Our Products
BIOTHERM
Our Biotherm products are covering powders based on rice husk ash. It is a highly insulating powder that is utilized
for reducing oxidation, heat loss and hydrogen build-up by being applied to the molten surface in the tundish .
This compound is formulated as a mixture of salts that is added at the base of molten metal in tundish and helps in
reducing the cost of re-melting of alloys with improved properties and can be availed in acidic and basic formulations
required according to the purpose of use. Biotherm has a very low carbon content, creating the ideal basis for producing
low-carbon steel.
MICRO SILICA
Whitespice Chemicals are manufacturers of Micro Silica – a mineral admixture which has very fine silicon dioxide.
Micro Silica is produced after processing special grade Rice husk ash. This is shorted, pulverized, air classified
and packed in specified packing for ease of handling the material at site. Standard specifications for silica fume used
in cementitious mixtures are ASTM C1240,EN 13263.
On adding Micro Silica to the cementatious mix, the resultant concrete has more of strong calcium-silicate hydrates and
less of the weak and easily soluble calcium hydroxides than the normal concrete mix. As Micro Silica particles are small
they disperse among and separate the cement particles and this results in fine, uniform mix that has higher compressive,
flexural, and bond strength. Silica fume also reduces the permeability of concrete to chloride ions, which protects the
reinforcing steel of concrete from corrosion, especially in chloride-rich environments such as coastal regions and those
of humid continental roadways, runways and saltwater bridges.
RICE HUSK ASH GRANULES
RHAG (Calcined rice husk ash granules)
Fine grinded RHA of selected composition is spray dried to 120-180 micron. These are specially designed nodular products for rainforcement of refractory mass applied in tundish, ladle, medium temperature furnaces etc.
RHAN - MG
Compacted and nodularised balls perfected to desired composition with MGO blend to render it inert to ladle/tundish refractories.
RHAN (Calcined rice husk ash nodule)
Compacted and nodularised balls perfected to desired composition
Fine grinded rice husk ash granules of selected composition is spray dried to 120-180 micron. This is an effective tundish cover for insulation on slag free molten steel in continuous casting. It is an effective medium to retain that minimum superheat necessary for a smooth casting operation by preventing radiant heat loss from the surface of the molten steel. Using RHA in its granular form prevents air pollution, reduces wastage, insulation and excellent spreadability.
