High silica fiberglass refractory filter,cup style

High silicafiberglasssrefractory filter cup1.NINGXIN Fiber Filters are made from high temperature resistant glass fiber. These filters will effectively remove non-metallic elements in the melt resulting in improved quality and yield of castings.2.Our main raw materials is high silica oxygen nets cloth, supplied by ShanXi HuaTe glassfiber limited company, which is designated to produce the high silica oxygen glass products for Chinese aerospace ,the silica (SiO2) contain not less than 97%, production adopting Na2O - B2O2 - SiO2,its fiber capacity is 3 to 5 times over E glass.The product is examined by Beijing glass research institutes and shows it can bear 160 seconds under 3000°C.3.Thefiberglass meshhas high strength both under high and normal temperature circumstance, high-flush resistance, low emit gases and good chemistry stability.The strainer is applied in metal casting for filtration purification, can make its scrap rate reduce of 50-60%. Our products is widely used in grey casting iron, ball iron, aluminum alloy, copper alloy and cast steel products etc.. 4.Technical DataTypeWork temperature(°C)Softening rate(°C)Lasting working timeThe tensile strength of normal atmospheric temperature (kg/4)Emit the quantity of gas (cm3/g)XR21400-14501750≤10 minutes ≥8 ≤60XR31600-16201750≤15 minutes≥16≤60Thickness: 0.35mmOpen Area: 50-60%Hole size: 1.5x1.5mm, 2.0x2.0mm, 2.5x2.5mmSizes Available: Can be produced according to customers requirements5.direction for use1).Placement:Filters can be cut to any size using a pair of scissors.Filter may be placed at the intersection between the pouring cup and runner. Historically, the best filtration results have been achieved by placing the filter as close to the ingate as possible.2). Sectional Area Sectional Area of filter = Sectional Area without filter / (a x b)a: Filter open area: 50-60%b: Filtration efficiency: 60-80%So the sectional area with the filter is normally about 2-3 times that without a filter.6.Package:Packed in cartons or according to customer requirements.
