WALKING BEAM FURNACES

In a walking beam furnace, reheating occurs as the steel slabs or billets move through multiple temperature zones (such as preheating, heating, and soaking zones). 

Each zone is equipped with burners or heating elements strategically placed to evenly distribute heat. As the material advances step by step on the lifting and moving beams, it remains exposed to controlled high temperatures that gradually bring it up to the desired level.

Preheating Zone: The material first enters a lower-temperature area, preparing it for the intense heat that follows.

Lifting and Moving: A second set of beams rises to lift the material, then moves it forward one step.

Soaking Zone: The final section maintains the target temperature for a set period, allowing internal heat equalization and consistency.

Throughout this process, the furnace’s insulation and design help minimize heat loss, while the walking beam mechanism reduces mechanical friction and ensures uniform exposure.

By carefully regulating temperature in each zone, the furnace delivers a consistent, high-quality reheating for subsequent processes like rolling or forging.
