Iron melting control of large-section cast ferrite ductile iron partsBy Shengrong High End Equipment Manufacturing on 30/04/2025The pouring should adopt the principle of fast pouring and steady injection. In order to improve the uniformity of instantaneous inoculation and prevent slag from entering the cavity, the total capacity of the nozzle basin should be equivalent to the gross weight of the casting. When pouring, put the inoculant in the nozzle basin, and inject all the molten iron into the nozzle at once to fully mix the molten iron and the inoculant, scrape off the surface slag, and raise the nozzle to block the pouring.
