In work it has been presented results of influence of pouring temperature (Tp) and carbon equivalent (CE) on castability of ductile iron in thin walled castings with wall thickness of 1, 2 and 3 mm, respectively. Analysis was done on ductile iron with carbon equivalent ranging from 4.30 to 5.00 and pouring temperature varied from 1400 to 1500°C. It has been shown that a statistical liner relationship exists between wall thickness and castability. Influence of CE and Tp on castability of cast iron flowing through channel with wall thickness of 2 and 3 mm can be presented by means of correlation equations (L= f(CE,Tp)). Statistical analysis shows that pouring temperature has much higher influence on castability in comparison with influence of carbon equivalent.
