  9. 9. 9 TEIDE REFRACTORY SOLUTIONS 2011Concrete dome
  10. 10. 10 TEIDE REFRACTORY SOLUTIONS 2011CONCRETE DOME: - For quick installations or repairs in 2-3 weeks. - Ceramic anchors on stock. - Average density 1,5 Kg/dm3.
  11. 11. 11 TEIDE REFRACTORY SOLUTIONS 2011Pressed suspended flat dome
  12. 12. 12 TEIDE REFRACTORY SOLUTIONS 2011PRESSED SUSPENDED DOME: - Best cost/quality ratio. - Better traction/flexion than concrete dome. - Density average 1 Kg/dm3. - Slow shut down and start firing required (1-2 weeks).
  13. 13. 13 TEIDE REFRACTORY SOLUTIONS 2011Insulating flat dome
  14. 14. 14 TEIDE REFRACTORY SOLUTIONS 2011INSULATING FLAT DOME: - Start/Stop of firing in 48-72 hours. - Average density 0.6-0.7 Kg/dm3. - Energy savings.
  15. 15. 15 TEIDE REFRACTORY SOLUTIONS 20114. PRODUCTS FOR KILN CARS MAIN DESIGN PARAMETERS: -Resistance to sudden temperature changes > 90 cicles. (Air quenching) - Low linear reversible dilatation < 0.4%. - Resistance to softening under load. - Cold crushing strength.

  20. 20. 20 TEIDE REFRACTORY SOLUTIONS 2011 6. PRE-ASSEMBLING OF KILN CAR AT TEIDE’s- Before any delivery, we carry out a test assembling of the shapedgoods. For this purpose we have a reserved area in our factory.- This pre-assembling is a real-case verification of the project drawings.- The pre-assembling also allows to detect any deviations from the ideal case, and enables measures to be taken to offset the detected anomalies.

ASSEMBLING OF KILN CAR LINING AT CLIENT’S FACILITIESTypical TEIDE kiln car for a red brick tunnel kiln: * Levelling with a refractory castable: - To set a levelled base for the lining. - Seal the lining against passage of combustion gases. - Allows small adjustments of the height of the lining, e.g. in order to compensate chassis deviations from the nominal height.
  27. 27. 27 TEIDE REFRACTORY SOLUTIONS 2011Necessary, if an ondulated sheet serves as base.
  28. 28. 28 TEIDE REFRACTORY SOLUTIONS 2011Desirable, if a flat plate is used as base for the lining
  29. 29. 29 TEIDE REFRACTORY SOLUTIONS 2011* Calcium silicate plates, if considered on the design.* Perimeter with pressed corners and extruded or pressed lateral blocks, and the considered number of ceramic fiber joints.* Central supports, cut between parallell discs after beeing fired.Note: TEIDE prefers to supply supports without support lids, as eachlid would add tolerances to the total support height. * Light- weight castable for fixing, between the supports.* Insulating core of vermiculite - When required by the operating conditions, an upper insulating layer of light weight chamotte is applied.
  30. 30. 30 TEIDE REFRACTORY SOLUTIONS 2011* Sealing layer of ceramic fiber blanket.* Deck slabs (pressed or a mix of extruded and pressed) + Ceramic fiber joints.* Draught hole blocks or viaduct bricks.
