Magnesia hercynite (chrome free) brick

This brick has won 4 national invention patents. It is mainly used in burning zone of large and medium scale dry process cement rotary kiln. It has the advantages of chromium free and environmental protection, very good in thermal shock resistance, easy to forming the coating layer, excellent erosion resistance, low thermal expansion and thermal conductivity, good structural flexibility. In practical application, the brick service life is more than 12 months, fast to form the coating layer in burning zone with uniform and stable thickness, low temperature of kiln shell, small heat loss.
