Although not an area that one might wish to gain a lot of experience in, the technique applied by Danieli Corus for the recovery of blast furnaces with a chilled hearth has been tried and tested on all continents during 37 projects. Danieli Corus has developed special “oxyfuel lance technology”, which is used in about half of the recoveries. The measures differ depending on the extent of the chill, and early notification is always recommended for the quickest recovery. Our lance system, based on our proprietary oxy–fuel technology, is always on stand–by for delivery and can be on–site within 48 hours worldwide.
No two recoveries are the same, but our team of experienced operators have proved able to adapt to any situation, providing advice at all stages of the recovery to ensure a rapid and stable return to normal operations.
