Silica Ramming Mass, also known as Acidic Ramming Mass, plays a crucial role in induction furnaces during melting of steel. This substance is used to line induction furnaces and its quality decides smooth working and more efficient output from the furnace. Ramming mass has a very important quality of withstanding of easily absorbing thermal shocks. It also does not develop cracks because of frequent power cuts during the operation of the induction furnace. Rong Sheng makes very high quality silica ramming mass containing very dense silica quartz.
