Tempering Furnace Fan

Danyang Dingfeng Industrial Furnace Co., Ltd. is one of the most reliable manufacturers and suppliers of tempering furnace fan in China. If you're going to wholesale durable tempering furnace fan made in China, welcome to get pricelist from our factory. All customized products are with high quality and low price.

You need this to move the air around inside a tempering furnace. Without it, the top of the furnace gets hot and the bottom stays cool. The tempering furnace fan fixes that. It circulates hot air so every part gets the same temperature.

Working Principle

 

During tempering, the fan runs continuously. It pulls air from the chamber, pushes it across the heating elements, and blows it around the workpieces. Forced convection. No stagnant zones.

 

The fan runs hot – really hot. The motor sits outside the furnace, connected by a long shaft. The shaft goes through the furnace wall. Seals keep the heat from leaking out.

• Temperature range. These tempering furnace fans run from 200°C up to 700°C. The impeller and shaft are made from heat resistant alloys. Standard steel would warp in a day.
• Seals matter. The seal where the shaft goes through the wall is critical. If it leaks, hot air blows out into the motor bearings. Bearings cook. Grease dries up. Fan seizes. Good seals save motors.
• Even airflow. The impeller design isn't random. We spend time on the fluid dynamics. A well designed fan moves air evenly across the whole chamber – not just a blast straight down.
• Thermal shock resistance. The fan starts and stops. It heats up, it cools down. The alloy has to handle that without cracking. Cheap fans crack. I've seen impellers come apart after a few hundred cycles.
• Speed control. You can add a variable frequency drive. Run the tempering furnace fan fast during heat up, slower during soak. Matches the airflow to what the parts need.

Heat treatment furnaces. Tempering furnaces, annealing furnaces, aging furnaces, stress relief furnaces. Any furnace that needs even temperature.

Industrial ovens. Drying, curing, baking.

Metal processing. Steel heat treatment, aluminum alloy heat treatment. Precision machining shops use these on their tempering furnaces.

Auto and aerospace. Gears, bearings, high strength alloys. These customers run tight tolerances. Even temperature is not optional.
