The main factor of refractory high temperature creep

The factors that affect the high temperature creep of refractory are many, and many factors are interrelated… The main factors that affect the creep deformation of refractory are the following:

1, refractory material, including: chemical composition, mineral composition (single phase or multiphase), microstructure.

2, the outside conditions in effect, including: temperature, load, and time, atmosphere (oxidative or reductive).

3, the chemical mineral composition and microstructure of refractory materials determine the creep resistance of the materials.

4, in phase composition to determine the basic conditions, high bulk density, compressive strength, porosity low refractory products, creep resistance is better, but with the increase of temperature and time increase, refractory material stress will be increased creep deformation will increase.
