High Alumina Ceramic Insulator High Density Wear Resistant Flat Shaped Plate

High Alumina Ceramic Insulator High Density Wear Resistant Flat Shaped Plate


1.Description

Aluminum Oxide Ceramic Sheet / Alumina Wear Ceramic Plate is sintered on high temperature of more than 1530℃, with high-purity ultra-fine alumina powder as raw material according to optimized formulation design. They are usually installed uopn the wear areas of some material conveying equipments, coal preparation equipments and so on to be used as the material contact surface to bear the following abrasion and impact.

2.Features

1.High hardness

Its Rockwell hardness HRA80-90, hardness second only to diamond, and the wear-resistant is far more than wear-resistant steel and stainless steel.

2.Excellent wear resistance

Equivalent to 266 times than the manganese steel and 171.5 times of the high chromium cast iron. In the same conditions,it can extend the service life at least above ten times.

3.Light weight

The weight is only half of steels, so can greatly reduce the equipment load.

4.Corrosion resistance

High alumina ceramics are inorganic oxides with extremely stable molecular structure and no electrochemical corrosion, thus they can resist erosion of acid, alkali, salt solutions and organic Solvents.

5.Stability of heat temperature

Working temperature of high alumina ceramics can be as high as 1600℃.

6.Smooth surface

High alumina ceramics have the properties of smooth and adhesion, the roughness is only 1/6 that of steel pipes thus less flow Resistance.

3.Application

Aluminum Oxide Ceramic Sheet / Alumina Wear Ceramic Plate is widely used for serious abrasive environments, such as chute liners, cyclone liners, conveyor skirt liners, processing piping liners, hopper or silo liners, screen equipment liners in the industries including ,but not limited to:

♦ Coal Preparation Plants ♦ Coal Fired Power Stations
♦ Mineral Processing Plants ♦ Cement Plants
♦ Chemical Plants ♦ Steel & Iron Plants
♦ Railway Stations ♦ Ports
