Nodularizing additive for casting high strength nodular graphite cast iron
TLDR
In this article, a casting alloy for the production of cast pearlite nodular cast iron is presented, which contains Mg 5-9 wt, Ca 3.5-5.0 wt., Ba 1.0-3.5 wt.Abstract:
The present invention refers to a casting alloy, esp. nodulizer for production of cast pearlite nodular cast iron. The said nodulizer contains Mg 5-9 wt%, Ca 3.5-5.0 wt%, Ba 1.0-3.5 wt, Si 35-50 wt%, Sb 0.5-4.0 wt, and balanced Fe. The nodulizer thus made is a lump alloy, available size in two variants: 3-25 mm and 25-100 mm.read more
