What is Sillimanite Brick?

As we can know from the name, sillimanite brick is mainly made of high quality sillimanite. Commonly, manufacturers use two methods to produce this brick: high temperature sintering method and casting method.

Combining the research results of Kerui’s R&D department and market feedback, Kerui developed a tunnel kiln for mass production of sillimanite bricks. And this production method has been highly recognized by the local government and peers. Over the years, Kerui sillimanite bricks have received high praise from customers for excellent performance. At present, Kerui high alumina refractories have accumulated a good reputation in the market and achieved huge social and economic benefits.

Improvements of KERUI Sillimanite Refractory Brick

Higher Sintering Temperature

During production, the sillimanite refractory fire brick requires higher sintering temperature. Therefore, this product has more excellent properties. For example, it has better refractoriness, chemical resistance, thermal shock resistance, wear resistance, thermal stability and so on.

More Stable Performance

Due to the excellent raw materials, Kerui sillimanite bricks can still maintain stable performance in the face of severe temperature changes, acid corrosion or other working environments. Accordingly, when customers apply sillimanite bricks in kilns, this product can help customers extend the service life of their kilns.
