Solidification Time (Chvorinov's Rule) Calculator

Solidifcation time (t_s):

Volume of the casting (V):

Surface area of the casting (A):

Mold constant:

Exponent (n):

How This Is Calculated

$$ t_s = C \left(\frac{V}{A}\right)^n $$ where:

t_s = Solidifcation time (s)

V = Volume of the casting (m³)

A = Surface area of the casting (m²)

C = Mold constant (s/m³)

n = Exponent typically between 1.5-2 (dimensionless)

Assumptions

Heat transfer is uniform.
Conduction is the dominant mode of heat transfer.
The mold and casting are in thermal equalibrium.
There are no external cooling or heating effects.
