Check whether the furnace heating elements show grounding fault and the heating elements work properly
The chains and bearings of the furnace must have effective lubrication
Clean dust from the electrical cabinet and inverter cooling ducts
Check the tempering blower coupling for concentricity. Check the blower blades for deformation and cracks
Replace the circulating cooling water in the convection furnace to ensure that the water quality meets the standard
Check if the heating wire terminals and terminals in the heating electrical cabinet become loose
Yearly Inspection should include:
Oil in all reducers of the tempering furnace must be changed
All drive bearings of the furnace must be purged and re-oiled
The motor bearing of the tempering blower must be purged and re-oiled
The high-temperature convection blower must be replenished with oil as required
Check whether the power supply system and grounding resistance value of the furnace meet the requirements
Check the level of the roller conveyor of the tempering furnace with a flatness gauge
Clean the inside of the air duct system and chiller with a high-pressure water gun
