Advantages and application of ladle covering agent

Ladle covering agent adopts the composite carbon, free carbon technology to improve itself refractoriness, which makes this products with longer insulation time, small capacity, good spread porosity, and small termal conductivity, and the net rate is even more than 90%. Also, dust float rate is small, and this refractory material don't bond to the furnace lining, especially for those high alkaline magnesia based, calcium magnesia based covering agent. ladle refractories covering agents have good effect in absorbing impurity for the alkaline magnesia and magnesia calcium type furnace lining in the processs of casting super low carbon clean steel, thus to improve the slag's stability and guarantee the steel quality.

Features of ladle covering agents:
1. Insulation effect is good, the molten steel temperature drop is less than 0.5 ℃ / min.
2. Proportion of it is small, adding no steel splash, operating environment is good, pollution-free, safe, no adverse effects on the quality of molten steel.
3. Round particles, swimming is good, after the release was loose state, good spread, can quickly cover the full range of molten steel, adding no dust flying, do not pollute the environment.
4. No crust phenomenon after pouring.
