Description

Phosphate composite brick technical field The invention relates to a phosphate composite brick, which is especially suitable for building a rotary kiln. Background technique The existing phosphate bricks lining the rotary kiln are of two-layer structure. The outer layer near the kiln skin is made of lightweight heat-insulating bricks, and the inner layer is made of phosphate bricks depending on the material. Lightweight insulation bricks and phosphate bricks are separate. On the one hand, it is difficult to build masonry, on the other hand, it is easy to loosen. With the thinning of the phosphate layer, it is easy to cause collapse accidents in the kiln. The service life of the refractory lining of the rotary kiln is within one year. Invention content: In order to overcome the disadvantages of the prior art, the invention provides a phosphate composite brick with a service life of more than two years. The technical scheme adopted by the present invention to solve its...
