Furance Fan Blade

What are furnace fan blades?

1. Core Definition: Furnace fan blades are key airflow-guiding components installed inside heat treatment furnaces, responsible for evenly distributing hot or cold air to every corner of the furnace chamber, achieving rapid and uniform temperature distribution.
2. Working Principle: The aerodynamic design of the blades creates a strong and controlled air flow as they rotate, avoiding localized hot or cold spots and thus improving heat treatment quality.
3. Key Features: High-temperature corrosion resistance, high structural strength, and a high surface finish ensure stable operation in extreme environments ranging from hundreds to thousands of degrees Celsius.
4. Company Advantages: Wuxi Junteng Fanghu Alloy Casting Co., Ltd. utilizes lost-wax casting technology to ensure flawless blade surfaces and precise dimensions, meeting stringent aerodynamic and mechanical requirements.
How do furnace fan blades impact heating uniformity and cooling efficiency during heat treatment processes?

1. Improving Heating Uniformity

Through precise airflow distribution, the blades quickly eliminate temperature gradients within the furnace chamber, preventing the formation of "hot spots." A uniform heat field ensures uniform heating of the workpiece throughout the entire heat treatment process, significantly reducing deformation and internal stress.
2. Accelerated Thermal Cycle

Efficient airflow facilitates rapid heat transfer, shortening the heating time. Similarly, heat is removed more quickly during the cooling phase, shortening the overall process cycle.
This directly leads to increased production capacity and reduced energy costs.
3. Reduced Energy Consumption

Because of improved heat utilization, the furnace does not need to operate at high power for extended periods, resulting in significant energy savings.
FH blades maintain low resistance even at extreme temperatures, further reducing fan power consumption.
4. Company Technical Support

FH blades undergo dynamic balancing tests to ensure minimal vibration during operation, extending equipment life and reducing maintenance downtime.
What are the main materials used for Wuxi Junteng Fanghu Alloy Casting Co., Ltd.'s furnace fan blades?

1. High-temperature alloy steel: High-temperature alloy steel containing elements such as nickel, chromium, and molybdenum offers excellent oxidation and creep resistance, maintaining strength at operating temperatures above 1100°C.

2. Specialty Heat-Resistant Cast Iron: For certain low- and medium-temperature furnace types, we use heat-resistant cast iron containing graphite or silicon carbide to enhance thermal shock resistance.
3. Customized Alloy Formula: FH's engineering team can provide customized alloy formulas based on the customer's maximum operating temperature, corrosive media, and operating environment, achieving the optimal "material-process-performance" combination.
