CUARSIL IS6 1 PAN

CHECK IN AND CONSULT THE PRICE

Availability: In stock

CHARACTERISTICS:


Dry silica mass based on high purity microcrystalline quartzite, mixed with either Boron Oxide (B203) -AN as a sintering agent.


It differs from CUARSIL IS4, because its aggregate composition and grain size distribution have been optimised.


Therefore, a better material with higher density and lower porosity has been achieved.




APPLICATION:


- Lining of high, medium and low frequency coreless induction furnaces for nodular or alloyed melting with high temperature casting, and, in general, those linings that require better performance qualities than CUARSIL IS4 with Boron Oxide

Installation Dry hand ramming or using specific vibration equipments for bottom and sidewalls. See instructions 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. Maximum lifetime: 12 months.
Packing Paper Sac of 25 kg. On Pallet of 1200 kg
Drying and Heating Depending on furnace’s capacity, heat up to working temperature at a rate of 100-180ºC/h. (with Boron Oxide as a sintering agent) or at 60-120ºC/h. (with Boric Acid). Sintering should be done at 30-50ºC over the working temperature, keeping this temperatu
Water Required Casting and Vibrating It is guaranteed a maximum of 0.2% of moisture on finishing the manufacturing process. When supplied with boric acid, take into account the water released on heating at 140 ºC (approx. 44% of the acid weight). When the material is going to be used moistur
