CUARSIL IS4 0.6 AT
Characteristics:
- Dry silica mass based on high purity microcrystalline quartzite, mixed with a special sintering agent that provides it with higher refractoriness and higher resistance against erosion, penetration and molten metal wettability..
Applicatión:
- Lining of high, low or medium frequency coreless induction furnaces melting spheroidal iron and alloyed iron at high casting temperature.
- Alloyed steel castings and, generally, any cast which requires better performance qualities than CUARSIL IS6 type mixed with boron oxide or boric acid.

Insertec Technical Data Sheet
Humidity It is guaranteed a maximum of 0.2 % of moisture at the end of the manufacturing process. When the material is going to be used, moisture content must be checked as it can change depending on the transport, storing or environmental conditions. Caracteristicas Dry silica mass based on high purity microcrystalline quartzite, mixed with a special sintering agent that gives it higher refractoriness and bigger resistance against erosion, penetration and wetting by molten metal. Application Lining of high, low and medium frequency coreless induction furnaces melting spheroidal iron or alloyed iron with high casting temperature, alloyed steel castings and generally, any cast which requires better performance qualities than the CUARSIL IS4 typ Temperature 1.700 ºC. Grain Size Distribution 0 – 4 mm Tipo de Ligante Chemical – Ceramic. Chemical Analysis Al2O3: Máx. 0,9 % - SiO2: 98 – 99 % - Fe2O3: Máx. 0,4 % Density > 2.080 Kg/m3 Installation Dry hand ramming or using specific vibration equipments for bottom and sidewalls. See instruction manual. Storage Pallets must be stored in a dry place. Once open, it must be totally consumed or, at least, cover the remaining sacks with a plastic sheet.
