Silica Ramming Mass

Silica ramming mass can safely be used up to an operating temperature of 1600 deg C. Since it expands very little, it is superior to both alumina and magnesia refractories to resist thermal shocks. Though silica lining has good endurance against thermal shock, it has poor resistance against steelmaking slags. Temperature control is very necessary for a satisfactory lining life.
Typical chemical composition of silica ramming mass consists of SiO2 – 98.9 % minimum, Al2O3 – 0.6 % maximum, Fe2O3 – 0.2 % maximum, and CaO – 0.1 % maximum. The typical physical properties of the silica ramming mass.

Benefits of using Silica Ramming Mass:

Here’s the following list of the benefits of silica ramming mass, which makes it the most commonly used refractory lining material for induction furnaces.

  • Meticulous and organized lining ability
  • Consistent performance
  • Long shelf life
  • Optimal bulk density
  • Wear resistant
  • Free from sintering agent


What is Silica Ramming Mass?

Silica ramming mass, also known as acidic ramming mass or quartzite powder or quartz powder. Silica ramming mass is a product to be used in Coreless Induction Furnaces for melting of scrap to liquid steel. It is a dry lining refractory that can be used for all types of iron, steel, aluminium and foundries. Silica Ramming Mass is used in the lining of induction furnaces. Quality of Silica Ramming Mass is directly related to the heating performance of the furnaces. Better quality of lining results in the smooth working of furnaces, optimum output, and better metallurgical control. A Proper check is exercised on the magnetic process to assure iron free Silica Ramming Mass and to assure proper composition of granules according to furnace capacity.

Furnace Specific Benefits: We are the manufacturer to give material as per the furnace capacity and make of the user. The granulation of the mix is optimized keeping in view the furnace make and capacity, thus giving maximum and best results. Ramming mix is characterized by thermal stability, corrosion resistance and wear resistance because it contains fewer binders, fire clay, and moisture compared to plastic refractories. Recommended for lining the iron melting coreless induction furnace. Premixed with the binder to customer’s specifications. Silica ramming mass can safely be used up to an operating temperature of 1700°C it expands very little so it is superior to both alumina and magnesia to resist thermal shocks.
