For refractory brick, we may not feel strange. With the progress of society, the application of refractory brick is
more and more widely. Refractory brick appear collapse phenomenon in
the actual using, so what causes it; following the Xinmi Changxing
refractory material factory is simple to give you introduced the
refractory brick collapse reason:
1, red hot refractory brick suddenly quenched with water will rupture and fall.
2,
oven heating stage , rate master is not strict, temperature rise too
fast, causing severe dehydration, masonry and damage due to expansion
and shrinkage.
3, building stove masonry to expand stay insufficient, cracked and falling temperature after expansion.
4,
the ash accumulation system, most of the metal salt corrosion of the
refractory brick, embitterment of vanadium and nickel will penetrate
into the refractory brick falling off caused by.
5 when the liquefied gas, heating, air flow ratio is undeserved, cause furnace blasting and vibration split off.
6, poor air flow furnace, flame directly flush furnace brick, the furnace brick thinning after a serious fall.
7,
the operation course lifting furnace temperature pressure to balance,
it is strictly prohibited to excessive temperature and pressure, avoid
the sharp rise in the drop, because the temperature of each layer of
brick always lags behind the furnace temperature, the more rely on the
outer temperature changes more slowly, if drastic changes in a short
time the temperature of the furnace, brick layer between refractory
brick and brick joints rupture is caused due to temperature difference
is too large to generate huge internal stress. Furnace pressure will
cause the sudden change, refractory brick
for each layer of gas pressure can't balance, pressure increasing and
destroyed, may cause the whole refractory lining of furnace temperature
fluctuation pressure serious collapse.
