Sažetak
Production of vermicular cast iron by method of exact addition of alloy for melt treatment based on Mg is difficult due to very narrow range of residual Mg, which is often less than ± ; 0, 001%, what is difficult to obtain due to process’ s variables. Microstructure of vermicular cast iron is highly sensitive to the section thickness of casting, relatively cooling intensity, which requests optimizing and strict control of production parameters with the purpose of obtaining requested properties of vermicular cast iron castings. In this paper influence of cooling intensity on obtained microstructure properties and hardness of casting of vermicular cast iron have been analyzed. It has been ascertained which increase of cooling intensity results in high proportion of nodular graphite and pearlite in microstructure and increases hardness of vermicular cast iron.
