METHOD OF GREY CAST IRON TREATMENT BY NANO-SECOND ELECTRO-MAGNETIC PULSES (NEMP) FOR IMPROVING HEAT CONDUCTIVITY, CORROSION STABILITY AND HEAT RESISTANCE

摘要

FIELD: metallurgy.;SUBSTANCE: invention relates to foundry production. The method provides for heating and electromagnetic treatment of melt by nano-second electro magnetic pulses. The melt is heated to 1500°C and cured under the above temperature during 5 minutes. The melt is subject to electromagnetic treatment at 1350°C during 10 minutes.;EFFECT: improved heat conductivity and heat resistance of melt.;2 ex
