Do you know the refractory materials’requirements for the sodium silicate furnace?

2015/2/10      view:
  The refractory material used in the sodium silicate furnace should not only have the basic characteristic which used in the normal industrial furnace, but also should satisfy the sodium silicate’s special melting process, which include:
  1) High refractoriness;
  2) High temperature mechanical strength; 
  3) Perfect high temperature volume stability;
  4) High resistance to erosion of liquid sodium silicate, Alkaline waste material and flame;
  Furthermore, the refractory material should not have pollution on the liquid sodium silicate, which has good thermal stability and strict dimensional tolerance.
