Product Description


We manufacture various high-quality refractory products according to the clients' needs , and to ensure the stability and accountability of the quality


Refractory for Cement Rotary Kiln

The environments of transition zone, burning zone and cooling zone in cement rotary kiln are severe dueto high temperature from burning clinker and erosion of K,Na,Cl,S. The upsize of rotary kiln and usage inwaste disposal make the condition of using refractories even harsher. Yotai group developed MgO-Cr2O3series, MgO- AlO Spinel series and nonchrome series bricks for cement rotary kiln, which haveachieved remarkable results. We occupy top shares in Japan refractory market, and have expandedgreatly in China market as well.
