Blast Furnace Process

Blast Furnace Process A blast furnace is a steel cylinder lined with refractory It operates continuously until the lining wears out which takes many years to occur The term blast furnace comes from the blast of hot air that is blown into the lower part of the furnace at between 1400 to 2100 F Molten iron is produced in a blast furnace
