Abstract

Чугун, содержащий, мас.%:отличающийся тем, что, с целью снижения склонности чугуна к образованию фосфидно-цементитной эвтектики и улучшения обрабатываемости, стабилизации перлитной структуры и сохранения повышенной прочности в него дополнительно вводится комплексная добавка, состоящая из 14% Bi; 14% Se; 14% Zn; 9% B; 7% Sb; 7% Sn; остальное Pb, в количестве от 0,03 до 0,10% масс при следующем содержании основных компонентов, мас.%:Cast iron containing, wt.%: Characterized in that, in order to reduce the tendency of cast iron to form a phosphide-cementite eutectic and improve machinability, stabilize the pearlite structure and maintain increased strength, an additional additive consisting of 14% Bi is additionally introduced into it; 14% Se; 14% Zn; 9% B; 7% Sb; 7% Sn; the rest of Pb, in an amount of from 0.03 to 0.10% of the masses with the following content of the main components, wt.%:
