ABSTRACT:
A method of producing castings comprising the steps of: pouring moulds with inoculated cast iron containing, by weight per cent: carbon 3.6-3.8, silicon 2.8-3.2, manganese up to 0.4, magnesium not more than 0.01, at a melt temperature ranging from 1420.degree. to 1450.degree. C, and subsequently cooling the cast iron. The thickness of walls of the castings is chosen so that the initial cooling rate is 10.degree.-14.degree. C/sec with a preset heat conductivity.
