Rotary hearth furnace construction combines advantages of both continuous and chamber furnaces. Rotary furnaces ensure continuous work flow compact design that uses a minimum of floor space

Key construction features of rotary hearth furnaces

Working temperature: up to 1300°C High temperature uniformity Overpressure controlStep-less control of the hearth rotation speed Flexible operation

Work flexibility and high reliability easy service and maintenanceEconomical Low consumption of technological mediumsHigh quality parts no scale and decarburization high repeatability of processesFully automated quick loading and unloading of the loadConstruction accommodates operation in industrial conditionsSafe operationConformity with the AMS 2750 D

Main advantages
