Loading – Horizontal Resting
Advantages :

Space Saving

Its circular design provides a much longer “heating path” in a smaller footprint compared to a long, straight-line tunnel furnace.

 Since the loading and unloading points are usually right next to each other, a single operator or robot can handle both tasks.

 Minimizes heat loss because the furnace remains closed; only the small doors open briefly for parts to enter or exit.

Unlike push-type furnaces where parts touch each other,
rotary hearths keep parts separate, allowing heat to circulate around the entire surface of each component.

Application :

Forging Industry

Heating steel billets for automotive crankshafts, axles, and connecting rods.

Heat treating circular components like turbine jet engine rings or discs.

Heating railway wheels or large industrial rims before forming.

Heating “donuts” of steel before they are rolled into large diameter seamless rings.

Process in short

Loading: Parts are placed onto the rotating hearth through the charging door, often by an automated robotic arm or a specialized charging machine.
Rotation: The hearth moves in discrete steps or a slow, continuous motion. As it rotates, the parts pass through various heating zones.
Zone Heating: The furnace is divided into pre-heating, heating, and soaking zones, each controlled by independent burners or elements to achieve a specific thermal profile.
Unloading: Once the part has travelled the required arc (usually nearly 360°), it reaches the discharge door at the desired temperature.
Transfer: The hot part is immediately moved to a forge press, a quench tank, or a cooling station.

Purpose :

Continuous Production: To provide a steady stream of heated parts for high volume manufacturing lines.
Uniform Heating: To ensure that every part—regardless of when it was loaded—receives the exact same thermal treatment.
Pre-Forge Heating: To heat billets or ingots to a plastic state (typically 1100°C to 1250°C) for shaping in a press or hammer.
