Zusammenfassung:The method for manufacture of high-strength casting molds includes smelting of cast iron, pouring cast iron into the ladle pot, working cast iron by magnesium in the ladle pot, subsequent pouring of cast iron into the pouring ladle, and casting-up. Cast iron is melted with phosphorus content not more than 0.05 %. Then the working cast iron by magnesium is carried out in the ladle pot. During pouring cast iron into the pouring ladle the alloying and modifying additives are introduced.
