AMITEK SILICA RAMMING MASS

AMITEK SILICA RAMMING MASS

AMITEK India manufacture ramming mass using good quality quartzite having very high purity Sio2 around 98.5% to 99.5%. The product is free from impurities and contains exact composition for yielding temperature of around 1700°C . High purity silica yields more lining life. It also results in considerable uniformity in physical properties. We manufacture finest quality of grains and powder of both quartzite and quartz for use in preparation of ramming mass. We are manufacturing these grains with strict quality adherence to provide best results.

Acidic Ramming Mass also known as Silica Ramming Mass is used in Coreless Induction Furnaces, for melting of scrap. High performance Silica Ramming Mix is designed to minimize erosion in induction melting. 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. AMITEK focuses on quality of silica ramming mass by providing particle size distribution to an optimum level, according to the furnace capacity and make, giving it a high density, trouble free and consistent linings.
