Iron powder, reduced iron is an important raw material of iron-based powder metallurgy products production, and its performance directly affects the quality of the iron-based powder metallurgy products. In order to get good performance of the products, we must strictly control the physical properties of iron, chemical properties and process performance. Iron-based powder metallurgy products, raw iron production requires a stable bulk density, higher compression and formability. Iron is an important raw material powder cold whole oyster production of products, it can directly affect the quality of long iron-based powder metallurgy products. In order to get good performance restrain grain, iron powder must be strictly controlled physical properties, chemical properties and process performance. Iron-based powder metallurgy products, raw iron production requires a stable bulk density, higher compression and formability.
