Resumo
The blast furnace 5 was shutdown in the end of 1999 and its gas cleaning system equipment was utilized in the blast furnace “A” (BF-A). The levels of free droplets and dust contents were excessively high, affecting the hot stoves performance since BF- A started up on December 19 , 1999. The new gas cleaning system of the blast furnace “A” is provided with a cyclone, reducing the amount of mud to be treated and causing minor impact to the environment. With the new gas cleaning system, ArcelorMittal eliminated a bottleneck and prepared the blast furnace “A” to the production of 1.2 Million tons of hot metal / year, assuring the blast furnace gas quality within the required standard.
