Hearth castable

I.Advantages of raw material: small porosity, high purity, good volume stability.

II.Advantages of resistance to slag and iron erosion: Compared with traditional ones, it has a smaller area ratio of resistance to slag and iron erosion.

III. Strength performance advantage: As the most important performance index of refractors-compressive strength, LMM silica sol material has rolling advantage!”
