Perlite is porous, environmentally clean material of mineral origin, which provides the temperature insulation of materials (working temperature of perlite is from -200 0Ñ to +845 0Ñ). More over perlite not only provides insulation but also make steel top-good quality.
Application of perlite in metallurgy
Why perlit is better
- high heat insulation properties
- noncombustible
- diminishing development of defects of shrink origin at smelting of metal
- simple in the use
- does not make shrink and not warped
- does not retain moisture
- cheap
