What are the factors that affect the density of reduced iron powder?

1. The main function of reducing iron powder:

(1) shape the powder wood into the required shape;
(2) the shape and size of the blank body should be given to the body, and the size of sintering should be considered;
(3) the porosity and pore type required by the blank body;
(4) give the body a proper strength for carrying.

2. The relationship between the density and the influencing factors:

(1) increase with the increase of pressing pressure;
(2) increase with the particle size or the density of the pine;
(3) the strength and hardness of iron powder particles are reduced, which is beneficial to increase the density of compact;
(4) reduce the pressing speed and increase the density of the blank.
 
It is one of the important symbols to reflect the quality of iron powder.
For any metal powder, the mechanical meshing force between the powder particles is the main coupling force of the pressure.
