Urgently!! Refractory problems, online, etc.
I feel that is the coating package, the coating of water is too large, the retaining wall in fused powder hydrated, can not produce strength under high temperature. What do you think?
Uneven contraction. When the magnesia block wall is made, the steel wire mesh can be added to the magnesium block wall. That will solve the problem.
The service life of most refractory materials is a pair of contradictory effects. As a result, one aspect of the contradiction is porosity, and the other is volume density. The larger the volume density is, the smaller the porosity is and the more erosion resistant, but the thermal shock effect is very poor. The bigger the porosity is, the smaller the volume density is, the better the thermal shock effect is, but it is not resistant to erosion. More professionally, two curves should be made to find the intersection of the curves to adjust the recipe and production process
