Изобретение относитс к области ферросплавного производства.This invention relates to the field of ferroalloy production.
Известен сплав дл обработки серого чугуна , содержащий хром, кремний, марганец и железо.A known alloy for the treatment of gray iron containing chromium, silicon, manganese and iron.
С целью повышени качества чугуна в состав сплава введен кальций и компоненты вз ты в следующем соотнощении, %:In order to improve the quality of cast iron, calcium is introduced into the alloy and the components are taken in the following ratio,%:
Хром35,0-45,0Chrome 35.0-45.0
Кремний20,0-28,0Silicon20.0-28.0
Марганец5 0-15,0Manganese5 0-15,0
Кальций0,1-5,0Calcium0,1-5,0
