Isolite Insulating Isowool VFS

Manufacturer: Isolite Insulating

ISOWOOL VFS

Features

Non-wettable characteristic to the melting metals, high melting point, heat insulation property and durability

Slurry made of ISOWOOL BULK, inorganic binder, a tiny amount of organic binder, and water is molded and dried to make VFSs in a variety of forms such as flat plates, sleeves, cones, etc. With its non-wettable characteristic to the melting metals, high melting point, heat insulation property and durability, VFSs are used in the sections to have direct contact with the melt in aluminum molding and processing processes

Typical Applications

1. Tap-out-corn for melting aluminum
2. Riser sleeves, Hot tops
3. Combustion chambers of water boiler
4. Hot face lining of electrical furnace
5. Burner block, Peephole tile
6. Riser pipe and Skid-pipe of reheating furnace
7. Insulating cover for Continuous casting nozzle
8.High temperature gasket and packing

SLEEVE C:
Insulating pipe special for riser sleeve or riser system of special steel and non-ferrous metals.
