| Abstract: | With suitable ratio of charging and de-sulfur at running gate of cupola, the molten iron can meet the requirement of compacted graphite iron. With suitable composition, melting and nodularizing, and squared side risers, the RUT340 CG cast iron cylinder cover can have more than 75% nodularized graphite, more than 98% pearlite in volume, grade 4 graphite length. The reject rate is lower than 8%. |
