Effect of lime on sintering

To speed up sintering, improve the quality indices for the charge’s agglomeration, and reduce the consumption of solid fuel, it is best to use milk of lime and hold crushed lime with the concentrate before the sintering operation. The addition of lime to the sintering charge at the Severstal’ Metallurgical Combine is most effective when its unit consumption is within the range 20–40 kg/ton sinter.
