The light weight insulation bricks are very heavy in demand due to possessing
innumerable properties. One such attribute of these bricks is their light weight
which makes them pretty comfortable to use.

3. Features of Silica / Acidic Ramming Mass
 Ability of carrying a substantial load (50 LB per sq inch) to within a few
degree of its cone fusion point, viz.1710 to 1730 degree centigrade.
 Acidic Ramming Mass lining can be used in all type of plain carbon,
special and alloy steel except in case of 12 % Mn steel for which basic
lining is used.
 A high resistance to attack by the principal steel furnace fluxes viz. iron
oxide and lime.
 A higher thermal shock resistance in the temp range 600 to 1700 degree.
 Freedom from shrinkage at temp up to the melting point. Above all the cost
of Silica/Acidic ramming mass is just 1/6th of basic lining material.
Acidic /Silica & Pre-Mixed Ramming Mass
Specifications of Silica / Acidic Ramming Mass
 Silica Di Oxide - 99%
 Aluminum Oxide - 0.05 %
 Iron Oxide - Traces
 Softening Point - 1280 Degree C
 Porosity - 50 Compression Strength - 350 Kg/cubic cm Bulk Density -
2.0 TO 2.5 Kg/cubic cm
 PCE Value - ASTM NO. 31-32.
Premixed gives the following benefits to the user:
 Homogenous mixing through motorized mixture.
 Less wastage, as mixing is done by machines.
 Proper mixing of binder leading to optimum mixture.
 Consistent and longer lining and patching life.
 Quality Boric Acid is used to give best results.

Bottom Pouring Sets
We offer high quality bottom pouring sets throughout India and overseas. While manufacturing bottom pouring
sets, different fractions of refractory grog and non plastic/plastic (IS-6/IS-8) clay are mixed together
consistently. After grinding, these fractions of clay and grog are processed within a double shaft mixture for
making extruded paste.
The paste then obtained is taken to the high capacity screw presses to give a desired size and shape. The pressed
shapes are kept for natural drying and then are charged to tunnel kiln in order to take out the requisite moisture
and for giving proper heating to obtain required strength.
