(3) The opening performance is good, so that the tap hole can be opened quickly.




4)Good abration and erosion resistance of high-temperature slag, during tapping, the hole diameter  cannot be expanded by slag abration to ensure the stability of the molten iron flow.

(5) Good  volume stability ,  it has a certain porosity, which ensures that after blocking the taphole passage, there will be no excessive shrinkage  during the heating process, suitable porosity will make the volatile components out , no cracks and ensure good  sealing.
