Refractory Coatings

Refractory linings in billet re-heating furnaces in hot rolling, sealed quench furnaces in heat treatment and most furnaces with refractory bricks face the following problems:
. Thermal shock cracking
. Energy leaks through thermal shock cracks in refractory
. Excessive furnace shell temperature heating
. Non-uniform heating in different zones of furnace
. Low refractory lining life
. High fuel consumption due to energy leaks

ESPON refractory coatings can withstand up to 1800 deg. C.and prevent the above problems.
Hence, life of the refractory is increased.
Due to high emissivity of ESPON refractory coating, heat is reflected back into the furnace, thereby reducing fuel consumption.Furnace retains high temperature for a long period even after shut down. This reduces start-up time when furnace is switched on next day. Heat uniformity is facilitated and maintained by the reflective ESPON coating. Furnace outer shell temperature does not geat excessively heated up.Due to its ability to withstand high temperature, ESPON refractory coatings are also used in Acid Regeneration Plants to prevent slag adhesion.

ESPON Refractory Coatings lead to reduced fuel consumption and increased refractory lining life.

ESPON-RC3 is a protective coating for refractory brick lining in furnaces.

ESPON-RC3 is a zircon based refractory coating with special additives and powerful binders that can withstand high temperatures up to 1900 deg. C. and can resist corrosive gases. It must ideally be used on a new refractory lining for best results. However, if used on old or partially worn out refractory lining, care must be taken to repair the lining properly using ESPON-RC3 powder.

Benefits of ESPON-RC3 Refractory Coatings:

  • Reduces thermal conductivity of refractory lining.

  • Improves thermal shock resistance.

  • Increases emissivity of refractory lining, reflects heat into the furnace.

  • Reduces fuel consumption in furnace operation.

  • Increases refractory lining life, reduces furnace maintenance downtime.

  • Prevents carbon deposits on burner blocks.

  • Prevents slag adhesion to refractory lining. Also found useful in Acid Regeneration Plants.
