BackgroundHistoryThe Manufacturing ProcessQuality ControlByproducts/WasteThe FutureIron is one of the most common elements on earth. Nearly every construction of man contains at least a little iron. It is also one of the oldest metals and was first fashioned into useful and ornamental objects at least 3,500 years ago. Pure iron is a soft, grayish-white metal. Although iron is a common element, pure iron is almost never found in nature. The only pure iron known to exist naturally comes from fallen meteorites. Most iron is found 在madehow上查看更多信息

Process for Manufacturing of Iron Carbide – IspatGuru
