Ceramic Foundry Sand with the high quality bauxite as the raw material, blowing into the ball after remelting smelting, is a new type of steel casting foundry sand.It s characteristic as high temperature resistant,small amount of thermal expansion, easy collapse, good renewable performance,good casting properties, received the recognition from the cast made experts domestic and overseas. Widely used in all kinds of casting method,sand casting, special casting( casting, solid type, evaporative pattern casting, ladle flow guiding sand and so on ).Also used for shot peening, low expansion of high-temperature coated sand producing. 200mesh-270mesh used for evanescent mode coating producing. Adding 10-35% can effectively increase the air permeability, and suitable for useing all kinds of casting binder.It has been used by numerous domestic and international cast iron and nonferrous metal casting production factories. Ceramic Foundry Sand Technical Specification: 2.GRain Shape: Ball 3.Colour: Brownish black 4.Density: 1.95-2.05 ( g/cm3) 5.Refractory temperature:1850 6.Thermal expansion Rate:0.13% 7.Size: 10-20mesh 20-30mesh 30-40mesh 40-70mesh 100-140mesh 170mesh
Brown fused alumina melt film precision casting sand is based on the production of the brown fused alumina and with special technology, it is produced by the careful organization of the researchers. The quality has reached the advanced level of similar foreign products through laboratory tests and production in practice of dozens of casting enterprises. And some performances of it can be adjusted or showcased according to the customers requirement. The precision casting sand with high refractoriness, low thermal expansion coefficient, good thermal stability, strong air permeability, high intensity, easy to shell, high casting finish.It can substitute Zirconia sand (powder) its price is only half of zirconia sand (powder), and the recovery ratio is high as well. It can be mainly applied to the melt films and silicasol technology of jewelry, handicrafts, stainless steel products, watches, glasses, aluminum die casting industries, and can be processed in line with the demands of the clients.
