RH-47 is utilized for the cleansing of treatment ladles and iron melts.
Some additional features of RH-47 include
Increased fluidity of the melt
Fading is retarded
Reduction of slag build-up in ladles or treatment chambers greatly extending ladle life
The addition rate of 0.1% of melt is recommended, RH-47 should be put in the ladle with the ductile iron treating agent (i.e MgFeSi). As an added savings, an equal amount of MgFeSi can be removed from the treatment.
A 10% addition of the post inoculant, together as a mix. For example if the post inoculant addition is 5lbs a 0.5lb of RH-47 is recommended.
