The most prominent works are indicated with numbers in the accompanying picture.
The fireproof lining in a blast furnace can resist extremely high temperatures; this is essential, considering that the temperature of the liquid hot metal is approximately 1,500 degrees Celsius. The lining in the blast furnace needs to be replaced. New fireproof brickwork will ensure the maintenance of the furnace. It will also ensure that the work environment remains safe.
Special trains (called ‘torpedoes’) take the liquid hot metal produced in the blast furnaces from the ‘tapholes’ of the furnace to the steel plant. Dust may be released when these tapholes are opened and closed.
These additional extraction facilities are expected to reduce dust emissions during the tapping of hot metal by approximately 75%.
Blast furnace gas is released during production. It is captured and cleaned by the gas cleaning system. This happens through a downcomer. Eventually the gas arrives at the stock yard and can then be reused again. These works will also be unnoticeable to the surrounding inhabitants. The repairs will contribute to reduced dust emissions.
