INVESTIGATION OF GAS RELEASE FROM MOLDS

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.
