High alumina refractory mortars

VITSET ready mixed high alumina refractory cements / mortars are suitable for jointing, coating, and patching in all high temperature applications from 1450°C /2640°F up to 1860°C /3380°F. They are air-setting, with outstanding bonding properties at ambient and operating temperatures. Recommended bed for jointing firebricks is 3mm.

Vitset 45

Air setting refractory mortar, ready for use for trowelling and patching. Mortar forms a strong air-dried bond with all grades of refractory bricks for use up to service temperatures of 1700ºC /3100ºF

 

Examples of Applications:

Used for setting dense refractory bricks, high temperature insulation bricks and ceramic fibre blankets, boards,modules etc.

  • Foundry ladles
  • Foundry furnaces
  • Kilns and kiln cars - ceramics
  • Rotary cement kilns

Vitset 80

Ready mixed form ready to use suitable for setting bricks and can also be supplied at a thinner consistency for dipping bricks, coating and spraying. This material forms a strong air set bond with all grades of refractory bricks whether used as a joint or a render. The material is slightly expansile at 1540ºC ensuring good tight joints with no shrinkage problems at joint lines. It also has very good resistance to slag attack and it is very stable up to 1750ºC.

Examples of Applications:

Used in steel works and foundries where high temperatures are encountered such as setting high alumina bricks for safety linings in pouring ladles and setting bricks and purging nozzles in continuous casting tundishes.
