Alumina Ceramic Bricks
Description
Technical Parameters
Introduce:
There are all kinds of shapes for instance square shape, rectangle shape, trapezoid and some special shape. It is the ideal wear-resistant materials for wear resistant grinding equipment such as oil, chemical, mine, steel and electricity industry. It has advantages of various types, high hardness(Rockwell hardness is HRA80-90), excellent wear resistance, impact resistance, corrosion resistance, good heat resistance and light weight. It can save the maintain cost, extend the life of machines.
Product features
1.High hardness
The hardness of rockwell is hRA80-90, which is second only to diamond and far more than wear-resistant steel and stainless steel.
2.Excellent wear resistance
Wear resistance is 266 times that of manganese steel and 171.5 times that of high-chromium cast iron.According to our customer tracking survey over the past ten years, the service life of the equipment can be extended at least ten times under the same working condition.
3.Light weight
Its density is 3.5g/cm3, only half that of steel, which can greatly reduce equipment load.
