Crushing Of The Ore In Blast Furnace

Sep 13, 2021

General view of machinery used to crush ore at the Fixed Nitrogen Research Laboratory's blast furnace plant. A worker identified as Parker is seen transferring raw material, presumably ore, from a machine into a wheelbarrow for transport. The Fixed Nitrogen Research Laboratory (F.N.R.L.) was established at American University in 1919 under the directorship of Arthur B. Lamb. Initially part

    This extraction method is still used today. The bloomery is replaced with a blast furnace, but the chemistry is still the same. Iron ore, a type of coal called coke (which contains 85% carbon) and lime are added to the top of the blast furnace. Hot air provides the oxygen for the reaction. The temperature of a blast furnace can be up to 1200 C

    A synthetic aggregate may also be the byproduct of manufacturing and a final burning process—blast furnace slag is an example of a synthetic aggregate. Briefly, blast furnace slag is formed when iron ore or iron pellets, coke, and a flux (such as limestone, CaCO 3, or dolomite, CaCO 3 MgCO 3) are melted together in a blast furnace. When the
