It cas save 30% by replacing rollers at high temperature 

The series G98 rollers manufactured with the most advanced and newest formulas and processes, has super strong thermal shock resistance, higher bending strength and heavy load in high temperature, especially fit for super wide body and large output kiln to produce big slab, sintered stone ,table-ware and water permeable brick. The maximum length of the series rollers can be produced to 5200MM. 

How to use the roller affects not only the service life of the rollers but also smooth work of the kiln. Generally, we select the type of roller depending on the maximum firing temperature and load of the rollers. Meanwhile, the rotate speed, span of roller and atmosphere in the kiln are also important factors for us to consider,as well as the factors of the gas, molten materials and thermal shock, Considering the factors mentioned above, our suggestions are as follows:

1. Before used, the new rollers should be placed on the kiln for drying at least 24 hours (60 80℃)

2, Rollers with coating should be placed on the kiln for drying at least 72 hours.

3.Please fast and quickly rotate the rollers when replacing them.

4. The roller taken from the middle and high temperature area should be avoided to contact the cooling items but placed on the bracket with asbestos pad. Rotate it continously until it cools down to belaw 600℃

5. The small area of glaze droplets on the surface of rollers can affect their thermal shock resistance, sothey should be cleaned at fixed period.

6. Unqualified raw materials may erode rollers, which should be used carefully.

7. Keep the exhausting fan on and roller rotating after shtting down of kiln, turn off the other fans and prevent cold air coming, After 24hours, increase the fan speed and take out the roller when the temperature in the kiln is 500℃ or below.

8. Avoid using the roller in the alkali atmosphere and the corrosion of alkali materials in order to prolong the service life of rollers.
