White corundum brick • production process
White corundum hardness is slightly higher than brown corundum,
toughness is slightly lower, high purity, good self-sharpening,
strong grinding ability, low calorific value, high efficiency, acid
and alkali corrosion resistance, high temperature resistance and
thermal stability.Made of white corundum sand abrasive tools,
suitable for grinding high carbon steel, high speed steel and
stainless steel and other fine grain abrasives, white corundum can
also be used for precision casting and senior refractory materials.
White corundum brick has the characteristics of high
refractoriness, good thermal shock stability, high high temperature
strength, excellent corrosion resistance, strong slag resistance,
small expansion coefficient, low creep property, anti-peeling and
so on. It is suitable for the use of high temperature kiln under
various atmosphere conditions.High quality high purity corundum
brick is widely used in high temperature sintering of zirconia
ceramics, fluorescent materials, electronic ceramics, magnetic
materials, ceramic powders, gasifier in petrochemical industry,
second-stage reformer for synthetic ammonia, carbon black reaction
furnace and high temperature kiln furnace in glass industry,
etc.The appearance size, physical and chemical indexes and service
life of the products have reached or exceeded the level of similar
products at home and abroad.
