Production scale top hat furnace maintenance

No one wants expensive surprises and unhappy customers!  Help prevent unplanned production downtime by following these guidelines for your Deltech production scale top hat furnace.

Every month

  1. Inspect the interior of the top hat furnace for cracking and/or pin failures.  Replace pins as needed.  Contact Deltech if any large fissures develop or if you discover sagging insulation.
  2. Inspect the kiln car and bottom mating refractory.  Corner and bottom patch kits can be used to eliminate damaged refractory where light can leak out of the furnace.

Every year

  1. Replace the thermocouples. Thermocouples are subject to aging and as a result will indicate a temperature lower than the actual furnace temperature.
  2. Inspect the top hat lifting mechanism.  This includes, but is not limited to, fraying of the aircraft cables, and any cracking on the bearings and eyebolts.  Lock out the system  to keep operators safe and contact Deltech for replacement if any damage is found.

Every decade

  1. Full refractory reline.
  2. Replacement of aircraft cables.

As needed

  1. Heating Elements should be replaced when they fail.  If element failure is suspected, cool the furnace down prior to performing any testing.  Heating elements normally last between one and five years under standard operating conditions.
  2. Inspect element hardware for wear and tear such as braid fraying and cracking in the ceramic holders.
  3. Hearth plates are consumables and may need periodic replacement.
