Diameter etc.) partial size as object construction unit.
Step S23 determines the target grain size according to the partial size of the target gap width or the object construction unit；
Since the solid particle of different-grain diameter can be correspondingly formed different gaps, the partial size of solid particle is bigger, Duo Gegu
When the compact splicing of body particle, the gap between solid particle is just bigger.Based on this principle, different gap widths can be corresponding with not
The partial size of same sand material, can determine the partial size of corresponding sand material as target grain size according to determining target gap width.
In addition, it is identical that the identical solid particle of partial size forms gap when the shape of solid particle is identical.It therefore, can be first
Determine whether the shape of the object construction unit in matrix is consistent with sand material, if unanimously can be directly by the partial size of object construction unit
As target grain size；If inconsistent, the conversion coefficient of pore size between two kinds of shapes can be obtained, according to object construction unit
Partial size and conversion coefficient calculate target grain size.
Step S24, according to the spare sand material of the target grain size screen analysis；
