Iron powder is the basic raw material powder metallurgy industry, the world attach great importance to the production of iron. The world's annual production of over 100 million tons of iron, China has more than 30 million tons of production capacity, which reduced iron production accounted for 60%, mainly in the Anshan Iron and Steel Group, Wuhan Iron and Steel, Maanshan Steel and other large steel companies and has a super-iron iron ore powder production enterprises. Iron production, quality directly affects the development of magnetic materials industry and metallurgy industry, thus directly affect many industries automotive, electronics, household appliances, telecommunications, machinery manufacturing. As we all know, with the iron manufacturing machinery parts, its material utilization rate of 95% or more, while cutting metal materials, the material utilization at about 45%, the international general considered the equivalent of one ton of iron products 3 utilization of tons of steel.
