Vertical Side-Loading Heat Treatment Furnace for Large Rotors and Shafts

Heat treating massive components like turbine rotors, generator shafts, and large rolls demands a furnace solution built for scale, precision, and reliability. Standard furnaces often fall short, struggling with temperature uniformity and safe loading of heavy, high-value parts. The Vertical Side-Loading Heat Treatment Furnace is a purpose-engineered solution that overcomes these challenges, offering unmatched control for the most critical large-part heat treatment processes.

Overcoming the Challenges of Large-Part Heat Treatment

Why is a specialized furnace necessary? Traditional methods can lead to:

• Temperature Gradients: Inconsistent heating across a large rotor can cause distortion and inconsistent material properties.

• Loading Difficulties: Overhead cranes for pit furnaces pose safety and alignment risks.

• High Energy Costs: Inefficient heating systems lead to excessive fuel consumption and operational expense.

Our vertical furnace is designed from the ground up to eliminate these issues, ensuring your rotors achieve optimal metallurgical properties with maximum efficiency and safety.

Key Features of Our Vertical Heat Treatment Furnace

1. Unique Split Body & Side-Loading Design

The innovative two semi-circular body design is a game-changer. Instead of lowering the part from above, the entire furnace shell moves horizontally, allowing the rotor to be loaded from the side. This simplifies the process, enhances operator safety, and reduces the risk of damaging critical components.

2. Precision Multi-Zone Temperature Control

Achieving a uniform temperature over a 16-meter height is critical. This furnace is divided into eight independent temperature control zones along its height. Each zone features its own thermocouples and burner controls, managed by a sophisticated PID + PLC control system to maintain an accuracy of ≤ ±1°C. This guarantees that every section of your rotor is heated consistently.

3. High-Efficiency, Low-NOx Combustion System

Equipped with 16 high-speed, low-NOx burners, the furnace utilizes advanced pulse combustion technology. The system switches between high and low fire modes based on real-time temperature demands, optimizing the air-fuel ratio for significant fuel savings and reduced emissions without compromising performance.

4. Robust Construction for Heavy-Duty Use

Built to handle the most demanding environments, the furnace features:

• Heavy-Duty Steel Structure: Supports the massive framework reliably.

• Full Fiber Lining: 300mm thick ceramic fiber modules provide superior insulation, reducing heat loss and cycling times.

• High-Capacity Furnace Platform: Designed to support loads up to 300 tons, ensuring stable operation.
