When laying refractory bricks, you need to be prepared to take precautions. During the construction process, it is easy to be disturbed by various problems. Then, only with adequate work and timely preparation before construction, we can do better and faster. In order to avoid the possibility of failure, let us look at the refractory bricks fall off the reason to.

1, red-hot refractory bricks are suddenly subjected to water cold excitation produces rupture and fall.

2, the oven stage heating rate is not strict, lift the temperature too fast, resulting in masonry due to intense dehydration, expansion and contraction and damage.

3, build the furnace masonry upward expansion margin left insufficient, after warming up the expansion of extrusion and fall.

4、System ash accumulation, most of the metal salts on the refractory bricks have erosion, vanadium and nickel will penetrate into the refractory bricks caused by brittle bricks off.

5、When warming up the liquefied gas, air flow ratio is not appropriate, resulting in combustion explosion in the furnace and vibration crack off.

6, poor airflow in the furnace, the flame has a direct scouring of the furnace bricks, so that the furnace brick thinning serious fall.

7, the operation is too violent, the furnace temperature and pressure of the lift to strive for balance, forbidden temperature and pressure, do not rise and fall, because the temperature change of the brick layer is always lagging behind the temperature of the hearth, the more by the outer layer of the slower the temperature change, if a short period of time the temperature of the hearth drastic changes in the brick layer will be too large a difference in temperature to produce huge internal stresses caused by the refractory bricks and bricks rupture seam. The sudden rise and fall of the furnace pressure will make the refractory bricks due to the gas pressure between the layers too late to balance, the pressure difference becomes large and destroyed, the furnace temperature and pressure fluctuations may lead to serious fluctuations in the furnace temperature and pressure may lead to the collapse of the entire refractory masonry.

When dealing with detachment, refractory bricks need to be built in the proper proportions to minimize the possibility of detachment. There are many reasons for detachment, which makes it more complicated to deal with. We need to find the right solution based on the actual situation and the root cause of the problem.
