Silica Ramming Mass

From us, global buyers can obtain the superior grade Silica Ramming Mass within their budgetary limits. Silica Ramming Mass is widely used in lining of the induction furnaces, etc. As a responsible Manufacturer, Supplier and Exporter, we utilize only the best techniques to make the Silica Ramming Mass that is 100% compliant. Also, we pay special attention towards packaging and transportation to ensure safe deliveries.

More About Silica Ramming Mass :
The role of Acidic Ramming Mass in steel melting through induction Furnace is very important. Due to its important property to with stand thermal shocks without developing any cracks due to interrupted powder supply which is the case throughout our country. We have taken initiative to develop acidic ramming mass of high quality silica Quartz having heavy density.


Product : 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 stabilized form, where silica neither expands nor contracts. It is suitable for with standing higher temperature upto l720oC.


Specifications :

  • SiO2 - 99.90'/.
  • Al2O3 - 0.02%
  • Free from Iron contents
  • Softening Point : - 128oC
  • Porosity : 50
  • Compression St : 350 Kg /CM2
  • Bulk Density : 2.00 to 2.2 Ton/M3
  • PCE Value ASTN No : 31-32


Important Features :

 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 70o-80oC so as to eliminate moisture during summer months. In 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.


Our Acidic Ramming Mass :

Has got three Categories as under :

  •  Grade M1 Suitable up to 1.5 Tonne furnace capacity.
  • Grade M2 Suitable for 2 to 3 Tonne furnace capacity.
  • Grade M3 Suitable for 5 Tonne furnace capacity.


In addition to all we guarantee more lining life with our material compared to any other. While sending your queries and orders please do specify the capacity of furnace and type of steel you are manufacturing to enable us to give you the correct combination of Material and advise.


Application : Our Acidic Ramming Mass is used by mixing boric acid 0.8% To 1.5% according to the type of metal Low for Steel and high for cast iron melting. Complete lining guidance can be furnished as required according to the size of furnace.


Packing : Standard Packing available in 50 kg. HDPE bags & 1 or 1.25 MT Jumbo bags with liner inside, or as per customer requirements.
