company news about High-alumina refractory brick products

High-alumina refractory brick products generate more surface network cracks in the brick yard brick surface cracks.It can be inferred that when the kiln excess air coefficient, or produce a reducing atmosphere due to smallcracks between the blocks, CO easy to stay in these places, so that the products of Fe2O3 is reduced to FeO;channel-oriented brick surface, relatively smooth airflow , so the impact will not be affected by changes in the atmosphere, there is no network of cracks generation.
