| 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 ºC lower than the highest service temperature.Special shaped roller can be customized according to customer's requirements | ||||
