Blast Furnace Iron | Iron and Steel | Howden

The Blast Furnace is designed to reduce iron oxides and to separate the resulting iron from the large quantities of impurities in the ore. Blast furnace fans are essential to drive heated air into the furnace and our ID fans are then used to draw the furnace gases. Where a cooling tower exists, our cooling fans are an important way to remove heat.
