What Are Trolley Type Furnaces?

1.1 Defining Trolley Type Furnaces

A trolley type furnace, also known as a bogie hearth furnace, is a specialized industrial furnace characterized by its movable platform or trolley. This feature enables the furnace to accommodate large or heavy workloads for processes such as annealing, tempering, and stress relieving. Trolley type furnaces are designed to provide precise control over temperature and atmosphere, making them invaluable in applications where uniform heat treatment is crucial.

1.2 How Do Trolley Type Furnaces Operate?

Trolley type furnaces operate by placing the material or workload onto a trolley, which is then moved into the furnace chamber. Once inside, the furnace applies heat through various heating elements, such as electrical resistance coils or gas burners. The furnace’s control system regulates temperature, ensuring the material undergoes the desired heat treatment process. The mobility of the trolley allows for flexibility in loading and unloading, making these furnaces ideal for batch processing.
