The utilization of aplite in ladle desulfurization of cast iron
MetadataShow full item record
The desulfurizing powers of aplite, aplite-soda ash mixtures, and aplite-dehydrated lime combinations when added to a ladle of cast iron were tested. Ladle conditions were simulated by melting cast iron in a crucible and introducing the reagent mixtures into the molten metal by means of a cast iron cup and steel rod. It was found that in every case the desulfurizlng power was appreciably below that of soda ash and did not warrant testing the mixture to determine its effect upon the corrosion of ladle refractory linings.
