  • INQUIRY

Covering Agent adopts the composite carbon, free carbon technology to improve itself refractoriness, which makes this products with longer insulation time, small capacity, good spreadablity, and small termal conductivity, and the net rate is even more than 90%. Also what is more, dust float rate is very small, and this material do not bond to the furnace linning, especially for those high alkaline magnesia based, calcium magnesia based covering agent.


Covering Agent has good effect in absorbing impurity for the alkaline magnesia and magnesia calcium type furnace linning in the process of casting super low carbon clearn steel, thus to improve the slag’s stability and gurantee the steel quality.
