to performance in steelmaking. It guarantees the quality and cleanliness of the steel and the consistency of its performance. Thanks to it its special physical and chemical properties, calcium aluminate flux achieves rapid formation of slag and efficient steel refining in secondary metallurgy, in the continuous casting tundish, and in foundries.
- Calcium-aluminate cements are primarily used for high heat refractory applications.
- Other uses include moderate acid-resistant applications, high-early-strength and quick-setting mixtures, and as part of the expansive component in some shrinkage-compensating cements.
- These cements are typically designed to gain strength much faster than ordinary portland cements and predominately consist of calcium aluminate that can produce large amounts of heat during the first 24 hours.
- The cement phase ratios (CA or CA2) are proportioned according to the intended application performance characteristics.
