Alumina Ceramic Disc Refractory Kiln Furniture Wear Resistant High Density
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.
