Abstract

Carbide component and cast iron matrix have a significant effect on the operational properties of cast iron parts. The results of investigations of the effect the heat treatment on the composition of the carbide phase alloyed cast iron used for the production of large castings used in metallurgy are given. Heat treatment in the range of temperatures from 300° to 600°C does not significantly change the composition of the carbide phase relative to the cast state, however, it approximates its state of Fe and C to the stoichiometric composition, which increases its stability during operation
