Lime Calcination
|
| |
| Lime calcination facility produces calcium oxide (quicklime) through the reduction of mined calcium carbonate (limestone). The produced lime is mixed with melted iron to eliminate impurities and facilitate the formation of slag for improving the quality of melted iron. In addition, lime generates a large amount of heat, which is ideal as a heat source in the sintered ore production process.
POSCO E&C maintains high competitiveness and comprehensive know-hows for the construction of lime calcination facilities, and has successfully performed the engineering, procurement, construction, and commissioning of a number of facilities based on these proven technologies. |
