Our ramming mass is a product of super snow white crystalline quartz having 99.90% Silicon dioxide (sio2 ) and manufactured under strict quality control and calcined to eliminate the scaling tendency in a stabilized form, where silica neither expands nor contracts It is suitable for withstanding higher temperature up to l720oc
Specifications:
Sio2 - 99.90'/.
Al2O3 - 0.02%

For the first new lining, the requirement of Acidic Ramming Mass is almost 50% of the Furnace capacity in weight. It is required to be preheated to 70'-80'C. So as to eliminate moisture during the summer months In the winter season or rainy season. the mass should be preheated at a temperature of 140o - 150o C. Then after cooling it down to 50o - 60oC mix thoroughly 0.8 to 1.5 percent boric acid according to the size of the crucible. Usually, 12% of boric acid of medical grade is used for furnaces up to 3 tonnes Capacity Store the Ramming mass in dry and dust-free area.
