Red River Formation in Kiln Operations
Kiln temperature: Inconsistent temperature control in the kiln's burning zone, often exceeding 1500°C, creates an imbalance between the solid and molten clinker phases, leading to red river formation. Maintaining temperatures within a more stable range of 1470-1490°C ensures that the clinker remains solid as it moves into the cooler.
