Benefits:

1) Excellent performance thermal shock, spalling and corrosion resistance.
2) Good mechanical strength and high refractoriness.
3) Reduce the residue and porosity of molten steel and good slag resistance.
4) Protect precious metals of the molten steel to reach high efficiency.
5) Labor and cost saving by prolonging campaign length.
