Ramming mass used n induction
furnace is made of SiO2 ( Silicon
dioxide). Silica ramming mass ( SiO2) is acidic in nature. Ramming mass is used
in powder form for lining or ramming in induction furnace. Good quality quartzite
stone is used to produce the Silica. Very high purity quartzite stone is used
to produce the ramming mass.. Quartize is broken crushed in machines, then it
is powdered. If there will be impurities in the mineral stone, then it will
create problem at final stage in induction furnace. Impurities in stone will
produce more amount of the liquid at heavy temperature. It will be lower down
the chemical and mechanical resistance property of the lining. High purity
silica gives longer life to induction furnace. Material produces from high
quality silica is uniform in quality and physical properties.
Ramming mass are compact in
comparison to other linings. Compactness of the Ramming mass depends on the
proportion of the size of the granules in Ramming mass powder. Proportion of
the size of granules is known and granulometrics. Granulometric composition should be in such
way that there should be minimum vacant or open space among the particles.
An ideal granulometric
composition of commercial acidic ramming mass is given below.
SIZE PERCENTAGE
4 mm to 1mm 33%
1 mm to 0.20mm 30%
0.20mm to 0.06mm 17%
0.06mm & below 20%
Proportion of the finest
material is very important, as it takes part in the sintering reaction in
furnance. If the fine particles are more than recommended percentage then it may lead to adverse effect of on
performance of ramming layer.
Special attention should be
paid towards the proportion of fine size, it should be within a certain
tolerance. There is adverse effect on the service behavior of lining if fine
particles present in more quantity than required. Since the finest particles
mainly takes part in the sintering reaction.
We are
lading producer and exporter of silica ramming mass from India. Silica ramming
mass can safely be used up to an operating temperature of 1600°C it expands
very little so it is superior to both alumina and magnesia to resist thermal
shocks. Secondly its cost is very low in comparison to alumina and magnesia.
Please contact for technical product details and your requirement.
We will be please to serve you for the best performance of your operations.
