High Alumina Ceramic Rollers

Introduction：
High temperature ceramic roller adopts high alumina micropowder and corundum as the main raw materials,which are formed by advanced special equipment and calcined by specially designed high temperature kiln furnace,and then precisely processed,which can meet the requirements of various roller kiln furnaces.
 
Features:
1.High strength.
2.Wear resistance.
3.Good corrosion resistance.
4.Low coefficient of thermal expansion. 

Application:
It can be widely used in the manufacturing of wall tile,roof tile,rustic tile thin tile,porcelain tile,polishing glazed,tableware and other ceramic products.

The physical and chemical data in the table are obtained from laboratory test samples,it is for reference only.
The maximum operating temperature of the roller is determined by the size of the roller, the distance between the supporting points, the distance between the center of the roller, the load and the load width in the kiln.
The highest temperature in the table is the recommended data under laboratory condition.The actual long time service temperature should be 30to50 ℃ lower than the highest service temperature.Special shaped roller can be customized according to customer's requirements
