Heat Resistant Furnace Roll

The furnace roll is one of the most important parts of a continuous annealing
furnace, and its working condition is the decisive factor in whether the
annealing furnace can carry out normal production. The furnace roll table of a
continuous annealing furnace is the mechanical equipment that makes the furnace
charge pass through the furnace, and it conveys the furnace charge to complete
the annealing process operation, so as to realize the mechanization of
production operation and the continuity of the process flow.
Performance:
1. The quality of furnace bottom roll of silicon steel continuous annealing
furnace is one of the main factors affecting the operation rate and product
surface quality. The traditional graphite carbon sleeve and ceramic coating
roll are prone to roll surface oxidation, furnace roll nodulation, looseness,
and spalling, which affect the normal production.
2. Quartz ceramic hollow roller has the characteristics of high strength, high-
temperature resistance, small thermal expansion, good chemical stability,
stable high-temperature performance, no deformation, smooth and fine surface,
and good wear resistance. It is an ideal substitute for traditional graphite
carbon sleeves and ceramic coated rollers. It can effectively solve the
problems of oxidation and nodulation, avoid frequent replacement, improve
operation efficiency and significantly improve the surface quality of steel
strips.
3. The long-term use is not easy to wear, which is 3-5 times the service life
of the carbon sleeve, and the used old roller can be reused after reprocessing,
which greatly prolongs the service life and reduces the production cost.
4. The service temperature is up to 1100 ℃, especially suitable for continuous
annealing furnaces of high-grade silicon steel.
5. It can provide the design process parameters of furnace roll with the
reasonable structure for the design and use units, and ensure the assembly
quality and use of the effect of furnace bottom roller.
