Refractory kiln furniture High Temperature Resistance Alumina
Ceramic disc
1. Description
Wear-resistant alumina ceramic disc are a special aluminum-oxide
ceramic developed specifically for use as a wear resistant
surfacing material. Harder than any naturally occurring substance
except diamond, almost any surface subjected to sliding abrasive
action can be protected with alumina ceramic. For example, it is
being used to protect the metal surfaces of chute, bins, and
hoppers, vibrating feeder pans, cyclones, centrifuges, conveyors,
elbows and other equipment which is subject to severe abrasion.
Wear-resistant alumina tile are easily installed by plant
maintenance people. They are available in standard brick and tile
shapes as well as in special shapes to fit irregular contours.
Fastening the ceramic to metal or other backing material is
accomplished by using cements, by mechanical means, or by a
combination of cementing and mechanical attachment. The type of
installation will determine which of the following methods to use.
High purity alumina ceramic tray can stand 1700C at most, widely
used in furnace kilns and other applications.
2. Product Advantages
- The main material of our products is high purity quality alumina,
which cause no negative effective effect to the grinded material.
- High density and hardness, impact resistance, low loss rate, smooth
surface and no contamination to product.
- With high grinding efficiency which can reduce grinding time to
reduce energy cost and being good for environment protection.

Our general ceramic parts include, tube, rod, plate, disc, wafer,
ring, seal, bearing, valves,
pump plunger, beam, roller, shaft, screw, washer, sleeve, hunger,
spacer, holder, carrier,
insulator, scissors, knife, slitter, tweezers, tools, fixture,
clamp, chuck, nozzle, guide, frame,
lining, and grinding media, milling ball or beads.
These precision toleranced ceramic components or assemblies are
used in a wide range of
semiconductor, electronic, electrical, mechanical, chemical,
automotive, textile and the other
industrial engineering applications, due to their extreme hardness,
more resistances to wear,
heat, corrosion, high electric insulation, and low thermal
expansion.
