Spun cast rolls for normalizing furnace

　　







Furnace rolls are mainly used for heat treatment of plates. Its manufacturing requirements are high, and the requirements for safety, reliability and high temperature resistance are high. The material and performance of the furnace roller directly affect the operating efficiency. The quality of the furnace roller directly affects the surface quality of the product. If traditional graphite carbon sleeves and ceramic coated rollers are used, phenomena such as roller surface oxidation, furnace roller knots, and pineapple loosening are prone to occur, which will affect normal production activities. Quartz ceramic hollow roll has 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. Replacement operations can be avoided, efficiency can be increased, and product surface quality can be improved. And long service life, long-term use is not easy to wear and tear.
 
 Rolls for roller hearth slab reheat furnaces usually uses normalizing furnace, glowing furnace. Under hydrogen nitrogen protective atmosphere, furnace bottom roll temperature is about 900 degrees in heat treatment furnace, its role is to evenly and rapidly transport wide and thick plate in order to complete the heat treatment process.
