The refractoriness of S-6000 super high temperature roller is up to 1800℃, and the working temperature is up to 1400℃. Because of the excellencies of the low thermal expansion, high bending strength, perfect toughness and optimized microstructure, Jin Gang S-6000 super high temperature roller is very outstanding in thermal shock resistance. This series roller is the leading hi-tech products in the market, and the best choice for the kilns in producing the large dimension tiles and table-ware.

Notice：
The data above are verified from testing samples in the laboratory, for reference only in practical use.
The highest working temperature of the roller is determined by specification and size, distance of sustaining point, central distance, load and loading breadth in the kilns.
The Max. working temperature is commendatory. The practical working temperature is lower than the Max. working temperature by 30~50℃.
