Increased productivity and quality through conversion of secondary cooling to air-mist system on beam blank, bloom and round combi caster
The 4-strand combi caster at SMS-II of Jindal Steel & Power Ltd commissioned in 2003, was designed to produce two beam blank section sizes, two bloom sizes and four sizes of rounds. As demand increased and the product range extended, caster productivity, casting speeds and product quality did not meet the necessary standards needed. Lechler assessed the secondary cooling system and designed and installed an air-mist system to replace the existing water-only system for the beam blank sizes. Significant gains in productivity and quality have been achieved. The strands will now be converted for use with blooms and rounds.
