Low Creep Fireclay Brick
It is made of high quality fireclay clinker as main material by shaping at high pressure and sintering at high temperature.
Advantages:
This product has advantages of high refractoriness under load, good creep resistance at medium temperature and good impacting resistance.
Application:
It is the main refractory for positions with medium and low temperature hot blast stove.
