Studies of cooling circuits as part of the refurbishment of the B Arcelor Mittal blast furnace in Ghent, Belgium.


ArcelorMittal in Ghent, Belgium has 2 blast furnaces which form the heart of their production. Blast furnaces operate for 20 to 25 years, after which the refractory lining must be renewed.

Our teams intervened for the repair of blast furnace B. They carried out basic and detailed studies of the cooling circuits, gas washing circuits and a granulation circuit outside the square tower.

The new blast furnace is more efficient in terms of fuel consumption thanks to the recycling of wood waste as well as the injection of waste gases and plastic .
