Sažetak
A technological analysis of the vacuum furnace application for hardening of tools and dies with respect to heating and quenching requirements has been performed. It was noted that in modern vacuum furnaces the hardening process is performed mainly under gas atmosphere but under vacuum conditions only at the beginning during air evacuation. Analyses show that the hypereutectoid carbide precipitation cannot be avoided due to the insufficiently fast cooling in the high pressure gas quenching. A design of an integral quench furnace with a closed system of introducing the noble gas, i.e. argon or helium, and of quenching in a hot oil bath has been developed. The new design reduces the possibility of carbide precipitation and also reduces thermal stresses applying thermal hardening.
