Oct 21, 2020 The production of iron and its alloys involves three main components limestone, coke bituminous coal and iron-ore. These materials are placed into the top of a blast furnace which is a large steel cylinder lined with brick. The melted concoction is blasted into the furnace through nozzles.

The Blast Furnace

The Blast Furnace

The blast furnace is a huge, steel stack lined with refractory brick, where iron ore, coke and limestone are dumped into the top, and preheated air is blown into the bottom. The raw materials require 6 to 8 hours to descend to the bottom of the furnace where they become the final product of liquid slag and liquid iron.
