Rotary Hearth Furnace
The rotary hearth furnace is designed to process and heat a wide range of materials, including metals, ceramics, and other materials. The furnace can be used for various thermal processing applications, such as annealing, hardening, tempering, and sintering.
During the processing, the material to be processed is placed on the rotating hearth and heated as it rotates. The stationary circular wall ensures that the material stays within the furnace and prevents any heat loss.
Function
It provides controlled heating and cooling cycles to achieve desired material properties.
Configuration
The furnace consists of a rotating hearth that is supported by a stationary circular wall. The wall is lined with refractory material to insulate the furnace and protect it from high temperatures.
Features
Rotary hearth furnaces typically include features such as automated loading and unloading, temperature control, and atmosphere control. They may also include features such as preheating zones, quenching systems, and cooling systems.
Temperature Range
The temperature range of a rotary hearth furnace varies depending on the materials being processed and the heating method used.
Heating Rate
The heating rate of the furnace is adjustable, with options for ramp and soak programming.
Capacity
The capacity of a rotary hearth furnace varies depending on the size and configuration of the furnace. It can range from small laboratory-scale units to large industrial-sized furnaces.
Heat Source
The furnace can be heated using a variety of heat sources, including gas, electricity, and oil.
Power Requirement
The power requirements of a rotary hearth furnace depend on the size of the furnace and the heating method used.
Atmosphere
The furnace can operate in a range of atmospheres, including air, inert gas, and reducing gas.
