Installation notes

  1. 1Clean furnace shell and apply one coat of release agent before ramming
  2. 2Ram in 50–75 mm layers using the correct pattern (spiral from bottom up)
  3. 3Each layer must be uniformly compacted, check with density gauge if available
  4. 4For induction furnaces: sinter with a gradual heat-up using scrap metal charge
  5. 5First heat: fill with metal charge, heat slowly to operating temperature, do not tap
  6. 6Typical sintering cycle: 4–8 hrs at full power to form a glassy bonded shell
