The Reline of ROGESA's No. 4 Blast Furnace in 2016: Technical Upgrades Performed During the Revamping Project

摘要

After 90 days of stoppage, ROGESA's blast furnace n°4 started its fifth campaign on the 29th of September, 2016. With a hearth diameter of 11.2 meters, its daily target hot metal production is 6,500 tons. During the plant reline, important modernizations have been implemented. Extended charging flexibility, an optimized BF profile, the cooling elements design and arrangement, as well as improved hearth monitoring will support both a better process efficiency and reaching the target of a 15-years campaign. The solutions for the hot blast generation and supply systems will contribute to the necessary process stability. A modern top gas cleaning concept reduces the output of critical BF sludge and thus the environmental impact of the blast furnace operations.
