The performance of the furnace roller is:
1. The quality of the rollers of the silicon steel continuous annealing furnace is one of the main factors affecting the operation rate and product surface quality. Traditional graphite carbon sleeves and ceramic coated rollers are prone to roller surface oxidation, roller nodulation, loosening and peeling. , affecting normal production.
2. Quartz ceramic hollow rollers have the characteristics of high strength, high temperature resistance, small thermal expansion, good chemical stability, stable high temperature performance, no deformation, smooth and delicate surface, and good wear resistance. They are the superior features of traditional graphite carbon sleeves and ceramic coated rollers. Ideal replacement product.It can effectively solve the problems of oxidation and nodulation, avoid frequent replacement operations, improve operating efficiency, and significantly improve the surface quality of the steel strip.
3. It is not easy to wear after long-term use, and the service life is 3-5 times that of the carbon sleeve. The used old roller can be used repeatedly after being reprocessed, which greatly extends the service life and reduces production costs.
4. The operating temperature is as high as 1100°C, especially suitable for continuous annealing furnaces of high-grade silicon steel.
5. Adopting the company's original fine quartz ceramic manufacturing technology that won the third prize of the National Science and Technology Progress Award, we have developed quartz ceramic furnace bottom rollers for nearly ten years. The performance of the products has reached the level of similar foreign products. After many domestic Used by a well-known silicon steel manufacturer, it achieves the same effect as the imported products used in the same furnace.
6. It can provide designers and users with structurally reasonable design process parameters of hearth rollers to ensure the assembly quality and use effect of the hearth rollers.
