Korea Iron & Steel Association Chapter 3●Tour of a steel mill

Look. It glows! Wow, it looks
like lava! The molten iron
in the furnace is incredibly
Iron ore (sintered ore) + coal (coke) + limestone
hot. That’s why it glows.
Hot air

Iron ore (sintered ore), coke, and
limestone are piled layer by layer in the
furnace.
Then, 1,200℃ hot air is blown in.
When the coke that serves as fuel
burns, it generates heat measuring up
to 2,300°C, causing the iron ore to melt.
Molten It may look like simple high heat is used to melt iron. However, the quality of the

Korea imports steelmaking raw materials, iron ore and coal, from other countries such as Australia, When molten iron flows out of the furnace, the temperature inside the work area rises close to
