Process
introduction:
It takes super bauxite as the main material
and applies the electric arc furnace of over
2200 After
purification, trash extraction, rime, classification,
shattering, preparation by magnetic separation,
and fiber classification, the products of
various granule sizes are made.
Product performance:
High hardness, strong intensity, shock resistance,
high temperature resistance, anti-oxidation,
anti-corruption, and little distortion
Usage:
use to grind, spray sand, skive and polish
ceramics rosin. Also widely used as super
fire-retardant material of antiskid wearable
racetrack, high temperature resistant plating
layer and the ovens used in metallurgy and
chemical industry.
