RS棕剛玉是銳石公司為適應耐火行業實際使用情況，經各高校及研究院支持，采用現代新型獨特冶煉、加工工藝技術，自主開發生
產的特有拳頭產品。
RS棕剛玉具有純度高，結晶好，流動性強，線膨脹系數低，耐腐蝕的特點。經數十家耐火生產企業實踐驗證，該產品在應用過程中
具有不起爆、不粉化、不開裂的特點。尤其是其遠高于傳統棕剛玉的性價比，更使之成為棕剛玉質耐火材料的**骨料和填料。
In order to meet the demands of the refractory industry, We independently develop and produce RS Brown Fused Alumina which is adopted by modern
unique technology of smelting and processing under the universities and research institutes' support.
RS Brown Fused Alumina is characterized by high purity, good crystal, strong fluidity, low coefficient of linear expansion,good corrosion-resistance and
so on. After practical tests by dozens of refractory manufacturers, RS Brown Fused Alumina can' t burst, pulverise and craze in the using course. In
particular, its performance-cost ratio is much higher than traditional Brown Fused Alumina, making RS Brown Fused Alumina become the best
aggregate and padding of brown fused alumina refractory materials.
