Bottom Roller

The furnace hearth rollers are made of heat-resistant alloy steel hollow furnace hearth rollers of various national standard materials with a diameter ranging from Φ60mm to Φ1600mm. The materials used are also different. Suitable for annealing treatment of plain carbon pipes, oil well pipes, stainless steel pipes, etc. Especially for the production of large-diameter hearth rollers for continuous annealing production lines that require higher reliability. 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 an ideal replacement for traditional graphite carbon sleeves and ceramic coated rollers. product. It can effectively solve the problems of oxidation and nodulation, and significantly improve the surface quality of steel strips. It is not easy to wear after long-term use, and the service life is 3-5 times that of the carbon sleeve. The old roller can be used repeatedly after being reprocessed, which greatly extends the service life and reduces production costs. The operating temperature is as high as 1100℃, which is especially suitable for continuous annealing furnaces of high-grade silicon steel.
