Thermal Processes in Pouring into Ceramic Shells and their Numerical Solution

Popis výsledku v původním jazyce

In the thermal regime of ceramic shell moulds made by the lost wax process the role of heat transfer by radiation or convection into the surrounding environment is significant while the portion of heat accumulated in the mould is less important. In ceramic shells the walls are mutually irradiated and there appear non-symmetrical heat flows in the direction of the axis of clusters and out of the clusters. Heat relations have up to now received little attention and no verified thermo-physical parameters are available for numerical simulation. Experimental measuring was used to establish the heat relations during casting and solidification of a model system of cylindrical castings of different diameters, which were placed on a ring gate. Thermocouples were used to measure the temperature behaviour in individual castings and in the walls of ceramic shells. The casting material was the N155 alloy based on iron, nickel and cobalt. The experimentally established data were used as significant
