Rice Husk Ash
Rice husk ash is mainly used in the steel industry as an insulator in the manufacture of high quality steel forgings. This allows forged steel to cool down gradually. The price of rice husk ash is quite high at the steel plant gate level (as high as 400 USD/ton), as high quality ash is required for this purpose. The density and unburnt carbon content of ash should be as low as possible. A few companies play a major role in this business.
Apart from the above, rice husk ash is also used in cement industries as a substitute to portland cement. Research work is also going on regarding silica chip manufacture as the silica content of the ash is very high.
Only a few boiler suppliers around the world have mastered the technology of producing high quality ash in their boilers. However, not all boilers can produce high quality ash.
We have worked with several rice mills exporting rice husk ash to Europe and Korea.
