Alternative Classifications
This product could be classified differently depending on its characteristics or intended use.
If imported assembled in steel ladle
Complete steel vessels with refractory lining classified by predominant steel material.
If aluminum oxide-graphite mix ≤50% carbon
Common ladle refractories blend materials, changing heading based on carbon dominance.
If unfired chemically bonded mixes
Prepared refractory cements and mortars exclude unfired products from Chapter 69.
