INVESTIGATION OF CARBON INFLUENCE IN CROMIUMIUM CAST IRONS FOR FORMING CASTINGS IN SAND AND COMBINED MOLDS

Abstract

The results of research to determine the influence of the amount of carbon in chromium cast irons on the formation of castings in sand and combined molds are described in the article. Experimental studies were carried out with casting samples from wearresistant cromium cast iron with different carbon contents. The microstructure of the obtained samples is presented, and its analysis is performed. Numerical studies have been carried out to evaluate the effect of the carbon content on the dynamics and kinetics of hardening of castings in sand and combined molds. The influence of the carbon content on the hardening process of cromium cast iron castings during foundry casting in sand and combined molds is established. The results of the research were used for the manufacture parts of crushing and grinding equipment.
