Supply dumping roll furnace corundum ramming mixes with sand 0-1mm of sand corundum corundum powder

Corundum furnace supply dump sand on the roll 0-1mm, ramming mixes with corundum of sand, corundum powder Rui Shi Rui Shi company is corundum refractory industry to adapt to the actual usage, supported by universities and research institutes, the use of unique modern new smelting, processing technology, independent development and production of unique high-quality products. Rui Shi product has high purity, good crystalline liquidity, low coefficient of linear expansion, corrosion-resistant characteristics. Dozens of refractory manufacturers have proven that the product has not detonate in the application process, not powder, not crack features. In particular, its cost-effective than traditional corundum, but making the best corundum refractory aggregate and fillers.
