Sintering Process Carmeuse

2021-10-8  Burnt lime, as compared to limestone, improves the heat transfer in the sintered layer. At the same basicity and the same volume of fuel, a change in the CO 2 /CO ratio can occur, due to the different amounts of carbonates after their replacement by lime. For lime too, the quality, granulometry, quantity, and method of lime addition to the agglomeration process are critical to sinter
