Wearable Ceramics
|
|
The corporation can
supply series of wearable ceramic products such as general wearable
gaskets, resistance to thermal shock resistance gaskets, lining
boards, lining bricks, wearable ceramic balls, ceramic tubes
and bars. The products possess good characteristics of high
hardness, wear resistance, erosion resistance and high temperature
resistance. Being as wear and erosion resistant lining boards
for milling equipment，transporting equipment of high wearable
medium, and high temperature erosion resistance equipment, They
are widely used in the industries of building materials, thermal
electricity, chemical engineering, coal , metallurgy and medicine，etc.
