Question

In blast furnace, there is a steady increase in temperature from bottom to top.

• A. True
• B. False

Answer 1

The correct option is B False

Purpose of a blast furnace is to chemically reduce and physically convert iron oxides into liquid iron called "hot metal". At furnace temperature of about ${1800}^{o}C$, give or take ${200}^{o}C$, these liquid products are molten and trickle down to collect in the base of the furnace where they are extracted at regular intervals.
