SUPER HIGH TEMPERATURE CERAMIC ROLLER OF S-6000 (GF98)

The refractorinedd of S-600 super high temperature roller is up to 1800^oC, and the working temperature is up to 1400^oC. Because of the excellencies of the low thermal expansion, high bending strength, perfect toughness and optimized microsturcture, S-600 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.

SUPER HIGH TEMPERATURE CERAMIC ROLLER OF S-5000 (GF95)

This series roller has high density, low modulus of elasticity, heavy load in high temperature, especially fit for wide body and large output kiln and producing heavy load products, like roof tiles, large dimension floor tiles.

HIGH TEMPERATURE CERAMIC ROLLER OF S-4000 (DF95)

With the working temperature of 1300 degree and excellencies of high bulk density and bending strength, no bending and crack, as well as low wearing loss, S-4000 series roller is the most popular roller and enjoyed the largest sales in the world, especially suitable for producing porcelain tiles and rustic tiles.
