Shaker Hearth Furnaces: Delivering Consistent Heat Treatment for Bulk Parts
A shaker hearth furnace is a type of continuous furnace that utilizes a vibrating hearth plate to move parts through the heating chamber.
This vibratory motion ensures parts are constantly agitated, preventing them from sticking together and promoting uniform heating. These furnaces are designed for continuous, high-volume heat treatment applications. They excel in processing large quantities of small to medium-sized parts in bulk quantities, ensuring consistent results in both batch and controlled atmosphere environments.
How Shaker Hearth Furnaces Work
The key feature of this furnace is the hearth. This is a vibrating plate made from heat-resistant steel that traverses the furnace chamber. Parts are loaded onto the hearth and as it vibrates, the parts progress through the furnace in a series of short steps. This constant movement prevents parts from resting on each other and ensures even heat distribution for uniform processing.
