CDQ sloping flue column brick is a decisive position, in which the stability of the refractory bricks structure is the important topic on CDQ technology in the structure of CDQ slot.

The sloping flue column brick is a position with strict request on mechanical strength, thermal shock ability, and technique. The column structure is compact, so it is highly request on the stability of the structure design and the quality of refractory brick. NSEC adapts Finite Element Methods (FEM) which can analyze the best structure on CDQ. This method has a lot of achievements for using several years. As well as, our company adapts this method on CDQ equipment.

The other aspect is on the material. There is no suited refractory brick for sloping flue column in Chinese CDQ for a long time, so it comes out a phenomenon that is the sloping flue column brick shedding. The reason for this phenomenon is that the choice on the material of refractory brick and fireclay. Our company does a deep research on the above mentioned brick shedding phenomenon, and transfers the refractory brick’s formulation which has using achievement in NSEC to China refractory brick factory. And the fireclay which we use is made by Japan.

How to extend the service life of sloping flue column brick is a question for CDQ in China. And our company has solved it depending on our technology. We indeed have the capability to provide the owners with the CDQ equipment with using comfortably and working continuously.
