A mathematical model of gas release from a mold in the 
stage of solidification and cooling of metal has been constructed. 
The model includes heat and mass transfer on the mold's capillary-porous 
medium containing phenol-formaldehyde resin as a binder; it also includes 
the kinetics of pyrolysis of the resin and secondary chemical reactions 
between the products formed. The process has been investigated experimentally. 
It has been shown that the model gives a fairly good description of 
the process in a wide range of variation in its parameters within 
the framework of the assumptions made.
