Plug (high aluminum) brick
Plug (high aluminum) brick
Product advantages: high refractoriness, good chipping resistance and strong corrosion resistance.
product description
Plug (high aluminum) bricks are also common in high-alumina refractory brick products. They are used to prevent the lining of ring-shaped bricks from sinking, falling off or even falling due to loosening during long-term rotation, and the cylinder is concentric The inner lining of the circular column is divided into several parts with the same shape and size, and each part can be a fan-shaped refractory brick.
Plug (high aluminum) bricks are mainly used to build the lining of rotary kilns. Accept custom plug (high aluminum) bricks, you can provide us with the size of the refractory bricks you need, and we will customize them for you.
