Supply dumping furnace corundum sand 3-5mm iron ditch roll material with a sharp stone Group corundum of sand

Corundum furnace supply dump sand on the roll 3-5mm, iron ditch materials with a sharp stone Group corundum of sand sharp stone corundum is sharp stone company to meet actual usage refractory industry, universities and research institutes supported by the use of modern novel Unique 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. Refractory corundum physical and chemical indicators: use standard chemical composition (%) magnetic content (%) Al2O3 Fe2O3 SiO2 TiO2 refractories segment sand 0-1mm 1-3mm 3-5mm 5-8mm 8-12mm ≥94.5 ≤0.3 ≤ 1.5 ≤3.0 - 0-3mm 0-5mm 0-10mm 0-25mm ≥94.5 ≤0.3 ≤1.5 ≤3.0 - powder 180 # -0 240 # -0 320 # -0 ≥93.5 ≤0.5 ≤1.5 ≤3.5 - physical indicators color density Mohs hardness crystalline melting point line refractoriness brown 3.90g / cm3 9.0 2050 ℃ 1900 ℃ crystal Rui Shi tripartite group can provide a particle size of F12-F220, of sand: 0-1mm, 1-3mm, 3-5mm, 5- 8mm, 8-12mm, powder: 180 # -0,240 # -0,320 # -0, size composition referring to the current GB / FEPA / ISO / JIS and ANSI standard screening, also supply other specifications according to customer requirements .
