Abstract
Procedure for hardening foundry cores of a mixture containing sand, in which the core is subjected to a mixture of catalyst steam and carrier gas for its hardening in the madras mold and then to a stream of compressed air with respective volumes. previously established, previously established pressures and previously established temperatures, characterized in that both the catalyst and carrier gas mixture as well as the compressed air are temporarily stored in respective dosing containers and are subsequently fired consecutively from these dosing containers into the tap, the compressed air being stored with a greater volume and heating it to a higher temperature than the mixture of catalyst steam and carrier gas.
