Identification marking of refractory monoliths:

a b c d
BN 82 B 3
  1. a. BH – Dense castable 
  2.     BNS -LCC self flowing castable 
  3. b. 82 – content of Al2O3 in %
  4. c. L – Fireclay – based
       B – Bauxite – based
       K – White fused alumina – based
  5.    A – Andalusite – based
       HK – Brown fused alumina – based
  6.    TS – Tabular – alumina – based 
  7.  
  8. d. 3 – max. grain size
