Item Code: ADRAM-IN-BRWe are offering wide range of Silica Ramming Mass Premixed with Boron Oxide. Silica Ramming Mass belongs to Acid group of refractories and is made from the purest raw materials available in this country. Very high purity of raw material gives high refractoriness to the mass. The mass has tendency to expand at about 800°C and this characteristic gives a very compact lining, showing high resistance to erosion and corrosion. The expansion tendency being reversible, crack formation during cooling does not occur.
