KZB 4 up to 1600 °C

Refractory castable shapes made of KZB 4 are extremely resistant to changes in temperature and to abrasions. They are used in places where high demands are placed on the accumulation properties of shapes. This usually means the linings of fireplaces, fireplace liners, fire pots, combustion paths (their permanent linings), accumulation shaped blocks, grates, and grate assemblies.

I want shaped blocks made from this mixture
