Typical application
MS 6 is used in a wide range of applications including:
- regenerator transition layer and chamber walls,
- forehearth burner blocks,
- bottom sub-paving,
- electrical furnace superstructure.
If mortar is required, use ARKAL MORTAR.
For more complex and larger shapes refer to ARKAL 60 V.
For more severe alkali or boron vapor corrosion, refer to ZMP or PROMOLD.
For a higher creep resistance application, refer to MS 4 F and MS 75.
