Analysis of the technological efficiency of temperature stabilization of shell ceramic molds before pouring

The analysis of the data characterizing the effect of the molding method on the cooling of ceramic molds after tempering showed that the longest stability of the mold temperature is observed with the methods of molding ceramic molds into a granular support filler and a thermostat. Moreover, by changing the thickness or material of the heatinsulating layer of the thermostat, it is possible to adjust the duration of thermostating of the ceramic mold within wide limits, and thereby control the processes of casting formation and its quality. It has been established that during molding in a thermostat, the sufficient duration of calcination of ceramic shells at 950...980 0C is about 1 hour.
