company news about High-alumina refractory brick may produce net cracks

High-alumina refractory brick may produce net cracks, due to the blank in firing occurred during contraction and secondary mullite Petrochemical reaction and corundum recrystallization will lead to product surface reticulate. High alumina brick sintering is liquid phase sintering, liquid phase formation temperature and liquid phase volume, firing when the atmosphere is caused by an important factor in high alumina refractory brick surface network cracks.
