FERROUS METALS AND ALLOYSPRODUCTION,GENERAL PROPERTIES ANDAPPLICATIONS(Introduction of ferrous metal)(Production of iron and steel)
WHAT IS ferrous metal Ferrous metals are those which contain iron,whilst non- ferrous metals don’t have any ironcontent.. Ferrous metals and alloys containing a highproportion of the element iron. They are the strongest materials available andare used for applications where high strengthneeded.
When iron &steel was foundC:UsersHamshaDesktopUddeholm - Tool Steel of World Class.mp4 The production of iron by humans began probablysometime after 2000 BCE in south-west or south-central Asia, perhaps in the Caucasus region. The basic source of iron and steel is iron ore,which is an oxide of iron mixed with alumina,silica, phosphorous, manganese, sulphur andother materials.

Other raw materials in iron making. Coke (C)- Supplies heat for chemical reactionsand produces carbon monoxide (CO) toreduce iron ore. Limestone (CaCO3)Used as a flux to react with and removeimpurities in molten iron as slag. Hot gases (CO, H2, CO2, H2O, N2, O2,and fuels)Used to burn coke

WHY IRON AND STEEL IS WIDELY USED IN THEMANUFACTURING INDUSTRY?High quality, aesthetic.Low maintenance costs.Steel is noncombustible.Environmentally friendly.Components can be re-used.Strong, durable and stable.Construction is fast compared to othermaterials.Resistant to termites and other destructiveinsects.Cost benefits compared to otherconstruction methods.Components are functional.
Who uses the iron andsteel? In the motor vehicle industry. Aluminum. Concrete and wood in construction.
How does iron and steelproduction affect ourmanufacturing industry? Organizational structure, productivity,efficiency, and product properties of thesteel industry worldwide. Reliability ,energy, materials efficiencyof conventional processes.
