Times reduced iron iron is a short, usually referred to in the powder metallurgy industry was once again reduced iron or iron powder once. A powder production process is very cumbersome, reduced iron production requires a good time to start cargo of iron oxide skin scales election since the general election of high grade iron impurities less iron oxide skin and scales, removing one of the big iron iron sheet drying. (Note, iron oxide skin is falling iron steelmaking slag is generally remove from the quench tank, the moisture content is too high) magnetic separation after drying, remove impurities, and then milling, stowage sintering. Kins powder metallurgy factory in Suzhou strictly guard the quality, eliminate production of defective shipments.
