Xin Feng Mini-Classroom---How to Manage Stainless Steel Fans During Operation?

Improve management methods and prohibit improper operation. Strictly adhere to the correct operating procedures for stainless steel fans. Even when starting under load, especially during no-load starts, loaded starts, low furnace flue gas temperatures, or low-load operation with the fan under load, extremely low furnace flue gas temperatures may prevent startup.

Motor dynamics, multiple start currents, overheating, and overload during startup can cause damage. When the furnace kettle is in operation, ensure proper use of the roller.

First, run the stainless steel fan for 10 minutes to clear dust and combustible gases from the furnace and vents. When starting the fan, the impeller will rotate, increasing motor load and risking overheating.

Strict inspection of timely maintenance and quality control for stainless steel fans is essential. Under new conditions, safety hazards in ventilation duct maintenance have been eliminated, and comprehensive maintenance has been completed.

Careful consideration is required for intake vehicle windshield power switches, lubrication and water-cooling standards of stainless steel fan rolling bearings, including damage to the sandwich layer, balance of the shaft and impeller, loosening of internal connections, conflicts, and flexibility.

To enhance impeller wear resistance, surface reinforcement components were selected. Given the presence of corrosive vapors in flue gas and its transportation at 200°C, welding of blades and damaged component surfaces is essential.

To enhance the wear resistance of stainless steel fan blades, DC welding machines, manual arc welding methods, specialized fan wear-resistant overlay welding, and wear-resistant flat welding must be performed after drying at 300-350°C for one hour.

Dust on the blade surface can be removed. Rust must be heated to 100°C. Welding should be conducted under low current and low output power conditions, with controlled working pressure, temperature, short arc, and symmetrical welding.
