The paper aims to describe the dependence of cooling rate of a ceramic shell on the number of refractory slurries and on the way of insulation in investment casting process. The infrared thermography was the basis for measurement of temperatures during experiments. This method has not been used during Investment Casting process yet according to scientific databases. From a plenty of experiments there are shown the top results in this paper. The point was to investigate the cooling behaviour of ceramic shell to find out the dependence of a decreasing temperature on time. This knowledge is essential in determining the maximum period of time to assure the minimum required preheating temperature of the ceramic shell. [ABSTRACT FROM AUTHOR]
