Ron Powder Reduced Iron Powder Sponge Iron

Reduced iron powder, gray or black powder, also known as "double-suction", can absorb moisture and oxygen in the air, and is often used for food preservation.
The reduced iron powder is generally produced by the reduction of ferroferric oxide in a hydrogen stream or a carbon monoxide gas stream under high heat conditions, and the main component is a structurally loose elemental iron. Since the reduced iron powder itself is powdery, and its microstructure is very loose, its surface area is extremely large. It is often used as a high quality reducing agent in chemical production and laboratory operations.
INDEX
The equations for reducing iron powder commonly used in middle school chemistry courses are:
3Fe+4H2O(g)=high heat=Fe3O4+4H2
The common method of reducing iron powder is to use a solid or gaseous reducing agent (coke, charcoal, anthracite, water gas, natural gas, ammonia, hydrogen, etc.) to reduce iron oxides (iron concentrate, rolled steel scales, etc.) to make sponge-like iron.
During the reduction process, it is divided into (solid carbon reduction) primary reduction and secondary reduction.
One reduction is the reduction of solid carbon to prepare sponge iron.
The main process of one reductionis: (iron concentrate, rolling steel scales, etc.) → drying → magnetic separation → crushing → screening → canning → entering a reduction furnace → sponge iron.
Secondary fine reduction process:sponge iron→clearing→crushing→magnetic separation→secondary reduction furnace→powder→disintegration→magnetic separation→screening→grading→mixing→packaging→finished product.
