Identification marking of refractory castables:

a b c d e f
B N S 30 SiC B  
B N   75 B X
B N O 82 B  
B U S 80 V  
BB B S 85 Mg  
  1. a. B – refractory castable
  2. b. N – low cement castable
        U – ultra low cement castable
        B – no cement castable
  3. c. S – self-flowing 
        O – repairs
  4. d. 80 – Al2Ocontent in %<
        BNS30BSiC – content of SiC in %
  5. e. L – calcinated fire-clay-based
        A – andalusite-based
        V – high-alumina aggregate-based
        B – bauxite-based
        HK – brown-fused alumina-based
        K – corundum-based
        T – tabular-alumina-based
        BSiC – SiC-based with bauxite
        SiCC – SiCC-based
  6. f.  X – for special use
