RS棕刚玉是锐石公司为适应耐火行业实际使用情况，经各高校及研究院支持，采用现代新型独特冶炼、加工工艺技术，自主开发生
产的特有拳头产品。
RS棕刚玉具有纯度高，结晶好，流动性强，线膨胀系数低，耐腐蚀的特点。经数十家耐火生产企业实践验证，该产品在应用过程中
具有不起爆、不粉化、不开裂的特点。尤其是其远高于传统棕刚玉的性价比，更使之成为棕刚玉质耐火材料的**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.
