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 blast furnace is a complex high temperature counter current reactor and is in the shape of a shaft in which iron bearing materials (ore, sinter/pellet) and coke are alternately charged at the top along with flux materials (limestone, dolomite etc.) A blast furnace is a gigantic, steel stack lined with refractory brick where the concentrated iron ore, coke, and limestone are dumped from the top, and a blast of hot air is blown into the bottom. Blast furnaces are used continuously and are coke and limestone They are then used to help heat the air blast, required if blast furnace is to reach the high . It is then removed and cooled into hardened slag. 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. 100% correct and accurate. Blasts furnaces are used for smelting during the production of metals such as iron, lead, zinc, and copper. This is molten at blast furnace temperatures and floats on top of the molten iron.
