The Use and Maintenance of Convection Fans in Forced Convection Tempering Units

When the temperature inside the tempering furnace exceeds 300 degrees, the convection fan inside the furnace should not be stopped for a long time to avoid deformation of the fan impeller.

The correct frequency range for the use of the convection fan during the tempering process is between 30 and 60. When operating in zone 30, the bearing of the fan impeller has poor heat dissipation, which affects its service life. Add high-temperature resistant grease to the bearings every 30 days of use for the convection fan of the tempering furnace.
