The first step to concentrate the iron ore and remove its contents of silica. To further remove any existing impurities, a complex process takes
Grey cast iron is the most widely used foundry alloy in the world due to its wide range of achievable mechanical properties, good castability, excellent wear resistance and damping properties, high thermal conductivity as well as low cost (20-40% less than steel) (Xu et al., 2005). It is used in such diverse applications as cookware and musical instruments to auto parts and heavy machineries. Microstructure of grey cast iron is characterized by dispersion of graphite flakes in a ferrous matrix. It

Technically this was the first flat iron, but of course
Iron is this starting point for steelmaking which has performed as a backbone to the advancement of modern technology and is vital to the upbringing of the future. It acts as the predominant reason for the industrial revolution. The foundation that is iron, more industrially known as Cast Iron has been given the second honour as it is the one of the cheapest materials for engineering, when taken to molten temperatures it gains the ability to be cast into intricate shapes. Cast Iron has been sub-divided

Manufacture Of Iron By Blast Furnace Process Iron is a naturally occurring element in its ore form (Haematite), however for iron to be of any use the impurities must be removed. This is done by a process involving a blast furnace. Extremely high temperature in the range of 870°C are reached within the blast furnace and this heat causes reactions to occur within the blast furnace that remove some of the impurities from the iron ore. The materials placed in the blast furnace are iron ore, coke
