The casting process, metallographie structure, thermal conductivity, anti-oxidization and anti-abrasion of the cast-iron glass container moulds have been presented together with the measures for fining graphite structure of the semifinished moulds. Moreover, the metallographie standards, technical data and the practical use of compated vermicular graphite east-iron have also been described. It can be observed that the serviee-lifo of the moulds from rare-earth compated vermicular graphite cast iron is obviously longer than that of the moulds from alloyed gray east-iron.
