Low Creep Fireclay Brick Fireclay Refractory For Hot Blast Furnace
Low Creep Clay Brick for Hot Blast Furnace
Low Creep Clay Brick for Hot Blast Furnace/Low creep rate/Small high temperature creep/High load weight softening temperature/Good impact resistance/High pressure-resistant strength
Summary:
Low creep clay refractory brick is made of high quality refractory raw materials with less impurities, dense structure and high purity as the main raw material, adding new refractory raw materials and additives, binagent, after the formula proportion ingredients, mixing, high pressure molding, high temperature sintering, has the advantages of small creep rate, strong heat storage capacity.
Product features:
- 1.Creep rate is low, and high temperature creep is small.
- 2.High load weight softening temperature;
- 3.Good impact resistance;
- 4.High temperature and high pressure-resistant strength
- 5.High temperature volume stability, good wear resistance
Range of application:
Suitable for large, small and medium blast furnace, mainly used in the middle and lower wall of heat storage, lower lattice bricks, support strings and other parts
