THE BLAST FURNACE

Blast furnaces are used continuously and are only shut down when their brick lining needs replacing. As the mixture of iron ore, coke and limestone heats, the hot waste gases are collected and cleansed. They are then used to help heat the air blast, required if blast furnace is to reach the high temperatures needed to produce molten iron.
