Ceramic Rolls Properties

a) With extremely low thermal-expansion coefficient, therefore it has the greatly strengthened thermal
stability does not distort under high temperature, even in the oxidized atmosphere it may undergo the temperature fierce change within 1100°C environment.

b) With the fine inoxidizability, the product surface owns extremely durable properties.

c) High-purity of chemical composition, thus refrained the ingredient of the product and surface quality from pollution.

d) The extremely ceramic physical properties guaranteed the stable performance under the ambient temperature and the operating temperature environment, with small size tolerance and outstanding quality. With the reliable axle neck, the serial number and quality examination report. Our products own the traceability
